alization reaction OCCURS when a strong acid reacts with a strong BASE to produce water and a salt (ionic compound). In our case, sulfuric acid (strong acid) will react with sodium hydroxide (strong base) to form water and sodium sulfate:H 2 S O 4 + 2 N a O H → N a 2 S O 4 + 2 H 2 OWE start with the units that we want to end up with and we set that equal to our given value, which will be MULTIPLIED by a conversion factor (the molar ratio from the balanced chemical equation). The  98.08 G mol  represents the molar mass of sulfuric acid and the  40.0 g m o l  is the molar mass of sodium hydroxide.So what we have is,g2NaOH=25.0gH2SO4×1molH2SO4/98.08gH2SO4×2molNaOH/1molH2SO4×40.0gNaOH/1molNaOH=20.4gNaOH

al qualitative inorganic analysis is a method of analytical chemistry to find the elemental composition of inorganic compounds. It is MAINLY focused on detecting ions in an aqueous solution. The solution is treated with reagents to test for reactions characteristic of certain ions, which may cause color change, solid forming, and other VISIBLE changes.Cations are divided into six GROUPS. Each group has a common reagent that can be used to separate them from the solution. Because CATIONIC analysis is based on the solubility products of the ions, meaningful results can be obtained only if separation is performed in a specified sequence. This is due to the fact that some ions of one group may also react with the reagent of another group. For EXAMPLE, both Ba2+ and Sr2+ will react with the SO42- ion to form a solid. Hence, mathematical calculations should be done before choosing the SO42- ion for selective precipitation in a solution that may contain both Ba2+ and Sr2+.

the volume of 6M HCl required to prepare 1 L of 3M HCl = x L Volume of 2M HCl required = 1 - x L Apply molarity EQUATION M1V1 + M2V2 = M3V3 6 � (x) + 2 ( 1-x) = 3 x 1 6X + 2 - 2X = 3 4x +2 = 3 4x = 3 - 2 4x = 1 x = 1/4 = 0.25 L so, volume of 6M HCl required = 0.25 L volume of 2M HCl required = 1 - 0.25 = 0.75 L

rmation in sf4 by using the concept of HYBRIDIZATION:First we have to find out the hybridization of given molecule by using below steps 1)find the total number of VALANCE electrons for sf4Here 6 valance e⊕ in "s" and 7 valance e⊕ in "f" atom.Total valance electrons=6+4*7                                       =6+28                                       =342)Divide the total valance electrons by 2 (If the total valance electron is less than 8 and if the total valance electron is grater than 8 then we have to divide it by 8).if any semiconductor we can consider it as by .we get the steric number is 4H=5 3)then assign the hybridization ACCORDING to the steric number                 Steric number                 Hybridization                            2                                       sp                            3                                       sp^2                            4                                       sp^3                            5                                       sp^3d                            6                                       sp^3d^2Bond formation in ccl4 by using hybridization concept:1)first we have to find the hybridization of ccl4                                =4+4                                 =82)Divide the total valance electron by 2 we get                                              =8/2                                              =43)Assign the hybridization according to steric numberwe get hybridization of sp^3Then the geometry is tetrahedralAnd shape also tetrahedral

arity of HCl be M1 and vol be V1 M1v1 = 0.1×40 = 4 LET molarity of NaOH be M2 and vol be V2 M2v2 = 0.45×10= 4.5 Clearly m2v2 >m1v1 THEREFORE resulting SOLUTION will be basic. So molarity if resultant solution ll be M = m2v2 - m1v1/ v1 + v2 = 0.01 POH = -log(0.01) = 2 Therefore, pH = 14 - pOH = 12.

.001 N NaOH = 11 So, the pH of the NaOH Solution should be lowered to 10 which WOULD be pH=10 The weight of NaOH present in 10 ML.of 0.001N NaOH=0.001 x 40/100= 4 x 10–4 If the concentration of the NaOH is 0.0001 then it's pH will be 10! 10 ml.of 0.001M NaOH will contain =10 x 0.001=0.01 m.mole. But if you add 8.1 ml.of HCl, then it will add 0.0081 m.moles of HCl, in the mixture and the resulting Solution will contain (0.01–0.0081)= 0.0019 m.moles of NaOH in 18.1 ml.!!!. The concentration will be =0.0019/18.1=0.000105 N. Now the pH will be 1 UNIT lower. ie., approximately =10. But accurately it is =- log(0.000105)=14–3.9788=10.02. OK.

