Question

Complete and balance the following equations
(a) CH4 + O2 →
(b) CH4 + CI2 Sunlight →

Answer 1

Answer:

(a) CO2 + H20

(b) HCL + C

second one is incorrect maybe

Answer 2

a)  $CH_{4} + O_{2} ->?$

Balanced Equation:

$CH_{4} + 2 O_{2} -> CO_{2} + H_{2} O$  

b)$CH_{4} + 3Cl_{2} ->?$

Balanced Equation:                     $CH_{4} + 3Cl_{2} -> CH_{3} Cl +3 HCl$

Explanation:

a) $CH_{4} + O_{2} ->?$

$CH_{4} + 2 O_{2} -> CO_{2} + H_{2} O$

when methane reacts  with oxygen forming carbon dioxide  with water

To balance the equation:

C atoms: Balanced with 1 C on both side.

H atoms : On left side there are 4 Hydrogen atoms and  2 Hydrogen atoms on right.put a coefficient 2 in front of the $H_{2} O$

O atoms : There are 2 Oxygen atoms in left side and 4 in right.put a coefficient 2 in front of the $O_{2}$.

b) $CH_{4} + 3Cl_{2} -> CH_{3} Cl +3 HCl$

The above given reaction is said to be chlorination and it is a kind of substitution of hydrogen atoms by other chlorine atoms.
