Determine if the following half reactions are oxidation or reduction. 1. Al ⇒ Al3+ + 3e-
2. Cu2+ + 2e- ⇒ Cu
3. MnO4- + 5e- + 8H+ ⇒ Mn2+ + 4H2O
4. F2 ⇒ 2F- + 2e-

Explanation:

Determine if the following half reactions are oxidation or reduction.

1. Al ⇒ Al3+ + 3e-

2. Cu2+ + 2e- ⇒ Cu

3. MnO4- + 5e- + 8H+ ⇒ Mn2+ + 4H2O

4. F2 ⇒ 2F- + 2e-

ans A

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
