Answer:
The correct answer is 2.33g of 
, A
Explanation:
We can use basic stoich to get this question.
To start, lets convert our grams to moles in order to use our equation. 5.38g of 
moles.
We then can use our molar ratio of 13:10. Simply divide by our molar ratio in order to go from moles of 
to moles of . This gets us 0.129335 moles of .
Now lets convert to grams of by multiplying by the molar mass of . 
of
C: Lithium. Before it was 4Li and after the oxidation it turned out to 2Li
Equation is as follow,
Fe₂O₃ + 3 CO → 2 Fe + 3 CO₂
Oxidation:
3 CO → 3 CO₂
Oxidation state of C in CO is +2, and that in CO₂ is +4. So, carbon has lost 2 electrons per mole and 6 electrons per 3 moles hence,
3 CO → 3 CO₂ + 6 e⁻
Reduction:
Fe₂O₃ → 2 Fe
Oxidation state of Fe in Fe₂O₃ is +3 per atom, and that in Fe is 0. So, Iron has gained 3 electrons per atom and 6 electrons per 2 atoms hence,
Fe₂O₃ + 6e⁻ → 2 Fe
Result:
Iron in Fe₂O₃ has been reduced in this reaction and has played a role of oxidizing agent by oxidizing carbon from +2 state to +4 state.
Answer: 
is the correct equation for beta decay.
Explanation:
When a beta particle, that is, 
is emitted in a radioactive decay then it is known as beta decay.
Therefore, beta decay of Polonium-218 is as follows.
Therefore, we can conclude that is the correct equation for the given beta decay.
