Chapter 6.3, Problem 6.8P

(a)

Interpretation Introduction

Interpretation:

The given equation should be balanced and moles associated with nickel should be calculated.

Concept Introduction:

The co-efficient in a balanced chemical equation that tell how many molecules and thus how many moles of each reactant are needed and how many molecules and thus moles of each product are formed.

(b)

Interpretation Introduction

Interpretation:

The moles of ${\text{NiCl}}_2$ formed should be determined in the reaction of $\text{6}\text{.00 mol}$ of $\text{Ni}$ and $\text{12}\text{.0 mol }$ of $\text{HC1}$.

Concept Introduction:

The co-efficient in a balanced chemical equation that tell how many molecules and thus how many moles of each reactant are needed and how many molecules and thus moles of each product are formed.
