What is formed when you react HCl and MgCO3?

Answer 1

Remember the general reaction eq'n for all acids reacting with carbonates.

Acid + Carbonate = Salt + Water + Carbon dioxide.

So for HCl & MgCO3

2HCl(aq) + MgCO3(s) = MgCl2(aq) + H2O(l) + CO2(g)

In Words.

Two molar ratios of hydrochlorice acid react with one molar ratio of magnesium carbonate to produce one molar ratio each of magnesium chloride(salt) plus water plus carbons dioxide.

Answer 2

Carbonates react with acids to produce salt + water + carbon dioxide.

Hydrochloric acid produces chloride salts.

In this case:

Magnesium carbonate + hydrochloric acid --> magnesium chloride + water + carbon dioxide

As a symbol equation:

MgCO3 + HCl --> MgCl2 + H2O + CO2

Balancing (ensure the same number of atoms are on both sides of the arrow):

MgCO3 + 2HCl --> MgCl2 + H2O + CO2

Answer 3

When you react hydrochloric acid (HCl) with magnesium carbonate (MgCO3), carbon dioxide gas (CO2) is produced due to the decomposition of MgCO3, which results in the formation of magnesium chloride (MgCl2) and water (H2O).

Answer 4

MgCO3(s) + 2HCl(aq) --> MgCl2(s) + H2O(l) + CO2(g)

Answer 5

metal + acid ---> salt + hydrogen gas

Magnesium is a metal. Therefore,

Magnesium + acid ---> a magnesium salt + hydrogen gas

Answer 6

magnesium chloride
