Chapter 10, Problem 9PE

Interpretation Introduction

Interpretation:

The number of moles of lead $\left(\text{II}\right)$ iodide that will precipitate if $1.10$ moles of sodium iodide and $0.761$ moles of lead $\left(\text{II}\right)$ nitrate are dissolved in the same beaker of water is to be calculated. The reactant whose number of moles will remain unreacted is to be stated. The number of moles of the reactant that will remain unreacted is to be stated.

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. The ratio of moles is termed as mole ratio. In stoichiometry problems, the reactant that controls the amount of the product formed is known as the limiting reactant.
