Answer
The balanced chemical equation will hence be
Explanation
For this reaction, we complete the equation by equating reactants and products accurately using coefficients derived from the atoms' stoichiometry in their corresponding substances."The copper molecule reacts with one molecule of sulfuric acid (H₂SO₄), and in the product, we have one molecule of copper sulfate copper (II) sulfate so, on the reactive side, we need one molecule of sulfuric acid as well.""There's one CO₂ molecule, so on the reactant side, we need a carbonate ion effectively has CO₂ in water, so we need one molecule of copper carbonate."Finally, there's water on the products' side, which results from the reaction between hydroxide ions and acid protons. But, it's currently missing from the products, so we will need to account for two hydrogen atoms produced through the decomposition of sulfuric acid.Accounting for all the atomic mechanics, the complete and balanced chemical equation for this reaction should be:
Now let's simplify according to stoichiometric coefficients, which results in no change, hence no numerical multiplier needed, so the equation stays as is.
