Chapter 4, Problem 4.71SP

Interpretation Introduction

Interpretation:

The net ionic reactions should be written for the given equations.

Concept introduction:

To understand the net ionic equation, an understanding of spectator ions is very important. The spectator ions are the ions which are present in same form in both the reactant and product sides. So, while writing the net ionic equation, these ions are not involved.

Net ionic equations can be written for ionic compounds only.

Given:

1. $S_8(s)+8O_2(g)\to 8S{O}_2(g)$
2. $NiC{l}_2(aq)+N{a}_{2}S(aq)\to NiS(s)+2NaCl(aq)$
3. $2C{H}_{3}C{O}_{2}H(aq)+Ba{(OH)}_2(aq)\to {(C{H}_{3}C{O}_2)}_{2}Ba(aq)+2H_{2}O(l)$

(a)
