An analyst has two separate beakers containing dilute sulfuric acid.
They add a spatula measure of magnesium carbonate powder, MgCO3\text{MgCO}_3MgCO3, to the first beaker, and a strip of magnesium ribbon, Mg\text{Mg}Mg, to the second beaker.
Explain what the analyst would observe in each beaker and how they could chemically test the gas produced in each case to confirm its identity.
Your answer must include word equations for both chemical reactions.
