In Methane, we have 1 carbon atom combining with 4 hydrogen atoms.
It can also be said as
1 mole C + 4 mole of H = CH₄
These atoms combine together to give us 1 mole of CH₄
In the question given, we have 1 mole of carbon and 4 moles of hydrogen.
However, the equation for the formation of CH₄ is quite different as it is formed by hydrogenation of ethyne or ethene.
[tex]\begin{gathered} C_2H_2+3H_2\rightarrow2CH_4 \\ C_2H_4+2H_2\rightarrow2CH_4 \end{gathered}[/tex]The above equation are some of the known ways to which methane is formed.
From the explanation above, we have 1 atom of C and 4 atoms of H
