Which of the following requires an oxidizing agent?

1 answer:

3 0

Correct Answer: First Option

An oxidizing agent causes the oxidation of the other atom/element by itself being reduced. In simple words we can state that oxidizing agent gains electrons from the other atom/element i.e. the other atom loses electrons.

From the given options we have to find in which of them electrons are being removed. When the electrons are removed, the number of protons in the atom will be more than the number of electrons. As a result the net charge on the atom will be positive.

First option lists such a change. Initially charge on Al is neutral, 3 electrons are removed and it get +3 charge. This shows that Al is being oxidized, so it needs an oxidizing agent.

Andrews [41]

Answer:

The protein is an organic compound which is made up of the amino acids methionine, arginine, and leucine etc.

Explanation:

Most of the amino acid are linked with others amino acid through peptide linkage to form proteins. The peptide bond is formed between the two amino acid involving carboxylic and amino group.

The proteins produce by this way may be simple, conjugated and derived proteins.

An atomic caution with the charge of +1 has the following electron configuration:1s22s22p63s23p6What is the chemical symbol for

SSSSS [86.1K]

The atomic cation with +1 charge with the following configuration:

1s22s22p63s23p6

Is Potassium (K+), remember potassium have 19 electrons in its neutral state, when if losses one electrons it becomes + with one less electron, meaning it will have 18 electrons as a cation.

There are 2 electrons in 1s orbital as it can be seen from the electron configuration.
