Question 24 of 25
How can one tell if a reaction is a redox reaction?
O A. Elements change phases.
O B. A precipitate is formed.
O C. Spectator ions are present.
O D. Electrons are gained and lost.

Answers

Answer:

D. Electrons are gained and lost

Explanation:

When electrons are gain and lost, redox reaction takes place. In redox reaction, reduction and oxidation tales place simultaneously. Therefore, option D is correct.

What is redox reaction ?

Redox reactions include a change in the oxidation state of the substrate. When electrons are lost or the oxidation state increases, it is called oxidation; when they are gained or the oxidation state decreases, it is called reduction.

Redox reactions are those in which there is a change in the oxidation number, with both an increase and a drop in number. The reaction called non-redox if this does not take place.

Oxidation and reduction always occur jointly because any loss of electrons by one substance must be followed by a gain of electrons by another. Therefore, oxidation-reduction processes or simply redox reactions are other names for electron-transfer events.

Thus, option D is correct.

Select all the statements that correctly describe a solution. Multiple select question.

B. A solution may have more than one solute.
C. Not all solutions are liquid.
D. A solution is a homogeneous mixture of two or more substances.
E. The solute is the substance present in the largest quantity.

Answers

Answer:

B, D, C

Explanation:

the solution may have more than one solute, a solution is a homogenous mixture of 2 or more substances and not all solutions are liquid

A solution is formed by the mixture of substances dissolved in water. There may have more than one solute. Not all solutions are liquid but there exists solid solutions too. Hence, options A, B, C are correct.

What are solutions?

A solution is a combination of a solvent and a solid solute. The solute can be completely dissolved in the solvent and can have a partial solubility.

Water is a good solvent which dissolve majority of compounds. But there are other solvents too forming solution with suitable solutes. Solutions can be homogenous or heterogenous. Homogenous solutions are forming one phase and the solute particles are uniformly arranged.

Heterogeneous solutions are those where the solute particles are arranged in a non-uniformity and they form a different phase from the solvent.

There can be more than one solute in a solution provided that the solute can be of miscibility with each other.
