<span>Ans- bond with the highest bond energy is for ( C=C \rightarrow 620 (kJ/mol)
N=N \rightarrow 418 (kJ/mol)
Si=O \rightarrow 452 (kJ/mol)
O=O \rightarrow 498.7 (kJ/mol)
C=N \rightarrow 615 (kJ/mol)
C=C \rightarrow 620 (kJ/mol)</span>
Answer:
A geologist would observe how the material that the sculpture is made out of reacts to the acid.
Answer:
B. oxidation; reduction
Explanation:
A voltaic cell is electro-chemical cell in which chemical energy is converted into electrical energy.
1. This cell utilizes chemical reaction to generate electric.\
2. there two electrode anode and cathode
3. At Anode oxidation occurs
4. At cathode reduction occurs
5. chemical is present in the cell which is electrolyte which completes the circuit of the voltaic cell.
- oxidation is the process in which there is loss of electrons
- Reduction is the process in which there is gain of electrons
___________________________________________________
Based on above discussion
At anode oxidation takes place
At cathode reduction takes place.
Hence, correct option is B. oxidation; reduction
