The product : Copper oxide

Further explanation

Given

Word equation

Required

The product of the reaction

Solution

The chemical equation can be expressed in terms of:

  • words equation
  • the skeleton equation
  • balanced equation

If we state the word equation above into a chemical equation(with formula)

CuCO₃ ⇒ CuO + CO₂

This reaction is a type of decomposition reaction

AB⇒A+B

Where the copper carbonate is decomposed into copper oxide and carbon dioxide

As we know, in a chemical reaction, the reactants are on the left and the products are on the right

So that the products of this reaction are copper oxide and carbon dioxide and the reactants are copper carbonate
