Question

. Translate the following statement into chemical equations and then

balance it:

a) Aluminium hydroxide reacts with sulphuric acid to form

aluminium sulphate and water.

b) Magnesium carbonate reacts with hydrochloric acid to produce

magnesium chloride, carbondioxide and water.
​

Answer 1

Answer:

a) Aluminium hydroxide reacts with sulphuric acid to form  aluminium sulphate and water : 2Al(OH)3 + 3H2SO4 → Al2(SO4)3 + 6H2O

b) Magnesium carbonate reacts with hydrochloric acid to produce  magnesium chloride, carbon dioxide and water : MgCO3(s) + 2 HCl(aq) → MgCl2(aq) + CO2(g) + H2O(l)

​

Answer 2

Answer:

2Al(OH)3+3H2SO4---------Al2(SO4)3+6H2O

MgCl2(aq)+Co2(g)+H2O(I)
