Answer : The correct option is,
Explanation :
- Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. That means, the loss of electrons takes place.
Or we can say that, oxidation reaction occurs when a reactant losses electrons in the reaction.
- Reduction reaction : It is defined as the reaction in which a substance gains electrons. That means, the gain of electrons takes place.
Or we can say that, reduction reaction occurs when a reactant gains electrons in the reaction.
According to the electrochemical series, most likely to be reduced because
Hence, the ion most likely to be reduced is .
7.5g
Explanation:
Given parameters:
Mass of Fe₂O₃ = 25g
Unknown:
Mass of oxygen that can be removed = ?
Solution:
Find the ratio of the oxygen atoms to that of the compound using the molar mass. Then multiply with the given mass.
Mass of oxygen = }[/tex] x given mass
Mass of oxygen = x 25 = 7.5g
