Question
Chapter 3, Problem 3.61QP
Interpretation Introduction
Interpretation:
The law based in stoichiometry is to be determined and the need of balanced equations in solving stoichiometric problems should be explained.
Concept introduction:
- Chemical equation is the representation of a
chemical reaction , in which the reactants and products of the reactions are represented left and right side of an arrow respectively by using their respective chemical formulas. - Stoichiometry of a chemical reaction is the relation between reactants and products of the reaction and it is represented by the coefficients used for the reactants and products involved in the chemical equation.
- Balanced chemical equation of a reaction is written according to law of conservation of mass.
