Explanation:

Answer:

0.36 moles

Explanation:

Given data:

Number of moles of SO₃ form = ?

Number of moles of SO₂ react = 0.36 mol

Solution:

Chemical equation:

2SO₂ + O₂      →      2SO₃

Now we will compare the moles of SO₃ with SO₂.

                       SO₂           :           SO₃

                         2             :            2

                       0.36         :           0.36

Thus, from 0.36 moles of SO₂ 0.36 moles of SO₃ formed.

Answer:

The answer is B.  A river is a body of water, therefore, there will always be some water running over the rock.

Answer:

The answer is: B

Explanation:

The reason for this is because when a rock is underwater (the river, in this case), the water runs across it non-stop until the rock is removed from the water. The only way it can be polished if it is submerged under the water for quite some time (years and years).

Effusion refers to the movement of a gas through a small hole. It is different from diffusion which involves the movement of a gas from a region of higher concentration to a region of lower concentration.

The effusion of a gas is described by Graham's law. According to Graham's law, the rate of effusion of a gas is inversely proportional to the square root of the molar mass of the gas.

The following are true regarding the effusion of a gas;

by eating healthy food and having a balanced diet also by exercising

An athlete might be able to increase their cellular respiration through the consumption of a balanced diet along with a regular exercising pattern.

Cellular respiration may be defined as a process through which organisms break down the molecules of glucose within the cell in order to avail energy in form of ATP for metabolic and cellular processes.

As we all know that glucose molecules and oxygen are the reactants for cellular respiration. So, a better level of glucose can be availed by a healthy and balanced diet and a standard oxygen level can be availed through a regular exercising pattern.

Therefore, an athlete might be able to increase their cellular respiration through the consumption of a balanced diet along with a regular exercising pattern.

Mass of sample of silver = 53.93 g

Number of atoms of silver = ?

Solution:

Number of moles of silver:

Number of moles = mass/ molar mass

Number of moles = 53.93 g/ 107.86 g/mol

Number of moles = 0.5 mol

Number of atoms of silver:

Ionic Bonding (the transfer of valence electrons)

Answer:

Ok:

Explanation:

Sodium gives fluorine an electron. This is in part due to electronegativity differences because sodium likes to lose an electron and fluorine likes to gain. As a result, sodium and become positively charged and fluorine negatively charged. This will for electrostatic attraction and the sodium and fluorine will form a bond. This bond is called an ionic bond.

Answer:

C . 24 L

Explanation:

Given data:

Initial volume of gas = 20.0 L

Initial pressure of gas = 660 mmHg

Final volume = ?

Final pressure = 550 mmHg

Solution:

The given problem will be solved through the Boly's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

Now we will put the values in formula,

P₁V₁ = P₂V₂

660 mmHg × 20.0 L = 550 mmHg × V₂

V₂ = 13200 mmHg. L/ 550 mmHg

V₂ = 24 L

Answer:

B) 12

Explanation:

Given parameters:

Initial volume  = 3L

Initial pressure  = 4atm

Final pressure  = 6atm

Unknown:

Final volume  = ?

Solution:

To solve this problem, we apply Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".

   P₁V₁  = P₂V₂

 P and V are pressure and temperature values

 1 and 2 are initial and final states.

    PV product  = 3 x 4 = 12

The [tex]P \times V[/tex] product of this given sample of gas is equal to: B) 12 atm.

Given the following data:

To determine the [tex]P \times V[/tex] product of this given sample of gas, we would apply Boyle's law:

Boyle's law states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyle's law is given by the formula;

[tex]PV = k\\\\P_1V_1 = P_2V_2[/tex]

Where;

Substituting the given parameters into the formula, we have;

[tex]P \times V = 4 \times 3\\\\P \times V = 12\;atm[/tex]
