Answer:

628.520 mmHg

Explanation:

1 atm = 760 mmHg

[tex](760 \div 1) \times 0.827[/tex]

The pressure of 0.827 atm in mmHg is 628.52 mmHg

Pressure has various units of measurement such as atmosphere (atm), pascal, mmHg, Newton per square metre (N/m²) etc. These units can be converted from one to the other.

Considering the question given above, we can convert 0.827 atm to mmHg as illustrated below:

1 atm = 760 mmHg

Therefore,

0.827 atm = 0.827 × 760

0.827 atm = 628.52 mmHg

Thus, 0.827 atm is equivalent to 628.52 mmHg

Windstorm Hope it helped brainiest plz and thank you have a great day!!!

Explanation:

Which of the following natural processes will NOT directly result in the formation of sedimentary rock?

B. Windstorm

A. The mass (in grams) of Ce(NO₃)₄ that will be required to make the solution is 24.16 g

B. The concentration of the nitrate ions in the solution is 1.66 M

C. The new concentration of the Ce(NO₃)₄ solution is 0.178 M

We'll begin by calculating the number of mole of Ce(NO₃)₄ in the solution.

Molarity = 0.415 M

Volume = 150 mL = 150 /1000 = 0.15 L

Mole = Molarity × Volume

Mole of Ce(NO₃)₄ = 0.415 × 0.15

A. Determination of the mass of Ce(NO₃)₄ required to make the solution.

Mole of Ce(NO₃)₄ = 0.06225 mole

Molar of Ce(NO₃)₄ = 140.12 + 4[14 + (16×3)]

= 140.12 + 4[14 + 48]

= 140.12 + 4[62]

= 140.12 + 248

= 388.12 g/mol

Mass = mole × molar mass

Mass of Ce(NO₃)₄ = 0.06225 × 388.12

Therefore, 24.16 g of Ce(NO₃)₄ is required to make the solution.

B. Determination of the concentration of the nitrate ion, NO₃¯ in the solution.

In solution, Ce(NO₃)₄ will dissociate as follow:

Ce(NO₃)₄ (aq) —> Ce⁴⁺(aq) + 4NO₃¯(aq)

From the balanced equation above,

1 mole of Ce(NO₃)₄ contains 4 moles of NO₃¯

Therefore,

0.415 M solution of Ce(NO₃)₄ will contain = 0.415 × 4 = 1.66 M NO₃¯

Thus, 1.66 M of the nitrate ion, NO₃¯, is present in the solution.

C. Determination of the new concentration of the Ce(NO₃)₄ solution.

Volume of stock solution (V₁) = 150 mL

Molarity of stock solution (M₁) = 0.415 M

Volume of diluted solution (V₂) = 350 mL

Molarity of diluted solution (M₂) =?

0.415 × 150 = M₂ × 350

62.25 = M₂ × 350

Divide both side by 350

M₂ = 62.25 / 350

Therefore, the new concentration of the Ce(NO₃)₄ solution is 0.178 M

Answer:

because theres a force called gravity

Explanation:

Under conditions of very high pressures, the volume would be lower than predicted by the Ideal Gas Law.

According to the kinetic theory of gases, a gas spreads out to fill the volume of the container holding it. Hence a gas does not have a definite volume due to the fact that there is no inter-molecular interaction between gas molecules.

When the gas is subjected to very high pressure, inter-molecular interactions become significant leading to a decrease in the volume of the gas.

Therefore, when subjected to high pressure, the experimental volume would be lower than predicted by the Ideal Gas Law.

The density of the rectangular block is 1.07 g/mL.

From the question, we have the mass of the rectangular block as 121g

The dimensions of the block are given as follows;9.1cm by 5.4cm by 2.3cm

So we have the volume of the block as; 9.1cm × 5.4cm ×  2.3cm = 113 cm^3

Let us recall that; 1 cm^3 = 1 mL, so 113 cm^3 = 113 mL

Having said that, we must also remember that;

Density = Mass/volume

Density = 121g/113 mL

Density = 1.07 g/mL

Answer:

1) Convert percent (m/V) to molarity

percent (m/V)=1.15 grams/100ml=1.15 g/0.1L=11.5g/L

molarity of KBr=mol/L=g/L *(1mol/molecular weight of KBr)=(11.5g/L) * (1mol/119.0g/mol)=0.0966 mol/L=0.0966M

2) calculation of osmol from mol

In solution, KBr dissociates into two ions K+ and Br- so there are 2 osmol of KBr per mol

3) calculation of osmolarity=molarity*2=0.0966*2=0.193 Osm or Osmolar

Answer:

C. A Spring Scale

Explanation:

Using process of elimination, we can quickly decide that a stopwatch and a ruler will not be useful in measuring the force. This leaves us with either the spring scale or a balance scale. A balance scale is used to compare two weights, so this is eliminated. That leaves us with a spring scale. This is because we can attached the spring scale to the car and when we let it go, we can record the force. I hope this helps!

Answer:

This isotope has 59 electrons giving it a charge of -2.

Explanation:

To find this we have to understand isotope relates to the mass of the nucleus. This isotope has 59 electrons to counter the protons and give it a negative charge.

In an atom, the atomic number is equal to number of electrons , hence element Q has 57 electrons on addition 2 electrons that is -2 charge the number of electrons is 59 electrons.

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

Explanation:

The mass percent of benzoic acid in the sample is 55.5%.

The equation of the reaction is; HC7H5O2(aq) + NaOH(aq) ----> NaC7H5O2(aq) + H2O(l)

Number of moles of NaOH reacted = concentration × volume

Number of moles of NaOH reacted = 10.59/1000 L × 0.1546 M

Number of moles of NaOH reacted = 0.0016 moles of NaOH

Since the reaction is 1:1, 0.0016 moles of HC7H5O2 reacted also.

Hence, mass of HC7H5O2 = 0.0016 moles × 122 g/mol = 0.1952 g

Mass percent of HC7H5O2 in the original sample = 0.1952 g/ 0.3518 g × 100 = 55.5%
