(a)
Interpretation:
The balanced equation should be determined for the reaction of
Concept introduction:
Chemical equation is the representation of a
Reactant of a chemical reaction is the substrate compounds or the compounds which undergo a chemical reaction.
Product of a chemical reaction is the produced compounds or the compounds formed after a chemical reaction.
Balanced chemical equation of a reaction is written according to law of conservation of mass.
(b)
Interpretation:
The number of moles of
Concept introduction:
Mass: It is the quantitative measure of a substance. The amount of matter present in substance is expressed as mass. The
Moles: One mole is equivalent to the mass of the substance consists same number of units equal to the atoms present in
From given mass of substance moles could be calculated by using the following formula,
Molar mass: It is obtained by dividing the mass of substance with the amount of substance and the S.I. unit of molar mass is
