1.) single replacement reaction. Hope this helps you.
By nuclear fusion of hydrogen nuclei into Helium
<span>Hydrolysis is the breaking down of bonds when water is involved in the reaction. </span>The net reaction for the hydrolysis of water yields hydrogen ions and hydroxide ions because these ions are dissociated upon solvolysis. This means they are completely dissolved and transformed into ions thereafter.
There are several information's already given in the question. Based on the information's provided, the answer can be easily deduced.
V1 = 25 ml
= 25/1000 liter
= 0.025 liter
V2 = 18 ml
= 18/1000 liter
= 0.018 liter
M2 = 1.0 M
M1 = ?
Then
M1V1 = M2V2
M1 = M2V2/V1
= (1 * 0.018)/0.025
= 0.72 M
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the first option or option "A". I hope that this is the answer that has actually come to your help.
