The best statement that in reality the best way to describe this would be "the caco3 is a reactant; it is present before the reaction occurs.". We can see this as it was noted in the first part of this equation, "CaCO3 + 2HCl →" would show that it would be positive, and also this would be a reactant, and also for the second part of the equation, we see also how "aCl2 + CO2 + H2O" was always going to be present before the reaction would then occur.This would, therefore, allow us to understand this equation clearly, and preparation to get to the point of what this really means.
