Question

1. ch2=ch2+br2=2. c2h6+o2=​

Answer 1

Ответ:

Объяснение: извини, могу помочь только 2. C2H6+O2=CO2⬆️+H2O реакция горения этана.

Answer 2

Первая реакция: Галогенирование
CH2=CH2 + Br2 => CH2Br-CH2Br
Этен + бром -> дибромэтан

Вторая реакция: Горение
2C2H6 + 7O2 => 4CO2 + 6H2O
Этан + кислород -> Углекислый газ + вода

Запомни: Когда углеводороды горят, то продуктом реакции всегда углекислый газ и вода!

Answer 3

It seems like you're trying to write chemical reactions. Let me help you balance these equations:

1. The first equation appears to be a reaction between chlorine gas (Cl2) and bromine gas (Br2) to form some product. Assuming it forms a compound, the balanced equation would look like this:

   Cl2 + Br2 → 2 ClBr

2. The second equation represents the combustion of ethane (C2H6) with oxygen (O2) to form carbon dioxide (CO2) and water (H2O). Here's the balanced equation:

   C2H6 + 7 O2 → 2 CO2 + 3 H2O
