Answer 1

6. 2CH₃COOH+Mg(OH)₂ => Mg(CH₃COO)₂ + 2H₂O

CH₃COOH+CaO=Ca(CH₃COO)₂+H₂O

7. C₁₂H₂₂O₁₁+12O₂=12CO₂+11H₂O

n(C₁₂H₂₂O₁₁)=m/M=108/342=0,32 моль

n(CO₂)=n(C₁₂H₂₂O₁₁) х 12 =0,32х12=3,84 моль

V(CO₂)=n x Vm=3,84 x 22,4 = 86 л

8. 2CH3COOH+Ca=(ChH3COO)Ca+H2

n(H2)=V/Vm=11,2/22,4=0,5 моль

n(CH3COOH)=n(H2) x 2= 0,5 x 2 =1 моль

m((CH3COOH)=n x M= 1 x 60 = 60г

W= (m p.p./m р-ну)x100%=33,3%
