Question

write down the balanced chemical equation for the following reaction (a) zinc carbonate -- zinc oxide + carbon dioxide (g) (b) aluminium (s) + chlorine (g) -- aluminium chlorine (s) (c) magnesium (s) + water (l) heat magnesium hydroxide (l) + hydrogen (g)​

Answer 1

Explanation:

a)

ZnCO3 (s)→ZnO (s) + CO2 (g)

b)2 Al(s) + 3 Cl2(g) → 2 AlCl3(s )

c)Mg+2H 2O→Mg(OH) 2+H 2

Magnesium reacts with hot water to form magnesium hydroxide and hydrogen.
