M(CO2) = 11 т = 11000 кг = 11000000 г
n(CO2) = m/M = 11000000/44 = 250 000 моль
V(CO2) = n*Vm = 250000*22.4 = 5600000 л
1)
а) S + O2 = SO2
б) SO2 + H2O = H2SO3
в) H2SO3 + Ca(OH)2 = 2H2O + CaSO3
2)
а) 4P + 5O2 = P2O5
б) P2O5 + 3H2O = 2H3PO4
в) H3PO4 + 3KOH = K3PO4 + 3H2O
3)
а) Fe2(SO4)3 + 6NaOH = 2Fe(OH)3 + 3NaSO4
б) 2Fe(OH)3 = (при температуре) Fe2O3 + 3H2O
в) Fe2O3 + 6HCl = 2FeCl3 + 3H2O
