Помогите пожалуйста решить уравнения по Химии

103:

C2H2 + H2 = C2H4

C2H4 + HOH (t,H+)= C2H5OH

X = C2H4

104:

CO + 2H2 = CH3OH

2CH3OH + 2Na = 2CH3ONa + H2

X1 = CH3OH

X2 = Na

105:

C2H6 + Cl2 (hv)= C2H5Cl + HCl

C2H5Cl + NaOH(вод)= C2H5OH + NaCl

X1 = Cl2

X2 = NaOH

106:

2C6H5OH + 2Na = 2C6H5ONa + H2

2C6H5ONa + CO2 + H2O = 2C6H5OH + Na2CO3

X = C6H5ONa

107:

C6H5ONa + HCl = C6H5OH + NaCl

C6H5OH + 3H2 (Ni)= C6H11OH

X1 = HCl

X2 = C6H11OH
