Answer 1

Ответ:

Объяснение:

1)H2C=CH2+CI2→CH2Br-CH2Br

2) HC≡CH+H2→CH3-CH3

3) C5H12+8O2→ 5CO2+6H2O

4) C2H6+CI2 →C2H5CI+HCI( на свету)

Answer 2

It seems like you've provided a list of chemical reactions with some missing information. I'll do my best to complete them for you:

1. C2H4 + Cl2
   This is the reaction between ethene (C2H4) and chlorine (Cl2) gas. It's a halogenation reaction where one or more hydrogen atoms in the hydrocarbon are replaced by halogen atoms. The reaction is initiated by light (hv):

   C2H4 + Cl2 → C2H4Cl2

2. C2H2 + H2
   This is the reaction between acetylene (C2H2) and hydrogen (H2) gas. This is an addition reaction:

   C2H2 + H2 → C2H4

3. C5H12 + O2
   This is the combustion of pentane (C5H12) with oxygen (O2) gas. In a complete combustion, it produces carbon dioxide and water:

   C5H12 + 8O2 → 5CO2 + 6H2O

4. C2H6 + Cl2hv
   This is the reaction between ethane (C2H6) and chlorine (Cl2) gas, initiated by light (hv). This is a free radical substitution reaction:

   C2H6 + Cl2 → C2H5Cl + HCl
