200g solutie de acid actic de concentratie 40% reactioaneaza stoechimetric cu carbonatul de calciu. a) calculeaza columul de CO2 obtinut, masurat in conditii normale.
md=ms*c/100=200*40/100=80 g 2 CH3COOH + CaCO3 ----> (CH3COO)₂Ca + H2O + CO2 2 * 60 g acid.........22,4 l CO2 80 g acid...............x l CO2 x = 14,93 litri CO2 V in cond normale = 22,4 litri;masa acid = 60g/mol=4+24+32
