Question

Hydrochloric acid and calcium carbonate react in the same way that baking soda and vinegar do. Write equations for the two reactions that occur when these compounds react.

2HCl + CaCO3 = CaCl2 + CO2 + H2O
CaCO3 + 2HCl = CaCl2 + H2CO3

Answer 1

`2HCl + CaCO_3 ---> CaCl_2 + CO_2 + H_2O`

`CH_3COOH + NaHCO_3 ---> CH_3COONa + CO_2 + H_2O`

Step-by-step explanation:

Hydrocholoric acid is written as HCl

Calcium carbonate is written as
`CaCO_3`

For a balanced equation, 2 moles of Hydrochloric acid reacts with 1 mole of calcium carbonate to give one mole of calcium chloride, 1 mole of carbon dioxide and 1 mole of water respectively.

`2HCl + CaCO_3 ---> CaCl_2 + CO_2 + H_2O`

Baking soda is written as
`NaHCO_3`

Vinegar is written as
`CH_3COOH`

1 mole of vinegar reacts with 1 mole of baking soda to give 1 mole of sodium acetate, one mole of carbon dioxide and 1 mole of water respectively.

`CH_3COOH + NaHCO_3 ---> CH_3COONa + CO_2 + H_2O`
