calcium carbonate react with hydrochloric acid solution to form calcium chloride solution water and carbon dioxide. find the percent yield of carbon dioxide if 3.65g is collected when 10.0g of marble reacts.​

CaCO3+2HCl→CaCl2+H2O+CO2

You have to find which is limiting first, we take 10g of marbles10g marbles×1 mol marbles/40+12+3(16)g marbles×1 mol CO2/1 mol marbles=0.4 mol CO2

Then0.4 mol CO2 ×12+2(16)g CO2/1 mol CO2=17.6g of CO2

Based on theoretical calculations, you should get 17.6g of CO2,  but it turns out that you only have 3.65g of CO2 collected, so,3.65g17.6g×100=20.7 percent

im pretty sure its b

12 is it do you think so
