The Fluoride ion given has a -ve charge onto it. Thus in order to become stable Fluorine gains an electron. Thus option b is correct.

The elements in the periodic table try to attain the stable noble gas configuration in the order to become stable. The noble gas configuration has the elements to be less reactive.

When the atom loses an electron in order to become more stable,  a +ve charge has been implemented onto the ion.

When the atom gains an electron to become stable, a -ve charge has been added to the ion.

The Fluoride ion given has a -ve charge onto it. Thus in order to become stable Fluorine gains an electron. Thus option b is correct.

Answer:

The volume of a gas is determined by the volume of the container it is in. Gases take the shape of their container and the volume of the container....

Explanation:

What happens to the volume or size of a balloon as it rises in the air?

When a balloon goes up higher in the air, its size will increase. Since there's less air in the upper atmosphere, there's less stuff pushing back on the balloon, and hence the pressure is lower, which allows the balloon to expand.

Is pressure inside a balloon greater?

The pressure inside the balloon is higher than the pressure on the outside. ... And the direction of airflow is always from higher to lower pressure. If the pressure was same then there would be no airflow and if the pressure outside was higher , air will flow from outside to the inside of the balloon.

What is the relationship between volume and pressure?

Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice versa, when temperature is held constant. Therefore, when the volume is halved, the pressure is doubled; and if the volume is doubled, the pressure is halved.

Two design criteria for the design of the ammonia making process are;

1) Sustainable hydrogen production by renewable energy

2)  Sustainable use of the ammonia-water thermal absorption cycle to retrieve the ammonia present in the waster water

Explanation:

Ammonia is produced from natural gas in the following process;

H₂ + RSH → RH + H₂S

H₂S + ZnO → ZnS + H₂O (Waste water)

CH₄ + H₂O → CO + 3H₂

CO + H₂O → CO₂ + H₂

Ammonia is then produced by reacting the produced hydrogen with nitrogen in the presence of a catalyst in a process known as the Haber-Bosch process as follows;

3H₂ + N₂ → 2NH₃

The

The design criteria for the design of the ammonia making process therefore as follows;

1) Sustainable use of renewable energy to produce hydrogen gas from the electrolysis of water

2)  Use of the ammonia-water thermal absorption cycle to retrieve the ammonia present in the waster water.

Answer:

the answer is A

Explanation:

Forces are the intermolecular interaction between the matter. Forces present in a solid are strongest. Thus, option A is correct.

The matter is any substance that occupies a volume. Matter can be a solid, gas, or liquid. The solid phase particles are tightly closed to each other making the force strong.

The particles of liquids that are not too compact are a little free and in gases, the particles are very free, which makes the bonding and the force the weakest.

Therefore, option A. the solids have the strongest intermolecular bonding.

C. A linear, nonpolar molecule

Explanation:

Molecules which are alike usually have the same degree of pull which results in them sharing electrons. This sharing of electrons is known as the molecules exhibiting Covalent bonding between them.

The equal pull also results in the cancelling out of electrons and favoring non polar bonds due to the absence of free electrons which would have been able to interact with H2O in a polar binding system.

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

To calculate the moles, we use the equation:

1. [tex]\text{Number of moles of sulpfuric acid}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{3.2g}{98g/mol}=0.033moles[/tex]

1 mole of [tex]H_2SO_4[/tex] contains = [tex]6.023\times 10^{23}[/tex] molecules of sulfuric acid

Thus mole of [tex]H_2SO_4[/tex] contains = [tex]\frac{6.023\times 10^{23}}{1}\times 0.033=0.20\times 10^{23}[/tex] molecules of sulfuric acid

There are [tex]0.20\times 10^{23}[/tex] molecules of sulfuric acid  in the solution.

Answer:

The total energy to break all the bonds in 1 mole of 1-propanol, C₃H₈O, is 4411 kJ/mol

Explanation:

We note that propanol, C₃H₈O is also known as 1-propanol is written as follows;

CH₃CH₂CH₂OH which gives

CH₃-CH₂-CH₂-OH

Hence, the total number of bonds are;

C-H Bonds = 3 + 2 + 2 = 7

C-O Bonds = 1

O-H Bond = 1

C-C Bonds = 2

The bond energies are as follows;

C-H Bonds = 413 kJ/mol

C-O Bonds = 358 kJ/mol

O-H Bond = 468 kJ/mol

C-C Bonds = 347 kJ/mol

Energy required to break the bonds in 1-propanol is therefore;

C-H Bonds = 413 kJ/mol × 7 = 2,891 kJ/mol

C-O Bonds = 358 kJ/mol × 1 = 358 kJ/mol

O-H Bond = 468 kJ/mol × 1 = 468 kJ/mol

C-C Bonds = 347 kJ/mol × 2 = 694 kJ/mol

The total energy to break all the bonds in 1 mole of 1-propanol = 4411 kJ/mol.
