Based on the balanced chemical equation for the preparation of malachite, what is the composition of the bubbles formed when sodium carbonate is added to the solution of copper sulfate?

Carbon Dioxide = CO2

Explanation:

The synthesis of Malachite is seen in the chemical formula:

CuSO 4. 5H2O (aq) + 2NaCO3 (aq) - -> CuCO 3 Cu (OH) 2 (s) + 2Na 2 SO 4 (aq) + CO 2 (g) + 9H 2 O (l)

The bubbles mentioned in the question hints that our interest is the compounds in their gseous phase (g).

Upon examining the chemical equation, only CO2 is in the gaseous state and hence the only one that can be formed as bubbles,
