What are the coeffients that balance the following skeletal equation?
CH4 + O2 + Cl2 ® HCI + CO

CH4 ---> 2

CL2 > 4

HCL > 8

CO> 2

Explanation:

Equation

CH4 + O2 + Cl2 => HCI + CO

we have to balance it

On LHS  atoms of oxygen is 2  while on RHS it is 1 atom so lets balance oxygen  first

to balance oxygen on RHS we add 2 as coefficient to CO

CH4 + O2 + Cl2 => HCI + 2CO

On RHS  atoms of Carbon is 2  while on RHS it is 1 atom so lets balance Carbon   now

to balance Carbon on LHS we add 2 as coefficient to CH4

2CH4 + O2 + Cl2 => HCI + 2CO

On LHS atoms of hydrogen is 8 so lets balance hydrogen now

to balance hydrogen on RHS we add 8 as coefficient to HCL

2CH4 + O2 + Cl2 => 8HCI + 2CO

On RHS atoms of Cl is 8 while on LHS  atoms of Cl is 2.

To make no of atoms of Cl 8 on LHS we add 4 as coefficient

2CH4 + O2 + 4Cl2 => 8HCI + 2CO

Thus, coefficients are as given below

CH4 ---> 2

CL2 > 4

HCL > 8

CO> 2

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
