B) Consider the following reactions:
1) 2NO2-N204
ii) 2Cro42- + 2H+
Cr2O72- + H2O
Identify which of the following reactions are redox reactions. Justify your answer.

i believe the answer is true.

the answer is c.the valence of the atoms combine .

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 .
