Question

7. MgCO3 + HCl → MgCl₂ + H₂CO3​

Answer 1

Объяснение:

MgCO3 + 2HCI = H2CO3 + MgCI2

Answer 2

The chemical equation you've written represents a reaction between magnesium carbonate (MgCO3) and hydrochloric acid (HCl) to produce magnesium chloride (MgCl2) and carbonic acid (H2CO3). However, carbonic acid is unstable and readily decomposes into water (H2O) and carbon dioxide (CO2). Here's the balanced chemical equation for the reaction:

MgCO3 + 2HCl → MgCl2 + H2O + CO2

In this balanced equation, you can see that one molecule of magnesium carbonate reacts with two molecules of hydrochloric acid to produce one molecule of magnesium chloride, one molecule of water, and one molecule of carbon dioxide.
