A reaction in which bonds are created is usually associated with the Release of energy.

What are the various types of bonds?

There are three sorts of bonds:

1. Electrovalent or electrovalent bond

2. chemical bond

3. dative bond

Electrovalent or electrovalent bond are formed when one or more electrons are transferred from one atom to another.

Covalent bonds are formed when the atoms during a molecule share an equal number of electrons.

A dative bond is one in which both electrons in a shared pair come from the same atom.

Now, atoms tend to stabilize once they form chemical bonds, releasing energy within the process. Energy is released because there's a higher level of stability associated with a low energy level.

Hence, a reaction in which bonds are created is usually associated with the release of energy.

RUDIKE [14]

Answer:

76 mmHg is the partial pressure of oxygen on this new planet.

Explanation:

Atmospheric pressure on air on earth = 760 mmHg

On an unknown planet :

Oxygen makes up 10% of the atmosphere.

The mole fraction of oxygen gas can be written as = $\chi_1=\frac{10}{100}=0.1$

Carbon dioxide makes up 15% of the atmosphere.

The mole fraction of carbon dioxide gas can be written as = $\chi_2=\frac{15}{100}=0.15$

Nitrogen makes up the remaining 75% of the atmosphere.

The mole fraction of nitrogen gas can be written as = $\chi_1=\frac{75}{100}=0.75$

Atmospheric pressure of air on unknown planet,p= 760 mmHg (given)

Partial pressure of gases can be calculated by the help o Dalton's law of partial pressure:

Partial pressure of oxygen gas :

$p_1=p\times \chi_1$

$p_1=760 mmHg\times 0.1=76 mmHg$

Partial pressure of carbon dioxide gas :

$p_2=p\times \chi_2$

$p_2=760 mmHg\times 0.15=114 mmHg$

Partial pressure of nitrogen gas :

$p_3=p\times \chi_3$

$p_3=760 mmHg\times 0.75=570 mmHg$

Georgia [21]

D) the college students

Explanation:

In the experiment conducted by staffs of the nursing home, the group of college students that came for the experiment are the subjects of the experiment. A subject is a person that participates in a research.

In this research, the college students are the human participants in the experiment.
There must be a mutual agreement between the researcher and the subject because the subject is one that is being tested to see an outcome.
A subject can quit a research if he/she deems it fit at any time.

Which statement is true about AC?

AysviL [449]

According to the research, the correct option is A. The electrons move back and forth is the statement that is true about AC.

It is the flow of electric charges through a conductor is called electric current, if said flow of electric current varies in direction from time to time, we speak of alternating current.

Subatomic particles such as protons and electrons have an electrical charge, a physical property that is manifested by the repulsive and attractive forces that exist between them in AC the electrical charge moves back and forth.

Therefore, we can conclude that according to the research, the correct option is A. The electrons move back and forth is the statement that is true about AC.
