Chapter 9, Problem 16E

Interpretation Introduction

Interpretation:

The mass in grams of baking soda which decomposes to give $\text{1}\text{.25}\text{g}{\text{Na}}_{\text{2}}{\text{CO}}_{\text{3}}$ is to be calculated. The stoichiometry type corresponding problem is to be classified.

Concept introduction:

Chemical reactions are represented by chemical equations. In a chemical equation the reactants are represented on the left of the arrow while the products are represented on the right of the arrow.

Stoichiometric coefficient is the number preceding each symbol in a reaction which determines the moles of the reactants and products in the reaction.
