<u>Answer:</u> The mass of manganese(III) oxide produced is 113.03 g
<u>Explanation:</u>
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
......(1)
Given mass of zinc = 46.8 g
Molar mass of zinc = 65.38 g/mol
Plugging values in equation 1:
The given chemical equation follows:
By the stoichiometry of the reaction:
If 1 mole of zinc produces 1 mole of manganese(III) oxide
So, 0.716 moles of zinc will produce = of manganese(III) oxide
Molar mass of manganese(III) oxide = 157.87 g/mol
Plugging values in equation 1:
Hence, the mass of manganese(III) oxide produced is 113.03 g
Answer:
Option (A) Each Zn atom loses 2 electrons, and each Co2+ ion gains 2
Explanation:
To know the right answer to the question, let us observe the changes in the oxidation number of Zn and Co. This is illustrated below:
Zn(s) + Co2+(aq) → Zn2+(aq) + Co(s)
The oxidation number of Zn changes from 0 to +2 indicating that Zn has lose 2 electrons.
The oxidation number of Co changes from +2 to 0 indicating that Co has gain 2 electrons.
Therefore, option A is the correct answer.
The best example I
can give that is observable but does not contain matter is:
sunlight or simply light
Light does not contain matter because it is a beam of energy
or to be specific made up of packet of photons.
