Chapter 22, Problem 5PS

a)

Interpretation Introduction

Interpretation: The given equations are to be balanced.

Concept introduction:

• Transition elements: It contains either d sub shells which are incomplete or that readily lose electrons to get incomplete d subshell. It includes elements in group 1B and 3B through 8B.
• Chemical equation is the representation of a chemical reaction where the reactants and products of the reactions are represented on left and right side of an arrow respectively by using their respective chemical formulas. It follows conservation law of mass where the number of atoms of each element is equal for reactants and products.
