To solve the problem of determining the percentage of `CaCO3` and `MgCO3` in a mixture weighing `1.84 g`, which leaves a residue of `0.96 g` upon heating, we can follow these steps: ### Step 1: Understand the Reactions When `CaCO3` and `MgCO3` are heated, they decompose as follows: - `CaCO3 (s) → CaO (s) + CO2 (g)` - `MgCO3 (s) → MgO (s) + CO2 (g)` From these reactions, we see that the carbonates decompose to form their respective oxides and release carbon dioxide gas. ...
