1. 1) СН3-СН(СН3)-СН2-СН2-I + KOH -EtOH-> CH3-CH(CH3)-CH=CH2 + KI + H2O
2)
CH3-CH(CH3)-CH=CH2 + HI -> CH3-CH(CH3)-CH(I)-CH3
3) CH3-CH(CH3)-CH(I)-CH2 + KOH -EtOH-> CH3-C(CH3)=CH-CH2 + KI + H2O
4) 3CH3-C(CH3)=CH-CH3 + 2KMnO4 + 4H2O = 3CH3-C(CH3)(OH)-CH2-CH3 + 2MnO2 + 2KOH
2. CH3-CH2-CH2OH + HI -> CH3CH2CH2I + H2O
CH3CH2CH2I + KOH -тут водный наверное, вы в условии ошиблись-> CH3-CH2-CH2ОН + KI
CH3-CH2-CH2ОН -H2SO4> CH3-CH=CH2 + H2O
CH3-CH=CH2 + H2O -> CH3-CH(OH)-CH3
CH3CH(OH)CH3 + CuO -> CH3-C(=O)-CH3 (ацетон) + Cu + H2O
CH3C(=O)CH3 + H2 -Ni-> CH3-CH(OH)-CH3
2HCl+Zn=ZnCl2+H2
CuO+2HCl=CuCl2+H2O
CaCO3+2HCl=CaCl2+CO2+H2O
AgNO3+HCl=AgCl+HNO3

m(ppa Na2CO3)=120 g
W(Na2CO3)=8%
+HCL
----------------------------
V(CO2)-?
m(Na2CO3)=120*8%/100% = 9.6 g
9.6 g X L
Na2CO3+2HCL-->2NaCL+H2O+CO2↑
106 22.4
M(Na2CO3)=106 g/mol , Vm=22.4 L/mol
X=9.6*22.4 / 106=2.03 L
ответ 2.03 л
