.❤❤❤ here is ur answer...(1) The process of MIXING atomic orbitals to form a set of new EQUIVALENT orbitals is termed as hybridisation. There are three types of hybridisation,(i) sp3 hybridisation (involved in saturated organic compounds containing only single covalent bonds),(ii) sp2 hybridisation (involved in organic compounds having CARBON atoms linked by double bonds) and(iii) sp hybridisation (involved in organic compounds having carbon atoms linked by a triple bonds). hope it helps...PLZ mark me as brainliest my dear !!!❤❤❤

ent One:Standardization of Hydrochloric AcidObjectiveTo determine the concentration of hydrochloric acid (HCL) (by measuring thevolumes of it) using SODIUM carbonate (Na2CO3) as the primary standard involumetric analysis, using the method of acid-base titration.Theoretical Principles behind TitrationIn this acid-base titration, we are trying to determine the concentration of hydrochloricacid by using a base sodium carbonate. It involves reacting a KNOWN VOLUME of asolution (HCL) with a standard solution (Na2CO3). The whole experiment was dividedinto two parts; firstly, we need to prepare a standard solution of sodium carbonate,while second, titrate sodium carbonate solution against hydrochloric acid solution.A. Preparation of Standard Sodium Carbonate Solution The standard solution is obtained by dissolving a known mass of anhydrous sodiumcarbonate powder in deionized water. Later than, continues add deionized water intoa 250 cm3volumetric flask until the MENISCUS just touches the graduation mark. Theequation is following:Na2CO3 (s)+ H2O(l)--→ 2Na+(aq)+ CO32-(aq)+ H3O+(aq)+ OH-(aq)The mass and the relative molecular mass of anhydrous sodium carbonate areknown. Thus we can calculate the number of MOLES of sodium carbonate added tothe standard solution. The expression is following:Number of moles of Na2CO3= actual mass added /relative molecular massThen, we can calculate the morality of sodium carbonate. The expression isfollowing:Concentration of Na2CO3= no. of moles of Na2CO3/ volume of solution1

rk deals with treatment of the sodium titanate cake results from roasted titania slag using 60% sulfuric acid solution. The working SAMPLE produced by roasting titania slag with NACO3 at 850 °C. After roasting V and Cr species as impurities in the roasted sample are converted to WATER soluble species as NaVO3 and Na2CrO4 before acid treatment however, the insoluble sodium titanate products (NaFeTiO4, Na8Ti5O14, Na6Ti2O7 and Na2TiO4) are then subjected to H2SO4 acid dissolution. The produced sulfate solution is subjected to hydrolysis step in presence of OXALIC acid as a reducing agent. The hydrolyzed precipitate after filtration and washing with H2SO4 solution and warm water is dried at 100 °C and calcinated at 850 °C to prepare high pure TiO2 (99.8%) besides removing ferrous sulfate (FeSO4) as a byproduct from the sulfate solution.

he atomic number of the element PRESENT in the THIRD period and seventeenth group of the periodic table. ... Hence, the element in the 17th group of the third period has atomic number Z = 17 ,CHLORINE(Cl) with atomic mass 35.453, which is a p block element.

cal change can be CONFIRMED by any of the following observations: Change in temperature Evolution of gas For EXAMPLE: Calcium oxide reacts vigorously with water to produce calcium hydroxide. During this process, a large amount of heat is also evolved, which increases the temperature of the system. This confirms that a CHEMICAL reaction has taken place. Also, when calcium carbonate is heated, it DECOMPOSES to form calcium oxide and carbon dioxide. In this reaction, calcium carbonate breaks down to form calcium oxide and carbon dioxide. Here, evolution of the gas (carbon dioxide) confirms that a chemical reaction has taken place.

s the ionic product of water increase with the increase in temperature? The dissociation of water molecule is an ENDOTHERMIC REACTION. By Le Chatelier's principle, increase in the temperature will SHIFT the equilibrium towards the direction where the HEAT is ABSORBED, i.e, where the endothermic reaction happens.

