Răspuns:1.11gCaCl2; 0.44gCO2
Explicație:2HCl+CaCO3= CaCl2+CO2+H20
c=md.100/ms=>md=3.65.100/500=0.73gHCl
n=m/M=0.73/36.5=0.02moli HCl
2moli HCl-------1mol CaCl2
0.02---------------0.01=> m=n.MCaCl2=0.01 . 111=1.11g CaCl2
2moli HCl-------1molCO2
0.02------------0.01molCO2
m=n.MCO2=0.01 . 44=0.44g CO2
