Give balanced chemical equations for the following conversions A, B, and C:

Aluminium carbide reacts with water according to the following equation :
`Al_4C_3 + 12H_2O-> 4Al(OH)_3 + 3CH_4`
1)What mass of aluminium hydroxide is formed from 12g of aluminium carbide?
2) What volume of methane at s.t.p. is obtained from 12g of aluminium carbide?
[Relatively molecular weight of `Al_4Cl_3 = 144; Al(OH)_3 = 78]`
If the relative molecular mass of A is 90, what is the molecular formula of A?
Water can split into hydrogen and oxygen under suitable conditions. The equations representing the change is: 2H2O(I) → 2H2 (g) + O2(g)
Ammonia burns in oxygen and the combustion in the presence of a catalyst may be represented as:
2NH3 (g) +21/2O2 (g) → 2NO (g) + 3H2O (I)
What mass of steam is produced when 1.5 g of nitrogen monoxide is formed?