ing that goes down any of the drains in the house (toilets, showers, sinks, laundry machines) TRAVELS first to the septic tank. The septic tank is a large-volume, watertight tank which provides initial treatment of the household wastewater by intercepting solids and settleable organic matter before disposal of the wastewater (effluent) to the drain FIELD.FUNCTION OF THE SEPTIC TANKWhile relatively simple in construction and operation, the septic tank provides a number of important functions through a complex interaction of physical and biological processes. The essential functions of the septic tank are to: receive all wastewater from the house separate solids from the wastewater flow cause reduction and decomposition of accumulated solids provide storage for the separated solids (sludge and scum) pass the clarified wastewater (effluent) out to the drain field for final treatment and disposal.Primary TreatmentAs stated, the main function of the septic tank is to remove solids from thewastewater and provide a clarified effluent for disposal to the drain field.The septic tank provides a relatively quiescent BODY of water where thewastewater is retained long enough to let the solids separate by bothsettling and flotation. This process is often called primary treatment andresults in three products: scum, sludge, and effluent.Scum: Substances lighter than water (OIL, grease, fats) float to the top,where they form a scum layer. This scum layer floats on top of the watersurface in the tank. Aerobic bacteria work at digesting floating solids.Sludge: The "sinkable" solids (soil, grit, bones, unconsumed food particles)settle to the bottom of the tank and form a sludge layer. The sludge isdenser than water and fluid in nature, so it forms a flat layer along thetank bottom. Underwater anaerobic bacteria consume organic materials in thesludge, giving off gases in the process and then, as they die off, becomepart of the sludge.Effluent: Effluent is the clarified wastewater LEFT over after the scum hasfloated to the top and the sludge has settled to the bottom. It is theclarified liquid between scum and sludge. It flows through the septic tankoutlet into the drain field.

a simple compound ACTUALLY?⇒ Its a molecular bond of the atoms of similar kind of ELEMENT or of different kinds.How the bond is actually?⇒ The bond is  nothing but by sharing ELECTRONS. We often use the term chemical bond. But what is this chemical bond actually? ⇒ There is no bond as chemical or physical. Its only the combination of electrons of two atoms for being stable in there state. This bond may be ionic or covalent.What is ionic bond?⇒ Ionic bond is that bond in which there is a gaining of charge. In ionic bonds an atom always loses its electron an forms cataion and an atom gains electron and forms anaion.In Ionic bond generally found between a metal and a non-metal. Because, a metal has always 1 or 2 or 3 electrons on its outermost shell where a non-metal has always 5 or 6 or 7 electrons. And its easy for a metal to be stabled by losing electrons and thus, it forms cataion or gains a positive charge. In the similar way its easy for a non-metal too to be stabled by gaining electrons and thus forms anaion. What is covalent bond?⇒ A covalent bond is such in which there is no gaining of charge but rather the atoms mutually share their electrons and be stabled. It is generally found between two non-metals.* It should have to be noted that, in both the cases there is the exceptions about he hydrogen and metalloid. Then what happens in case of hydrogen?⇒ Hydrogen has only 1 electron and only 1 orbit. And we know that the first shell never can hold more than 2 electrons and that's why hydrogen often behaves as LIKE the alkali metals and sometimes as like the halogens. What happens in case of metalloids?⇒ Metalloids have 4 electrons in their valence shell and it makes them partially stable and they generally don't react with other elements as like the nobel gases. But sometimes they may react also and then they may form either cataion or anaion, they may form either ionic bond or covalent bond as well.Then what are the rules to write the equations for the compounds?⇒ *First of all write the symbols of the elements.* Never state the charge of the elements.* State the molecular numbers by which they reacted.* But mention the valence electron on the either side that means in the subscript of the other element.* And always right the valence electron and the number of the atoms of each element in the simplest ratio with the respect to the other elements of that reaction.Such as for an ionic compound_MgCl₂ ⇒ Mg + 2ClHere, one molecule of magnesium and two molecules of chlorine are reacting.We know that, Mg has 2 electrons in its valence shell and Cl has 7 electrons and that's why Mg reacts with 2 atoms of chlorine to be stabled and as well as the two atoms of chlorine too get stable.The chain reaction shows a bond as like this_Cl --  Mg -- Cl ⇒ Mg²⁺ + 2Cl⁻⇒ Mg₁Cl₂ ⇒ MgCl₂For a covalent compound such as _H₂O  ⇒ 2H + OHere, 1 molecule of O reacts with 2 molecules of H but in this case, there is no formation of charge as they mutually share their electrons to be stabled.The chain reaction is somehow like_H -- O -- H  ⇒ O + 2H  ⇒ H₂O

ng to HUCKLE's RULE a compound is aromatic if1) there is CONJUGATION in whole ring2) it is a flat cyclic system (or sp2 hybridised carbon)3) (4n+2) pi electrons should take part in resonance and According to him the compound is Anti Aromatic if1) same as above 2) same as above3) 4n electrons should take part in resonance now in this question, first 2 conditions are MET but third condition is not met as it has total 16 pi electrons i.e. 4n and not 4n+2 electrons Hence it is Anti aromatic and not aromatic HOPE it helps!!!!

