Answer: only Br2.
Justification.
In a chemical reaction the element that gains electrons experiments a reduction in its oxidation state, that is why it is said that it is reduced.
So, to know what element is being reduced you need to calculate the oxidation states of the elements involved.
Here I indicate the oxidation states of each element if the reaction putting them inside parenthesis:
Reactants side Products side
K (0) K (1+)
Br (0) Br(1-)
So, K lost one electron, increasing its oxidation statefrom 0 to 1+, meaning that it is being oxidized.
And, each atom of Br gained one electron, reducing its oxidation state from 0 to 1-, meaning it is being reduced.
Therefore, the answer is that Br2 is the substance being reduced.
a wave that the medium is displaced perpendicular to the direction of the wave, such as waves on a string.
Explanation:
A transverse wave is a wave that the medium is displaced perpendicular to the direction of the wave, such as waves on a string.
A wave is a disturbance that transmits energy from one place to another.
There are two major types of waves:
- Transverse waves are waves that are propagated perpendicularly to the direction of the wave.
- A wave in string going up and down is a transverse wave.
- Electromagnetic waves are transverse waves.
- Seismic s-waves are transverse waves.
- Sound waves are longitudinal waves propagated parallel to their source.
