Which of the following hydrocarbons will most likely be found around cows? ethane methane octane decane

Option (b) is the correct answer.

Explanation:

Cows are responsible for producing cow dung which is also known as a source of green energy because it produces bio-gas.

Therefore, it is used as a fertilizer because cow dung produces methane gas and this gas behaves as a stable and renewable source of electricity which is inexpensive.

Therefore, we can conclude that methane is the hydrocarbon that will most likely be found around cows.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
