Question

Write a balanced equation to show the reaction that occur when;
.a). Caesium react with dilute nitric acid.

b). strontium react with nitrogen.

c). Rubidium reacts with oxygen.

d). magnesium reacts with steam.

e).Slaked lime react with sulphur dioxide gas from the waste gas released by power stations.
Write their state symbols as well.

Answer 1

Here are the balanced equations for each of the reactions along with their state symbols:

a) **Caesium reacts with dilute nitric acid:**
\[
2 \, \text{Cs (s)} + 4 \, \text{HNO}_3 \, \text{(aq)} \rightarrow 2 \, \text{CsNO}_3 \, \text{(aq)} + 2 \, \text{H}_2 \, \text{(g)}
\]

b) **Strontium reacts with nitrogen:**
\[
3 \, \text{Sr (s)} + \text{N}_2 \, \text{(g)} \rightarrow \text{Sr}_3\text{N}_2 \, \text{(s)}
\]

c) **Rubidium reacts with oxygen:**
\[
4 \, \text{Rb (s)} + \text{O}_2 \, \text{(g)} \rightarrow 2 \, \text{Rb}_2\text{O} \, \text{(s)}
\]

d) **Magnesium reacts with steam:**
\[
\text{Mg (s)} + \text{H}_2\text{O (g)} \rightarrow \text{MgO (s)} + \text{H}_2 \, \text{(g)}
\]

e) **Slaked lime reacts with sulfur dioxide gas:**
\[
\text{Ca(OH)}_2 \, \text{(aq)} + \text{SO}_2 \, \text{(g)} \rightarrow \text{CaSO}_3 \, \text{(aq)} + \text{H}_2\text{O (l)}
\]

This provides the balanced equations with appropriate state symbols for each reaction.
