Acceleration= change
-----------
Time
The change in velocity is 4 m/s b/c 7-3=4.
The time taken is 5 s b/c 10-5 = 5.
So its 4/5 which is
0.8 m/s^2.
You're welcome.
Answer:
2.18x10^-9 M
Explanation:
From the question given,
Hydrogen ion concentration, [H+] = 4.59x10^-6 M
Hydroxide ion, [OH-] =?
The hydroxide ion concentration, [OH-] in the solution can be obtained as follow:
[H+] x [OH-] = 1x10^-14
4.59x10^-6 x [OH-] = 1x10^-14
Divide both side by 4.59x10^-6
[OH-] = 1x10^-14 / 4.59x10^-6
[OH-] = 2.18x10^-9 M
