Write the balanced equation for calcium carbonate reacts with dillute hydrochloric acid to form calcium chloride water and carbon dioxide

Balance the Chemical Equation for the reaction of calcium carbonate with hydrochloric acid: CaCO3+ HCl -> CaCl2 + CO2 + H2O.
H doesn't balance. Cl doesn't balance.
CaCO3 + 2HCl -> CaCl2 + CO2 + H2O.
To write the balanced equation for the reaction between calcium carbonate and dilute hydrochloric acid, follow these steps:
Step 1: Write down the chemical formulas of the reactants.
- Calcium carbonate: CaCO3
- Hydrochloric acid: HCl
Step 2: Determine the products formed during the reaction.
- Calcium chloride: CaCl2
- Water: H2O
- Carbon dioxide: CO2
Step 3: Write the balanced equation by placing the reactants on the left side and the products on the right side of the equation.
CaCO3 + 2HCl → CaCl2 + H2O + CO2
In the balanced equation, the number of atoms on each side of the reaction arrow should be the same. Therefore, we need 2 moles of hydrochloric acid to react with 1 mole of calcium carbonate to produce 1 mole of calcium chloride, 1 mole of water, and 1 mole of carbon dioxide.
