Answer: Combustion is also known as burning, and the substance that burns is usually referred to fuel. The products of a complete combustion reaction include carbon dioxide (CO2) and water vapor (H2O).
Explanation:
Answer:
Reaction will proceed towards forward direction.
Explanation:
Balanced reaction: 
Reaction quotient (
) for this reaction is represented as:
![Q_{c}=\frac{[COCl_{2}]}{[CO][Cl_{2}]}](https://tex.z-dn.net/?f=Q_%7Bc%7D%3D%5Cfrac%7B%5BCOCl_%7B2%7D%5D%7D%7B%5BCO%5D%5BCl_%7B2%7D%5D%7D)
Here, [CO] = [
] = 0.010 M and [
] = 0.070 M
So, 
= 700
As > 
therefore reaction will proceed towards forward direction i.e. more will be produced.
Br + Br -> Br2 (covalent bond)
<span>forming of bonds releases energy, since the Br's are at a lower energy state as Br2
Answer is #3</span>
