Какой объем газа получается при взаимодействии 0.5 моля карбоната кальция с избытком соляной кислоты

Ответ

 0,5 моль                                          Х л

 CaCO3   +   2HCl  =  CaCl2     +     CO2    +   H2O

n = 1 моль                                     n = 1 моль

                                                    Vm = 22,4 л/моль

                                                    V = 22,4 л

0,5 моль СаСО3    -     Х л СО2

1 моль СаСО3      -      22,4 л СО2

V(CO2) = 0,5 * 22,4 / 1 = 11,2 л
