1. Write the chemical equation for the following:

1. Oxidation of sodium
2. Decomposition of calcium carbonate

Dear Student 

The chemical equation for the following are:

(i) Oxidation of sodium:
      $$\begin{gathered} Na + H_{2}O\to NaOH +\hspace{0.17em}{H}_2 \\ 0 +1 \end{gathered}$$

(ii) Decomposition of calcium carbonate:
      $CaC{O}_3 \stackrel{∆}{\to }CaO + C{O}_2$
