PF₆⁻ does not obey the octet rule due to the electron deficiency is present in PF₆⁻.

In the PF₆⁻  molecule P not follows the octet here, it expands its valency and violates the octet. From the octet calculation, it requires 56 electrons but the valence electrons are 48, so the remaining 8 electrons are accumulated by 8/2 = 4 bonds, but here P makes six bonds which is a violation of octet.

To find formal charges in a Lewis structure, for each atom, you should count how many electrons it "owns". Count all of its lone pair electrons, and half of its bonding electrons. The difference between the atom's number of valence electrons and the number it owns is the formal charge.

The key here is to remember that 1 mole of magnesium hydroxide requires 2 moles of hydrochloric acid to neutralise it.

Mg (OH)2 (s) + 2 HCl (aq) MgCl2 (aq) + 2 H2O (l)

You can state that your sample has 0.10 moles of hydrochloric acid because you are aware that 1 L = 103 mL of the hydrochloric acid solution contains 0.10 moles of hydrochloric acid.

25 mL, 0.10 moles HCl/10 mL = 0.0025 moles HCl

This implies that a full neutralisation will call for

1 mole Mg = 0.0025 moles HCl (OH)

Mg(OH)2 = 0.00125 moles per 2moles of HCl.

Carbon dioxide (CO2) concentrations have increased from 280 to about 380 parts per million during the past 150 years (ppm). the reality that human activity is mostly to blame for this.

what is carbon dioxide?

One carbon atom is covalently doubly linked to two oxygen atoms to produce the chemical substance known as carbon dioxide, with the formula CO2. When the temperature is ambient, it exists as a gas. Although it is invisible to visible light when present in the air, carbon dioxide acts as a greenhouse gas by absorbing infrared radiation.

Looking at historical records of human activity reveals that human activity is the cause of the elevated CO2 levels. Since the industrial revolution, we have used fossil fuels and cleared and burned forest area at a rate that has never been seen before, which turns organic carbon into CO2. A careful analysis of the amount of fossil fuel that has been taken and burned, as well as the amount of land cleared, reveals that we have produced significantly more CO2 than is currently found in the atmosphere.

Our estimated 500 billion metric tons of carbon emissions are sufficient to have increased the atmospheric CO2 concentration to just around 500 parts per million.

Since part of the CO2, we produce can be absorbed by the ocean and terrestrial biosphere, the concentrations have not yet reached that level. The apparent increase is, however, explained by the fact that we produce CO2 more quickly than the ocean and biosphere can absorb it.

The ratio of gas effusion is 2.697.

Effusion: When a gas is contained in a container at a pressure higher than that of the surrounding atmosphere, the gas will escape through a small hole that is opened in the container until the pressures inside and outside are equal. Effusion is the name given to this process.

The rates of diffusion of various gases are inversely correlated to the square roots of their molecular masses or densities, according to Graham's law of diffusion, which states "under the same conditions of temperature and pressure."

The number of molecules that diffuse through the hole in one unit of time is the rate of effusion. The effusion rate is inversely related to the molecular weight when pressure and temperature are constant.

Inversely related to √M is the effusion rate.

The empirical formula for the hydrocarbon is CH2.

What is empirical formula?

An empirical formula is a simple way of expressing the relative numbers of atoms of each element in a compound. It is expressed as the ratio of the number of atoms of each element in the compound, with the smallest whole-number ratio being written as the empirical formula. This formula does not give any information about the actual concentration of atoms or molecules in the compound, nor does it indicate the exact structure of the compound. For example, the empirical formula for glucose is CH₂O, which indicates that for every one atom of Carbon (C), there are two atoms of Hydrogen (H), and one atom of Oxygen (O).

Here we use number of moles of water and carbon dioxide to determine how many moles of carbon and hydrogen are present.

so, for water 5.41 g. 1 mole of h2o/ 18.05g= 0.300g moles

The temperature of the gas will be 800k.

The initial temperature of the ideal gas in the tank is: T1 =400 K

The initial pressure of ideal gas in the tank is: P1 = 1 atm

The final pressure of the ideal gas is: P2 = 2 atm

To get the temperature T2, we must apply the equation and concepts from the ideal gas law.

It may be described mathematically as :

PV = nRT

where,

P = Pressure

V = Volume

n = Number of moles

R = Gas constant

T = Temperature

When the number of moles and volume remains constant, the expression can be written as:

P1/T1 = P2/T2

T2 = (P2×T1) / P1

On putting the given values, we get:

T2 = 2 × 400 / 1

T2 = 800 / 1

T2 = 800K
