Answer:
USe this Nernst equation and find your required answer
Explanation:
E = E0 - [0.0592 /n ] log [Cd+2]/[Co2+]
Wher Eo is +0.120 V
[Cd+2] =0.1
[Co2+] = 0.001
n is number of electons transfered int he process and in your case it is = 2
E= 0.120- 0.0296 * log 100
= ........ V
<h2>Answer </h2>
Some mass changes into energy
<u>Explanation </u>
Some mass changes into energy are true about both nuclear fusion and nuclear fission. These both reactions produce large amounts of energy. Nuclear fusion is the process in which two light nuclei combine to form a larger nucleus. On the other hand, nuclear fission is reverse in which a heavy nucleus breaks into two light nuclei. Nuclear decay and transmission are also types of nuclear reactions. The matter is not destroyed in nuclear reactions.

Answer:
100ml of a stock 50% KNO3 solutions are needed to prepare 250ml of a 20% KNO3 solution.
Explanation:
In the given question it is mentioned that
S1=50%
V2=250ml
S2= 20%
We all know that
V1S1=V2S2
∴V1= V2×S2÷S1
∴V1= V2S2×1/S1
∴V1= 250×20÷50
∴V1= 100ml
