Answer 1

Answer:

CaCO3(s)+73g2mol2HCl(aq.)→CaCl2(aq.)+H2O(l)+44g1molCO2(g)

Let CaCO3(s) be completely consumed in the reaction. 

∵100gCaCO3 give 44gCO2

∴20gCaCO3 will give 10044×20gCO2=8.8gCO2

Let HCl be completely consumed.

∵ 73 g HCl give 44 g CO2

∴ 20 gHCl  will give 7344×20gCO2=12.054gCO2

Since, CaCO3 gives least amount of product CO2, hence CaCO3
