Answer : The correct option is, KCl is the salt and KOH is the base.
Explanation :
Neutralization reaction : It is a type of reaction in which an acid react with a base to give a salt and water as a product.
The balanced chemical reaction is :
The given balanced reaction is an example of neutralization reaction in which KOH is a base and HCl is an acid when both combine the it gives KCl as a salt and as a water.
Hence, the correct option is, KCl is the salt and KOH is the base.
Answer : The correct option is, (E) 6 moles.
Explanation : Given,
Moles of nitrogen = 2 moles
The given balanced chemical reaction is:
From the balanced chemical reaction we conclude that,
As, 1 mole of nitrogen gas react with 3 moles of hydrogen gas
So, 2 mole of nitrogen gas react with moles of hydrogen gas
Therefore, the number of moles of hydrogen gas needed to react with 2 moles of nitrogen gas is, 6 moles.
