Answer:
2 CrO42- + 3N2O + 10 H+ -----> 2Cr3+ + 6NO + 5H2O
Explanation:
2 CrO42- + 3N2O + 10 H+ -----> 2Cr3+ + 6NO + 5H2O
Oxidizing agent: -----------------------------> CrO42-
Reducing agent: ----------------------------> N2O
explanation:
in CrO4-2 oxdiation state of Cr = +6
in Cr+3 oxidation state = +3
+6 oxidation state changed from +3 it is reduction .
so CrO4-2 is oxidizing agent
atomatically
N2O should be reducing agent
The answer is electrical energy
So, what's your question..?. You just gave options..
The production of is . Converting mass into kg,
1 ton=907.185 kg, thus,
Thus, production of will be .
The specific volume of is .
Volume of produced per day can be calculated as:
Putting the values,
Thus, volume of produced per year will be:
Thus, in 4 year volume of produced will be:
The correct answer is C. Litmus Indicator
