According to Avogadro's law equal volume of all gases at the same temperature and pressure contain equal number of molecules. At STP one mole of any gas behaving ideally occupies a volume of 22.414 L.

What is molar volume?

The volume occupied by one mole of a substance at a given temperature and pressure is defined as the molar volume at that temperature and pressure. The value of molar volume of an ideal gas at STP is important in stoichiometric calculations.

At STP, the number of molecules of a gas is given as:

Number of molecules of a gas (N) = V₀ in L /  22.414 × 6.022 × 10²³

Here  V₀ in L = 16500 = 16.5 L

N =  16.5 / 22.414  × 6.022 × 10²³

N = 4.433 × 10²³

Thus the number of molecules present is 4.432 × 10²³.

An atom that has 84 protons and 86 neutrons undergoes a reaction. At the end of the reaction, it has 82 protons and 84 neutrons. What happened to the atom? It accepted radiation in a chemical reaction. It donated neutrons to another atom in a chemical reaction. It emitted an alpha particle in a nuclear reaction. It released a beta particle in a nuclear reaction.

Answers

Answer:

C

Explanation:

It denotes a loss of 2 protons and 2 neutrons for the atom. As a result, the atom released an alpha particle, which is composed of two protons and two neutrons, hence option C is correct.

What is an alpha particle?

The structure of alpha particles, also known as alpha rays or alpha radiation, is similar to that of the helium-4 nucleus and is made up of two protons and two neutrons bonded together.

They often result from the alpha decay process, although they can also result from other processes.

If an atom has 84 protons and 86 neutrons, after the reaction, the atom has 82 protons and 84 neutrons, it suggests that the atom has lost 2 protons and 2 neutrons.

Therefore, the atom emitted an alpha particle in a nuclear reaction, hence option C is correct.

In order to make a covalent bond, the orbitals on each atom in the bond must overlap.

Answers

Answer:

true

Explanation:

Covalent bonds are formed through the overlap of half-filled valence orbitals. Because of the overlapping, it is most probable that electrons are located within the region of the bond.

In order to make a covalent bond, the orbitals on each atom in the bond must overlap. Therefore, the given statement is true.

What is covalent bond?

A covalent bond is an electron exchange usually results in the production of electron pairs between atoms. These electron couples are referred to as bonding pairs as well as sharing pairs. Covalent bonding seems to be the permanent equilibrium of atoms' forces of attraction versus attraction when atoms share electrons.

Because to electron sharing, each atom in a number of molecules can achieve the corresponding amount of the valence shell, resulting inside a stable electronic configuration. In organic chemistry, covalent bonds are far more common than ionic ones. In order to make a covalent bond, the orbitals on each atom in the bond must overlap.

What is the temperature change if 400 J of energy is added to 10 grams of water

A) 40 degrees Celsius
B) 1 degrees Celsius
C) 100 degrees Celsius
D) 10 degrees Celsius

Answers

The temperature change if 400 J of energy is added to 10 grams of water is 9.57°C.

How to calculate temperature change?

The temperature change of a calorimeter can be calculated using the following expression:

E = mc∆T

Where;

E = energy in joulesm = massc = specific heat capacity = 4.18J/g°C∆T = change in temperature

400 = 10 × 4.18 × ∆T

400 = 41.8∆T

∆T = 400/41.8

∆T = 9.57°C

Therefore, the temperature change if 400 J of energy is added to 10 grams of water is 9.57°C.

What is the molarity of a solution that has 26 moles of nacl in 2. 7 l of water?.

Answers

The molarity of a solution that has 26 moles of NaCl in 2.7L of water is 9.63M.

How to calculate molarity?

The molarity of a solution can be calculated by dividing the number of moles of the solute by the volume of the solution as follows:

Molarity = no of moles ÷ volume

According to this question, a solution has 26 moles of NaCl in 2. 7 l of water. The molarity is as follows:

Molarity = 26mol ÷ 2.7L

Molarity = 9.6M.

A chemist dilutes a 1.0 ml sample of 2.0 m kno3 by adding water to it. if the concentration of the solution that is obtained is 0.0080 m, what is its volume? use m subscript i v subscript i equals m subscript f v subscript f.. 125 ml 250 ml 500 ml 2,000 ml

Answers

A chemist dilutes a 1.0 ml sample of 2.0M KNO₃ by adding water to it. If the concentration of the solution that is obtained is 0.0080 m, then its volume is 250mL.

How do we calculate volume?

Volume for the given equation will be calculated by using the below equation as:

M₁V₁ = M₂V₂, where

M₁ = molarity of KNO₃ = 2M

V₁ = volume of KNO₃ = 1mL

M₂ = molarity of final solution = 0.0080M

V₂ = volume of final solution = ?

On putting these values on the above equation, we get

V₂ = (2)(1) / (0.0080) = 250mL

For an impure sample of potassium hydrogen phthalate, the percentage of potassium hydrogen phthalate is

m'=39.3%

What is the percentage of potassium hydrogen phthalate if 2.81 g of the mixture required 35.61 mL of 0.152 mol/L NaOH to reach the end point?

Generally, the equation for the mol base  is mathematically given as

mol base = M*V

mol base = 0.152*35.61

mol base = 5.41272 mmol

In conclusion

mass = mmol/1000*MW

m== 5.41272 /1000*204.22

m= 1.1053 g of KHP
