(a) What do you mean b stoichiometry?
(b) Define atomicity of a gas. State the atomicity of Hydrogen, Phosphorus and Sulphur.
(c) Differentiate between N2 and 2N.

(a)A balanced chemical equation is a recipe for a reaction. It contains a list of all the reactants and products as well as their relative proportions. Using a balanced chemical equation to calculate amounts of reactants and products is calledstoichiometry.
(b)Theatomicityof an element is the number of atoms present in one molecule of the element.
Hydrogen: diatomic
The number of atoms present in a molecule ofphosphorusis 4. So theatomicity of phosphorusis 4
Atomicityofsulphur= 8. ie, in one molecule ofsulphur(S8), eight atoms ofsulphurare present.
(c)2Nmeans two molecules ofNitrogenatom whileN2 means two atoms ofnitrogen inone molecule. N2 shows that twonitrogenare bonded with a covalent bond, and it becomesnitrogengas whereas2Ndoes not show any bond, it just shows two number ofnitrogen.