re many types of OIL and their properties, which may have changed during use, dictate how they are classed when they become waste. Technical guidance to help you classify your waste can be found on.The most common waste oils, DERIVED from fuels or lubricants, ORIGINALLY come from petroleum oil, sometimes known as mineral oils. Many lubricants may also contain synthetic components.But other common oils, including vegetable based materials used for cooking can become waste as well.Waste oil is HARMFUL to the environment and some, for example used ENGINE oils, may cause cancer, so it needs to be managed carefully. You may need to account for Health and Safety guidance as well as the environment.

adius of Beryllium is very small hence it have HIGH polarizing POWER. When compared to the remaining elements of same group elements, it has very high polarizing power.        For this reason, the compounds of beryllium are essentially covalent in nature. In fact beryllium salts are soluble in organic solvents and sparingly soluble in water. The melting point and boiling point of the beryllium little bit low than remaining alkaline EARTH metals.       Beryllium oxides are react with both acids and alkalis therefore its oxides are amphoteric in nature.  The remaining group 2 metal oxides are more ionic.        The following chemical reactions of beryllium shows heir hygroscopic nature.        Halides of beryllium LIKE beryllium fluoride and beryllium chloride are covalent and polymeric. And these are sublime and do not conduct electricity. All the above properties CLEARLY show the covalent nature of the halides.

y can be accounted by the electron availability, in the case of is more electron availability than .   This is due to various atoms like H and F electronegative ions connected with nitrogen.       The LONE pair of N in is concentrated on N and either can act as an electron pair donor (Lewis base).       However in have less electron density on N because F ATOM attached is to C, and it is highly electronegative THEREFORE it can be act as a Lewis base.       HENCE,   is basic and is not basic.

olar molecule can have highly polar bonds, as molecular dipole is a vector sum of different bond dipoles.For example, there are TWO strong C=O dipoles in , but the molecule's net dipole moment is zero.Dipole moment is is as follows in below diagram.  molecule is symmetrical therefore, because it is a linear molecule. In this molecule, CARBON SHARING two OXYGEN atoms, the magnitude of dipole is equal in magnitude but points in opposite directions.

rength and bond length are influenced by hybridization. Especially it completely depends upon the s- orbital.s- orbitals are closer to the nucleus therefore FORMS stronger and SHORTER bonds The length of the bond and the strength of the bond are INVERSELY linked, i.e. the LONGER the bond is, the WEAKER the bond strength.‘s’ and ‘p’ character in different hybridization states is as follows.Therefore, order of bond strength in different hybridization states is as follows.

st Ionization EnergyThe energy needed to remove one or more ELECTRONS from a neutral atom to form a positively charged ion is a physical property that influences the CHEMICAL behavior of the atom. By definition, the first ionization energy of an element is the energy needed to remove the outermost, or highest energy, electron from a neutral atom in the gas phase.The PROCESS by which the first ionization energy of hydrogen is measured would be represented by the FOLLOWING equation.H(g)  H+(g) + e-Ho = -1312.0 kJ/mol

3 HalidesTrihalides, MX3As shown in [LINK] all the combinations of Group 13 element (M) and halogen (X) exist for the trihalides (MX3), except thallium(III) iodide. It should be noted that while there is a compound with the general formula TlI3, it is actually a thallium(I) compoundThe trihalides of boron are all MONOMERS with a coordination number of 3 ([link]), as evidence from their low melting points ([link]). In contrast, the fluorides and chlorides of the heavier Group 13 elements (except GaCl3) are GENERALLY ionic or have a HIGH ionic character, with a coordination number of 6 ([link], [link] and [link]). The bromides and iodides (except InBr3) are generally dimeric with a coordination number of 4 ([link]) and have molecular structures involving HALIDE bridging ligands ([link] and [link]). AlCl3 is unusual in that in the solid state it has an ionic structure, but it is readily sublimed, and in the vapor phase (and liquid phase) it has a dimeric structure ([link]).Hope this helps you too Mark as a brainliest
