Answer:
"2.48 mole" of H₂ are formed. A further explanation is provided below.
Explanation:
The given values are:
Mole of Al,
= 3.22 mole
Mole of HBr,
= 4.96 mole
Now,
(a)

Answer:
Selenium hexachloride is SeCl6.
Explanation:
Answer:
-36.67 KJ
Explanation:
Now, we ,must find the E°cell as follows;
E°cell= E°cathode - E°anode
E°cathode= -0.25 V
E°anode = - 0.44 V
E°cell= -0.25 -(- 0.44) = 0.19 V
Equation of the reaction; Ni2+ (aq) + Fe(s) → Ni(s) +Fe2+ (aq)
Hence, n=2, there were two electrons transferred.
ΔG=-nFE°cell
ΔG= -(2 * 96,500 * 0.19)
ΔG= -36670 J
ΔG= -36.67 KJ
