These statements describe three different reactions.
2 answers:
Answer: Option (b) is the correct answer.
Explanation:
When an atom shares electrons with another atom then it results in the formation of covalent bond.
Whereas when an atom transfer electrons from one atom to another then it results in the formation of ionic bond.
When nucleus of an atom splits then it represents nuclear fission reaction and energy is released during this process.
For example,
Therefore, we can conclude that out of the given options, the nucleus of an atom is split apart most likely release the greatest amount of energy.

Answer:
0.16 moles of Carbon
Explanation:
The balanced reaction equation:
+
→
+
↑
The mole ratio of Carbon to Iron is 3 : 4 (since Fe2O3 is in excess)
i.e 3 moles of C produces 4 moles of Fe.
If 1 mole of Fe - 55.8g of Fe
? moles - 11.6g of Fe
= = 0.208 moles
But 3 moles of C - 4 moles of Fe
? moles of C - 0.208 moles of Fe
= = 0.16 moles of carbon.
I hope this explanation was clear and useful.
