<u>Question in English : </u>
<span>
<em>An atom X has 8 neutrons and its atomic number equals 8. Knowing that this atom is isotopes of Y, which has mass number 18, answer: What is the number of neutrons in atom Y?</em>

</span><span><u>Answer :</u>

</span>

Isotopes are defined as the atoms which have same number of protons but different number of neutrons of same element. Since the proton number is same, the atomic number also same. Hence the atomic number of Y is 8.

Mass number = atomic number + neutron number

                   18 = 8 + neutron number

Neutron number = 10

 

Hence, there are 10 neutrons in Y.

GREYUIT [131]

If one of the waste products of cellular respiration is CO2 by means of exhaling, then the rate of cellular respiration increased.

<h3>What is Cellular respiration?</h3>

This consists of series of reactions which combine the chemical energy from foodstuffs and oxygen to form ATP and other waste products such as carbon dioxide and water.

During this process, the carbon dioxide is transported from the mitochondria out of the cell, to the red blood cells, and to the lungs where they are exhaled.

This therefore depicts that the cellular respiration increased as a result of the carbon dioxide given off via exhalation and thereby makes it the correct choice.

2.(04.01 LC)
Mila [183]

Answer:

2KClO3 —> 2KCl + 3O2

The coefficients are 2, 2, 3

Explanation:

From the question given above, we obtained the following equation:

KClO3 —> 2KCl + 3O2

The above equation can be balance as follow:

There are 2 atoms of K on the right side and 1 atom on the left side. It can be balance by putting 2 in front of KClO3 as shown below:

2KClO3 —> 2KCl + 3O2

Now, the equation is balanced.

Thus, the coefficients are 2, 2, 3

For each of the following compounds, identify what type of bonding holds them together.
svet-max [94.6K]

Explanation

NaCl:  Ionic crystal lattice forces

Hg:   Metallic bonding

CO₂:  London dispersion forces

CH₄:  London dispersion forces

Li₂O:  Ionic crystal lattice forces

Ag:  Metallic bonds

Ionic crystal lattice forces are strong electrostatic force of attraction between oppositely charged ions arranged into a crystal lattice of ionic compound. NaCl and Li₂O are ionic compounds

London dispersion forces holds the molecules of carbon dioxide and methane. They are weak attractions found between non-polar (and polar) molecules.

Metallic bonds exists between Mercury and Gold atoms. This is due to sea of electrons present.
