Hey there!
CaCO₃ + HCl → H₂O + CO₂
This equation is impossible to balance.
There must be a mistake in the writing of the equation.
There is Ca in the reactants, but there is no Ca in the products.
The law of conservation of mass states that the products must be equal to the reactants, which means this equation cannot follow the law of conservation of mass.
Therefore, this equation is impossible to balance.
Hope this helps!
