Convert 15 g BaCO3 to moles. moles = grams/molar mass
Using the coefficients in the balanced equation, convert moles BaCO3 to moles HCl.
how many moles of hydrogen chloride would be needed to react completely with 15g of barium carbonate
equation is given:
BaCO3 + 2HCl to BaCl2 + H2O + CO2

it would take 30 grams of HCl to react completely with BaCO3, since it's a 1 to 2 ratio
30 grams of HCl = 1 mole/36 grams
so it's .83 moles of HCl
30 grams of HCl = 1 mole/36 grams
so it's .83 moles of HCl
Margaret gets an A for trying but an F for the answer. Chemicals react by moles, not by grams; therefore, it will NOT take 30 grams HCl nor will it take 0.83 moles HCl. The statement about it being a 1:2 ratio is correct.
