Which process takes place when recharging a rechargeable battery?

Answers

Answer:

The correct answer is "Oxidation at the anode and reduction at the cathode".

Explanation:

A rechargeable battery is recharged by the movement of electrons from an external power source into the battery. In order to achieve this, two process take place inside the rechargeable battery: oxidation at the anode and reduction at the cathode. The electrons flow within the battery from the anode to the cathode, this happens by the oxidation of the anode (loss of electrons) and the reduction at the cathode (gain of electrons).

Find the mass of 3.00 mol of acetic acid, C2H4O2

Answers

Molar mass acetic acid:

C₂H₄O₂ = 12 * 2 + 1 * 4 + 16 * 2 = 60.

n = mass / molar mass

3.00 = m / 60.0

m = 3.00 * 60.0

m = 180 g of C₂H₄O₂

Which is an example of a beneficial mutation? ANSWERRRR HELPPP !!! choices : one that changes the color of a rabbit, allowing it to hide from predators.

one that results in lighter flower petal colors without changing the plant’s ability to reproduce

one that causes a person’s body to produce thick mucus that clogs the lungs


one that makes it easier for a corn plant to contract a disease

Answers

Mutation can be defined as the change in the genetic sequence that is hereditary. The example of beneficial mutation can be the change of rabbit color to help him hide from the predators.

What are mutagens?

The mutation can be caused by the exposure of the gene sequence to the mutagen that cause the hereditary change.

The mutagens can be UV radiation, high energy, radiation, chemicals, or environmental factors.


The beneficial mutation can be given as the mutation in which the organism has been benefitted. The change in the color pf rabbit benefit him in hiding from the predators. Thus, option A has been the example of the beneficial mutation.
