Question

If 20.0 grams of CaCo3 is treated with 20.0 grams of Hcl , how many grams of Co2 will be produced ?
what is the limiting reagent?

Answer 1

(1) write a balanced equation
(2) find which has the least number of moles

moles= mass/molar mass

(3) use the coefficients from the balanced equation to relate the moles of limiting reagent to the moles of CO2

aA + bB <-> cC

Moles of A/a= Moles of C/c

then convert mols back to grams using, once again, moles=mass/molar mass

Answer 2

can u write balanced equation
