To balance a chemical equation count the number of atoms on both sides of the reaction and equalise them by adding suitable coefficients.
Balanced equation for these reactions are,
2Al(OH)3 + 3H2SO4 ------> Al2(SO4)3 + 6H2O
Al(OH)3 + 3HCl -----> AlCl3 + 3H2O
C2H6O + 3O2 -----> 2CO2 + 3H2O
Mg + 2HCl --------> H2 + MgCl2
