Write there chemical equation 1to 7

Here are the balanced chemical equations for the first 7 reactions, including state symbols:

1. Sodium + water $\rightarrow$ Sodium hydroxide + Hydrogen gas

   $$2\text{Na(s)} + 2\text{H}_2\text{O(l)} \rightarrow 2\text{NaOH(aq)} + \text{H}_2\text{(g)}$$

2. Magnesium + Copper(II) sulfate $\rightarrow$ Magnesium sulfate + Copper

   $$\text{Mg(s)} + \text{CuSO}_4\text{(aq)} \rightarrow \text{MgSO}_4\text{(aq)} + \text{Cu(s)}$$

3. Barium nitrate + Sodium sulfate $\rightarrow$ Barium sulfate + Sodium nitrate

   $$\text{Ba(NO}_3)_2\text{(aq)} + \text{Na}_2\text{SO}_4\text{(aq)} \rightarrow \text{BaSO}_4\text{(s)} + 2\text{NaNO}_3\text{(aq)}$$

4. Zinc + Copper(II) chloride $\rightarrow$ Zinc(II) chloride + Copper

   $$\text{Zn(s)} + \text{CuCl}_2\text{(aq)} \rightarrow \text{ZnCl}_2\text{(aq)} + \text{Cu(s)}$$

5. Sodium phosphate + Potassium hydroxide $\rightarrow$ Sodium hydroxide + Potassium phosphate

   $$\text{Na}_3\text{PO}_4\text{(aq)} + 3\text{KOH(aq)} \rightarrow 3\text{NaOH(aq)} + \text{K}_3\text{PO}_4\text{(aq)}$$

6. Calcium carbonate + Hydrochloric acid $\rightarrow$ Calcium chloride + Carbon dioxide + water

   $$\text{CaCO}_3\text{(s)} + 2\text{HCl(aq)} \rightarrow \text{CaCl}_2\text{(aq)} + \text{CO}_2\text{(g)} + \text{H}_2\text{O(l)}$$

7. Aluminum + Iron(II) sulfate $\rightarrow$ Aluminum sulfate + Iron

   $$2\text{Al(s)} + 3\text{FeSO}_4\text{(aq)} \rightarrow \text{Al}_2\text{(SO}_4)_3\text{(aq)} + 3\text{Fe(s)}$$
