1. \(AlCl_3+3NaOH\xrightarrow[]{}Al\left(OH_3\right)\downarrow+3NaCl\)

2. \(4K+O_2\xrightarrow[]{t^\circ}2K_2O\)

3. \(4P+5O_2\xrightarrow[]{t^{\circ}}2P_2O_5\)

4. \(P_2O_5+3H_2O\xrightarrow[]{}2H_3PO_4\)

5. \(2Al+3H_2SO_4\xrightarrow[]{}AL\left(SO_4\right)_3+3H_2\)

6. \(CaH_{2a+1}OH+\dfrac{3a}{2}O_2\xrightarrow[]{t^\circ}aCO_2+\left(a+1\right)H_2O\)
