Question

7. The heating of magnesium carbonate produces

magnesium oxide and carbon dioxide gas. In an
experiment, a student heated 4.2 g of magnesium
carbonate.
• Write a chemical equation for the decomposition
of magnesium carbonate.
• Calculate the mass of magnesium oxide produced (Relative atomic mass : C=12 , O = 16 , Mg = 24)

Answer 1

C=12 , O = 16 , Mg = 24)
