For the reaction
3 Ni2+(aq) + 2 Cr(OH)3(s) + 10 OH- (aq) → 3 Ni(s) + 2 CrO42-(aq) + 8 H2O(l) G = +87 kJ/mol
Given:
(Ni2+(aq) + 2 e- → Ni(s)) x 3 Ered = -0.28 V
(CrO42-(aq) + 4 H2O(l) + 3 e- → Cr(OH)3(s) + 5 OH-(aq)) x 2
_____________________________________________________________________________________
3 Ni2+(aq) + 6 e- → 3 Ni(s)
2 CrO42-(aq) + 8 H2O(l) + 6 e- → 2 Cr(OH)3(s) + 10 OH-(aq)
Answer:
2,2,3-trimethyl-pentane
Explanation:
The longest chain is 5 carbons so the parent chain is a pentane. There are two methyl groups coming off the second carbon in the chain and 1 methyl group coming off the 3rd carbon in the chain. In total there are 3 methyl groups, hence we get 2,2,3-trimethyl-pentane.
Answer:
C. The point of contact between the skates and the ice
Explanation:
That is the only point of friction with the ice that provides the ability to complete the move.
salute vs the solvent a solvent is what a salute gets dissolved in
in this case the salute is the chocolate and the solvent is the water
By the process of Nuclear Fission:
1) We Generate Electricity. - If the process is controlled, then we can do this. It's very better way to generate electricity. 'cause of it's many advantages, all nation wants to enhance their electricity production through this mean.
2) We Create explosive. - Again, with the help of nuclear fission we can create certain helpful bombs like Atom Bomb which will help us in war.
Hope this helps!
