<u>Answer:</u> The relation between the forward and reverse reaction is 
<u>Explanation:</u>
For the given chemical equation:

The expression of equilibrium constant for above equation follows:
.......(1)
The reverse equation follows:

The expression of equilibrium constant for above equation follows:
.......(2)
Relation expression 1 and expression 2, we get:

Hence, the relation between the forward and reverse reaction is 
Answer:
41.66 mL of 12.0 M sulfuric acid are needed.
Explanation:
Concentration of sulfuric acid solution taken =
Volume of the 12.0 M Solution = 
Concentration of required solution = 
Volume of required 1.00 M solution = 
(Dilution)

41.66 mL of 12.0 M sulfuric acid are needed.
The freezing point and the boiling point of a solvent when a non-volatile solute is dissolved in it decrease and increase respectively.
Answer:
B
Explanation:
Hydrogen is synthesized to water by adding Oxygen.
Hydrogen is oxidised to water by combustion ( burning in presence of oxygen).
Answer:
