Which element is reduced in the reaction below? a. na b. ci c. ba d. none

The correct answer is Option D.

Explanation:

For the given chemical reaction:

The above chemical reaction is considered as double displacement reaction because here exchange of ions takes place.

In these type of reactions, oxidation state of the atoms remains the same.

On the reactant side:

Oxidation state of barium = +2

Oxidation state of chlorine = -1

Oxidation state of sodium = +1

On the product side:

Oxidation state of barium = +2

Oxidation state of chlorine = -1

Oxidation state of sodium = +1

Thus, the correct answer is Option D.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

did anyone actually do this? like if anyone has submitted this i rly need .
