Answer:
0.260 Celsius
Explanation:
q =c x m x (T2-T1)
c - specific heat of water 4.186 J/g.C
T2-T1 = q /(c x m) = 0.959 /(4.186 x 0.88) = 0.959/3.68 =0.260 C
(A.) Nickel and oxygen reacting chemically could create a compound. (Most likely some sort of oxide)

In other words, the point at which the moles of both solutions are the same.
we match these equations and find the concentration of KOH
