The missing labels are:
- CuCO₃(s), H₂SO₄(aq): reactants.
- +: plus sign.
- CuSO₄(aq), H₂O(l), CO₂(g): products.
- (s): solid.
- (aq): aqueous.
- (l): liquid.
- (g): gaseous.
<h3>What is a chemical equation?</h3>
It is a way to represent a chemical reaction.
Let's consider the following chemical equation.
CuCO₃(s) + H₂SO₄(aq) → CuSO₄(aq) + H₂O(l) + CO₂(g)
The missing labels are:
- CuCO₃(s), H₂SO₄(aq): reactants. They are on the left side of the equation.
- +: plus sign. It separates substances.
- CuSO₄(aq), H₂O(l), CO₂(g): products. They are on the right side of the equation.
- (s): solid.
- (aq): aqueous.
- (l): liquid.
- (g): gaseous.

When aqueous solutions of Potassium Carbonate and Copper Nitrate are mixed, the potassium will displace the copper, as it is more reactive, and Potassium Nitrate and Copper Carbonate will be formed.
The equation for this reaction is (ignoring state symbols):
K₂CO₃ + Cu(NO₃)₂ ⇒ 2KNO₃ + CuCO₃
