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.

Answer 1

Here are the balanced chemical equations for the reactions you specified:

a) **Caesium reacts with dilute nitric acid**:
\[
\text{Cs} + 4 \text{HNO}_3 \rightarrow \text{CsNO}_3 + 2 \text{H}_2\text{O} + 2 \text{NO}_2
\]

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

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

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

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

Each equation is balanced in terms of both mass and charge.
