Question

write balanced chemical equation

Answer 1

Answer:

1) When carbon is burned in air, it forms carbon dioxide gas and releases a large amount of heat and some light:

C + O2 → CO2 + Heat + Light

2) When green copper carbonate is heated, it decomposes forming copper oxide & Carbon dioxide .

CuCO3 (s)———-> CuO(s) + CO2(g)

3) Zinc reacts with dilute HCl to form zinc chloride and hydrogen gas.

Zn+2HCl→ZnCl2 + H2 ↑

4) The product formed when AgNO3 reacts with NaCl is AgCl and NaNO3. So, we can write the equation:

AgNO3(aq) + NaCl(aq) = AgCl(s) + NaNO3(aq)