xy or hydroxyl group is the entity with the formula OH. It contains oxygen bonded to hydrogen. In organic chemistry, alcohol and carboxylic acids contain hydroxy groups. The anion [OH−], called hydroxide, consists of a hydroxy group. hydroxyl groups are not highly reactive, but they readily form hydrogen bonds and contribute to MAKING molecules SOLUBLE in water. Alcohols and SUGARS are "LOADED" with hydroxyl groups. Carbonyl groups have one oxygen atom double-bonded to a carbon atom (SYMBOLIZED as C=O).

m is a highly REACTIVE element it reacts with almost EVERY other element to perform displacement reaction.when food containing iron salt is cooked in aluminum,it reacts with iron and PRODUCE any other product that even can be harmful to us.hope it helps!please mark me as BRAINLIEST if you are satisfied

d form yellow turbidOn passing H2S through an aqueous SOLUTION of SO2 oxidation of H2S occurs while SO2 is REDUCED to produce ELEMENTAL sulphur which causes the yellow turbidity.2H2S + SO2(aq) ---------> 3S + 2H2O

dation state of an element is related to the number of electrons that an atom loses, GAINS, or appears to use when joining with ANOTHER atom in compounds. It also determines the ability of an atom to oxidize (to lose electrons) or to reduce (to gain electrons) other atoms or species. OXIDATION results in an INCREASE in the oxidation state. Reduction results in a decrease in the oxidation state.  If an atom is reduced, it has a higher number of valence SHELL electrons, and therefore a higher oxidation state, and is a strong oxidant. For example, oxygen (O) and fluorine (F) are very strong oxidants.Both oxide and fluoride ions are highly electronegative and have a very small size. Due to these properties, they are able to oxidize the metal to its highest oxidation state.

not conduct electricity in SOLID state because their particles are CLOSELY bounded and there is a strong FORCE of attraction between them which does not LET them move.However they conduct electricity in their molten state due to LOOSE attraction of molecules .

e!!!____________________________Aryl halides are RELATIVELY unreactive toward nucleophilic substitutionreactions. This LACK of reactivity is due to several factors. Steric HINDRANCE CAUSED by the benzene ring of the aryl halide prevents S N2 reactions. Likewise, phenyl cations are unstable, thus MAKING S N1 reactions impossible.===='''''"''===:::::::::::::::::=========''''''''====

e!!!!_______________________However, CARBON compounds are more stable, since the carbon bonding allows for the atoms of carbon and OXYGEN to be closer and held more firmly that those of silicon. Because it is a BIGGER ATOM and there are more SHIELDING effects by the electrons, the bonds between atoms with silicon are not as strong.____=====____=====____====____

m is found as toxic heavy metals.Chromium toxicity: Industries LIKE electro plating, metallic cleansing and dyeing processing, cement, and leather tanning industries are the major source and PLAY role in discharging chromium into the environment. Hexavalent chromium is the main chromium species used in industrial processes, INCLUDING manufacturing of metallic alloys (the most IMPORTANT use of Cr), chrome leather tanning, metal cleaning processing, electronics and wood PRESERVATION and so on, and is therefore the most common pollutant in a wide variety of industrial wastes

y, or molar concentration (M), is defined as the number of MOLES of a SUBSTANCE, or "solute," dissolved in 1 LITER of SOLUTION. Molarity is not to be confused with "molality," which is concentration expressed as moles of solute per kilogram of solvent.

nes, the only intermolecular forces are van DER Waals dispersion forces. Hydrogen bonds are much stronger than these; therefore, more ENERGY is required to separate alcohol molecules than to separate ALKANE molecules. It also SHOWS that the boiling point of alcohols increase with the number of CARBON atoms...

dium CHLORIDE is heated in an atmosphere of SODIUM VAPOURS, the excess of metal atoms get deposited on the SURFACE of alkali metal crystal. Halide IONS then diffuse to the surface where they combine with metal ions.
