Answer:  Nitrogen is the deadliest gas

Explanation:

It is the most prevalent gas in the atmosphere. Nitrogen comprises more than 75% of the air we breathe. Therefore, N2 is the most lethal of all destructive, dangerous, and toxic gases. Since it is the gas that we breathe in the most, it is found abundantly in the atmosphere.

What is Bacteria?

Bacteria are single-celled microorganisms that exist in their millions, in every environment, both inside and outside other organisms. Bacteria are the most diverse group of organisms on earth, and are believed to be one of the earliest forms of life. They can cause diseases, but can also be beneficial to humans, such as by producing food and vitamins, breaking down organic matter, and helping the body digest food.

Bacteria grows in juice because juice typically contains organic matter and moisture, which provide nutrients and an environment in which bacteria can thrive. Additionally, some types of juice may contain natural sugars and other ingredients which can further encourage bacterial growth.

What is vapor pressure?

Vapor pressure , or equilibrium vapor pressure, is the pressure produced by a vapor in thermodynamic equilibrium with a condensed phase (solid or liquid) at a given temperature. Defined as applied pressure. temperature in a closed system. Equilibrium vapor pressure is a measure of the evaporation rate of a liquid. This refers to the tendency of particles to escape from liquids (or solids). Substances that have a high vapor pressure at room temperature are often called volatile. The pressure that vapor exerts on the liquid surface is known as vapor pressure. As the temperature of a liquid increases, so does the kinetic energy of its molecules. As the kinetic energy of the molecules increases, the number of molecules that become vapor also increases, increasing the vapor pressure.

Molarity of an aqueous solution is  15ˣ10⁻⁷M. if the concentration of an aqueous solution 15ppb.

Molar concentration or Molarity is characterized as the quantity of moles of solute present in an unmistakable measure of liters of the arrangement, that is to say, moles per liters of an answer.

The term Molality was first found in a distribution that goes by the name "Thermodynamics and the Free Energies of Compound Substances", which was distributed in the year 1923 by G N Lewis and M Randall. It is represented by 'm'.

Molarity is the computation of the quantity of solutes that are available in a liter of an answer. As we have referenced before, an answer contains both the solute and the dissolvable. Though, Molality is the estimation of the quantity of solutes that are available in a kilogram of the dissolvable itself. As we definitely know, a dissolvable is something that breaks down the solute.

Now, we are given concentration of aqueous solution is 15ppb,which means in 1 billion number of moles of lead ions are 15

∵In 1 billion ml number of moles of lead ions are =15

∴In 1000 ml number of moles of lead ions are =(15×1000) / 10¹⁰

=>In 1000 ml number of moles of lead ions are=15ˣ10⁻⁷

Hence, molarity of aqueous solution is 15ˣ10⁻⁷M.

We know that the partial pressure is the pressure of a gas that is part of a mixture of gases. Following the law of the partial pressures, it is clear that the number of gases that can be mixed would give rise to the combination of gases that we can call a mixture of gasses.

The total pressure of the mixture of gases can be obtained by the use of the formula that was deduced from the Dalton's law of partial pressures.

Vapor pressure of water in torr = 23.76 torr

Partial pressure of the hydrogen = 742 torr - 23.76 torr

number of electron - shape

6 - Trigonal

8 - Tetrahedral

10 - Trigonal bipyramidal (TBP)

12 - Octahedral

a. [tex]PF^{+}_4[/tex]

Here, the total valence electrons = 5 + 4 - 1 = 8.

valence electrons of P = 5

Valence electrons of F = 1.

hence, we get the total  F = 4.

So, the number of valence electrons is 8. So the shape is Tetrahedral.

b. [tex]BCl_{3}[/tex]

Here, the total valence electrons = 3 + 3 = 6.

this means that the shape is trigonal planar.

So, the predicted Cl - B - Cl bond angle forming  [tex]BCl_{3}[/tex]  is 120°.

c. [tex]SF_{4}[/tex]

Here, the total valence electrons = 6 + 4 = 10.

valence electrons of P = 6

Valence electrons of 4 F = 4.

So, the number of valence electrons is 10. So the shape is Trigonal Bipyramidal (TBP).

- Go back to step one and repeat with a different element. In complicated cases, you might need to do an element twice or even more often.

- When you are sure everything is balanced, look at the equation again and try to find a greatest common divisor among all multipliers.
