(a)

Interpretation Introduction

Interpretation:

The type of change is to be identified when carbon dioxide reacts with water to form hydrogen carbonate.

${\text{CO}}_2(g)+{\text{H}}_2\text{O}(l)\_\to {\text{H}}_2{\text{CO}}_3(aq)$

(b)

Interpretation Introduction

Interpretation:

The type of change is to be identified when ${\text{H}}_2\text{O}(g)$ changes to ${\text{H}}_2\text{O}(l)$ .

${\text{H}}_2\text{O}(g)\to {\text{H}}_2\text{O}(l)$

(c)

Interpretation Introduction

Interpretation:

The type of change is to be identified when $\text{HOCN}(g)$ changes to $\text{HCNO}(g)$ .

$\text{HOCN}(g)\to \text{HCNO}(g)$
