Answer:
Both are only physical changes.
Explanation:
Nothing about the objects chemically change, and they remain the same.
Their changes arent due to heating/cooling.
Answer:
Oxidizing agent - CrO4^2-
Reducing agent- N2O
Explanation:
Let us look at the equation closely;
CrO4^2- (aq) + 3N2O(g) ------------> Cr^3+ (aq) + 3NO(g) [acidic]
The reduction half equation is;
CrO4^2- (aq) + 3e -------->Cr^3+ (aq)
Oxidation half equation is;
3N2O(g) ------>3 NO(g) +3 e
Note that the oxidizing agent participates in the reduction half equation while the reducing agent participates in the oxidation half equation as seen above.
A) releasing CO2 that dissolves and forms acid in the oceans (i think i'm sorry if its wrong)
