1) CH3-CH3 = CH2=CH2+H2
2) CH2=CH2+H2O = CH3CH2OH
3) CH3CH2OH+CuO = CH3COH+Cu+H2O
4) CH3COH+2Cu(OH)2 = CH3COOH+Cu2O+2H2O
5) CH3COOH+Cl2 = CH2(Cl)COOH+HCl
6) CH2(Cl)COOH+2NH3 = NH2-CH2COOH+NH4Cl
7) nNH2-CH2COOH = (-NH-CH2-CO-)n+nH2O

1)zno + h2so4 = znso4 + h20
50 * 0.1 = 5
n(h2so4) = 5 /98 = 0.05
n(h2so4)= n(zno)
m(zno) = n* Mr = 0.05 * 81 = 4.05
2) 4al + 302 = 2al203
5* 0.02 = 0.1
5-0.1 = 4.9
n(al) = 4.9/27 = 0.18
n(al) = 0.75n(02) = 0.135
v(o2) = n* Vm = 3.024
