Answer:

The combination of oxygen with other substances to produce new chemical products is called Oxidation.

Explanation:

Oxidation reactions are defined as,

In terms of Inorganic chemistry:

(i) Removal of Electrons:

Example: Mg → Mg²⁺ + 2 e⁻

(ii) Addition of Oxygen:

Example: 2 Mg + O₂ → 2 MgO

In terms of Organic chemistry:

(i) Addition of Electrons:

Example: Cl₂ + 2 e⁻ → 2 Cl⁻

(ii) Addition of Hydrogen:

Example: H₂CCH₂ + H₂ → H₃CCH₃

It is important to understand that while the absorbance value is related to the amount of light absorbed by a sample, it is not

Trava [24]

When 100 photons of light pass through a sample and 64 photons are detected after the passage of light, the number of photons transmitted through the sample is 64.

This is based on the methods of calculating the absorbance of light, which is depicted as the higher the amount of light transmission, the lower the amount of light absorbed.

Thus, when 64 photons of light in 100 photons are detected, 64 photons are transmitted, and therefore, the number of photons absorbed is 36.

Hence, hypothetically, if 100 photons of light are transmitted, 0 photons of light will be absorbed.

Therefore, in this case, it is concluded that the correct answer is 64 photos.

Answer:

The correct answer is B. exogenous

Explanation:

Let us try to describe exogenous and endogenous variables an exogenous variable value is influenced only by factors outside a model or system and is forced onto the model, while a change in an exogenous variable is known as an exogenous change. Also an endogenous variable is one whose value is influenced only by the system or model under study.

Answer:

The correct answer is B) electronegativities of the bonded atoms in a molecule of the compound .

Explanation:

When two atoms forming a bond differ in their electronegativities at that time bond polarity is generated

In simple words a bond will be polar when the bonding electrons are not equally shared by two atoms.As a result the atom attract the bonding electron pair towards itself gain partial negative charge and the other atom gains partial positive charge.

For HCl is a polar compound because H and Cl atom differ in their electronegativities,as a result the bonding electron pair is not shared equally by H and Cl atoms.
