::...*...*it is the number of atoms in a MOLECULE ..for EXAMPLE atomicity of Nitrogen DIOXIDE is 2 (N2)

a METAL ESPECIALLY transition metal. it is a metal as it is LUSTROUS ,ductile ,malleable.

y l by c and then divide A by the PRODUCT to SOLVE for MOLAR absorptivity. For example: Using a cuvette with a LENGTH of 1 cm, you MEASURED the absorbance of a solution with a concentration of 0.05 mol/L. The absorbance at a wavelength of 280 nm was 1.5.

um ionsThere are 12 SODIUM ions located at the edge center of a unit CELL in Sodium Chloride CRYSTAL.

qual to D)isothermal work.Explanation:Isothermal process is the process in which temperature of the SYSTEM remains constant. Therefore, INTERNAL energy remains constant. For an ideal gas in an isothermal process, ∆U=0=Q-W.where, ∆U= internal energy             Q = HEAT ABSORBED or released             W = work DONE by the system or on the system

s of oxygen INVOLVED is 0.5g ACCORDING to the law of CONSERVATION of MASS.

ting point of ICE: PRECAUTIONS: 1.The bulb of the THERMOMETER should be kept SURROUNDED with ice cubes. 2.Ice should be stirred regularly to keep a uniform temperature throughout.3.Note temperature by keeping your eyes in line with the level of mercury.For boiling point of water:Precautions:1. The bulb of the thermometer should be kept about 4-5 cm above the surface of water.2.Pieces of pumice stone should be added to water before heating to AVOID bumping.3.Heating of water should be done by rotating the flame.Note temperature by keeping your eyes in line with the level of mercury.

re four principle orbitals (s, p, d, and f) which are filled according to the energy level and valence electrons of the element. ... ALTHOUGH the elements can display MANY different oxidation STATES, they usually exhibit a common oxidation state DEPENDING on what makes that element most stable.

ompounds in which PROPERTIES of somes elements are same are known as CHEMICAL twins.eg. DIAGONAL relationship between LI and Mg and Be and Al

MATE ❤️❤️❤️ HERE IS UR ANSWER....HALOGENS AND ATOMS OR ELEMENTS WHICH HAS ONE ELECTRON IN ITS OUTERMOST ORBIT...WE ARE HIGHLY ELECTRONEGATIVE..THEY ARE AT THE EXTREME RIGHT POSITION OF THE PERIODIC TABLE...WE ARE KNOWN AS HALOGENS BECAUSE THEY HAVE 7 ELECTRONS IN THE OUTERMOST SHELL....AMONG ALL THE HALOGENS FLUORINE HAVING HIGHEST ELECTRONEGATIVE POWER..AND CHLORINE HAS HIGHEST ELECTRON AFFINITY....HOPE THIS WILL HELP YOU ❤️ ❤️❤️STAY BLESSED ❤️ ❤️❤️@PANKHUDI NEWELY JOINED ✌️ ✌️

ur answerWhen fresh MILK changes to curd its pH will DECREASE. It is because curd CONTAINS lactic acid. Since ACIDS GENERALLY have a low pH value, so when fresh milk changes to curd its pH will decrease.Hope it helps:)

der is EQUAL to ½(E in BMO - e in ABMOusing thisO2 will have bond ORDER 2O2+ will have bond order 1.5

- 0.025 atmSolution:- The given balanced equilibrium equation is:2NO_2(g)\leftrightarrow 2NO(g)+O_2(g)2NO2​(g)↔2NO(g)+O2​(g)From the equation, there is 2:1 mole RATIO between NO and O_2O2​ .Their equilibrium partial pressure would be in the ratio. Equilibrium partial pressure of OXYGEN is given as 0.25 atm. So, the equilibrium partial pressure of NO = 2(0.25 atm) = 0.50 atmEquilibrium expression for the given equation is written as:Let's plug in the values in it and solve it for equilibrium partial pressure of NO_2NO2​ . Let's SAY the equilibrium partial pressure of nitrogen dioxide is p.100=\frac{(0.50)^2(0.25))}{p^2}100=p2(0.50)2(0.25))​100=\frac{0.0625}{p^2}100=p20.0625​On rearranging the above equation:p^2=\frac{0.0625}{100}p2=1000.0625​On taking square root to both sides:p=\frac{0.25}{10}p=100.25​p = 0.025 atmSo, the equilibrium partial pressure of NO_2NO2​ is 0.025 atm.

nking PROPERTY and tertravalent NATURE of CARBON

alyst are generally d BLOCK metals They show changeable valency and can create unstable compound in a REACTION they create a compound in a reaction which gives the reactants more area to create compound EASILY and after the reaction they get separated HOPE it HELPS

ing FUNNEL is used to separate the mixture of TWO IMMISCIBLE liquids. Kerosene oil and water do not mix with each other and form two separatelayers. ... Thus, the water is first collected in the beaker. and the kerosene is collected in another beaker.

Mix an ACID acid with water it will result in the formation of hydronium ions in the water if you makes a SOLUBLE base that is an alkali it will result in the formation of HYDROXIDE ions.

as NA + has given 1 electron it's EASY NUMBER is 10 so there is 10× 6.022×10^23 ELECTRONS in 1 mole there is .1×6.02×10^23×10 electrons in .1 electrons molehope it helps

n't DEALS with RATE of REACTIONS.

re is the QUESTION

don't know the equation equation is 2C2H2 + 5O2=4CO2 + 2H20. According to the gay lussac's law under the same conditions of TEMPERATURE and pressure gases occupy the same volume at the product and reactant side.2 MOLE of ethyne GAS occupies 20 cm cube of volume show ONE mole of ethyne gas occupies 10 centimetre cube volume. So 5 moles of oxygen occupies 20 x 5 that is 100 cm cube of volume.Done. Hope it helps
