Answer:
The molarity of the diluted HCl solution: <u>M₂ = 0.045 M</u>
Explanation:
To find- the molarity of the diluted HCl solution (M₂)
Given- <u>For original HCl solution</u>-
Molarity: M₁ = 1.5 M, Volume: V₁ = 60.0 ml = 0.06 L (∵ 1L = 1000 mL)
Then this original solution is diluted to a volume of 2 L
Thus <u>for the diluted HCl solution</u>-
The Volume of the diluted HCl solution: V₂ = 2 L
<u>So the Molarity of the diluted HCl solution (M₂) can be calculated by the </u><u><em>dilution equation:</em></u>
<u>Therefore, the molarity of the diluted HCl solution: M₂ = 0.045 M</u>
Answer: Option (b) is the correct answer.
Explanation:
Since energy of reactants is less than the energy of products. Therefore, it means energy is absorbed during the reaction.
As the energy required to break the bonds in the reactants is greater than the energy released when products are formed.
Therefore, it is an endothermic reaction.
Thus, we can conclude that the statement, it is endothermic because the energy required to break bonds in the reactants is greater than the energy released when the products are formed is correct.
