Question

Write down the balanced chemical equations for the following reactions.
a) Zinc Carbonate(s) → Zinc Oxide + Carbon Dioxide(g)
b) Aluminium(s) + Chlorine(g) → Aluminium Chloride(s)
c) Magnesium(s)+ Water(l) Heat → Magnesium Hydroxide(l) + Hydrogen(g).




​

Answer 1

Answer:

a) ZnCO3 ---> ZnO + CO2

So, this equation is already Balanced

b) Al + C2 ---> AlCl3

Now to balance this equation,

2[Al] + 3[C2] ---> 2[AlCl3]

c) Mg + H20 + Heat ---> Mg(OH)2 + H2

Balancing the skeletal equation,

Mg + 2H20 + Heat ---> Mg(OH)2 + H2
