Hey there!
HCN + CuSO₄ → H₂SO₄ + Cu(CN)₂
Balance CN.
1 on the left, 2 on the right. Add a coefficient of 2 in front of HCN.
2HCN + CuSO₄ → H₂SO₄ + Cu(CN)₂
Balance H.
2 on the left, 2 on the right. Already balanced.
Balance SO₄.
1 on the left, 1 on the right. Already balanced.
Balance Cu.
1 on the left, 1 on the right. Already balanced.
Our final balanced equation:
2HCN + CuSO₄ → H₂SO₄ + Cu(CN)₂
Hope this helps!
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
Generally, the top elements in group 16 will have a charge of -2, although the entire group isn't standardized.
