What is an air mass? Where on Earth might you find a hot and dry air mass?

Answers

Answer 1
An air mass is a large volume of air in the atmosphere thats mostly uniform in temperature and moisture. Air masses can extend thousands of kilometers across the surface of the Earth, and can reach from ground level to the stratosphere/10 miles into the atmosphere. an air mass over northern Canada is a continental polar air mass and is cold and dry. One that forms over the Indian Ocean is called a maritime tropical air mass and is warm and humid.
Answer 2

An air mass is a volume of air whose temperature and humidity are specified. Many hundreds or thousands of square miles are covered by air masses, which adjust to the properties of the land underneath them.

What is an air mass ?

An air mass is a volume of air whose temperature and humidity are specified. Many hundreds or thousands of square miles are covered by air masses, which adjust to the properties of the land underneath them. Latitude and their continental or marine source regions are used to categorize them.

There is a temperature and air pressure differential. Storms are caused by abrupt changes in the weather. Two natural wind patterns come into conflict.

The hot and dry continental tropical (cT) air mass is prevalent over subtropical and tropical continents. The world's largest deserts, such the Sahara, Arabian, and Australian, are important source areas.

Thus, Latitude and their continental or marine source regions are used to categorize them. An air mass is a volume of air whose temperature and humidity are specified.

The number of moles of water decreases.
The molarity of the solution increases.
The molarity of the solution decreases.

Answers

When sugar is added to a glass of sugar solution, the molarity of the solution increases. Details about molarity can be found below, which is the third option.

What is molarity?

Molarity is a term used to identify the amount of solute, in moles, dissolved in a solvent by volume. Molarity is expressed as moles per liter (mol/L).

However, molarity is directly proportional to the amount of solute in solution. This means that as the amount of solute increases, molarity also increases.

Therefore, when sugar is added to a glass of sugar solution, the molarity of the solution increases.

A mixture of reactants and products for the reaction shown below is at equilibrium in a 5.0 L container what would most likely happen to the equilibrium if the volume of the container will reduced to 3.0 L?

Answers

Since the volume decreased, it means that the pressure is going to rise. Thus, the equilibrium of the reaction will shift in the direction that has the least amount of moles.

The statement, that describes the equilibrium "will change in the direction with the minimum moles."

What is an equilibrium?

A condition of equilibrium has become one of balance. Chemical equilibrium is the state in which both the reactants and products are present in concentrations that have no further tendency to change with time, resulting in no observable change in the system's properties.

When volume decreases, the equilibrium shifts to favor the direction that produces fewer moles of gas. When the volume is raised, the equilibrium shifts in favor of the direction that produces the most moles of gas. Because the container's volume will be lowered from 5.0 L to 3.0 L, the pressure will rise. As a result, the equilibrium of the reaction will shift in the direction with the fewest moles. When the volume is reduced, the pressure rises. This demonstrates that a gas's pressure is inversely proportional to its volume.

Hence the correct answer is equilibrium will change in the direction with the minimum moles.

1) 1.0 L

2) 1.5 L

3) 2.0 L

4) 3.0L

Answer:

2.0 L

Option C) 2.0L is the correct answer.

Hence, at the same temperature, as the pressure is increased to the given value, the volume of the gas decreases to 2.0L.

Boyle's law

Boyle's law states that "the volume V of a given quantity of gas is inversely proportional to its pressure P as long as temperature remains constant.

Boyle's law is expressed as;

P₁V₁ = P₂V₂

Given the data in the question;

Initial Volume V₁ = 2.5LInitial pressure P₁ = 6.0atmFinal pressure P₂ = 7.5atmFinal volume V₂ = ?

To determine the final volume of the gas, we substitute our given values into the expression above.

P₁V₁ = P₂V₂

V₂ = P₁V₁ /  P₂

V₂ = ( 6.0atm × 2.5L ) /  7.5atm

V₂ = 15Latm / 7.5atm

V₂ = 2.0L

Option C) 2.0L is the correct answer.

Hence, at the same temperature, as the pressure is increased to the given value, the volume of the gas decreases to 2.0L.

Calculate the molar mass of the following compound: Ca3P2

Answers

Answer:

The molar mass of the compound given is 182.182 g/mol.

Explanation:

To calculate the molar mass of the compound, we must multiply the number of moles of each element by the the individual molar mass of each element and add them together.

Let's start with Calcium.  The molar mass of Calcium is 40.078.  In this compound, we have three moles of Calcium, so we should multiply this number by 3.

40.078 g/mol * 3 mol = 120.234 g

Now, let's do the same for Phosphorus.

30.974 g/mol * 2 g/mol = 61.948 g

To find the molar mass of the entire compound, we should add these two values together.

120.234 g + 61.948 g = 182.182 g

Therefore, the correct answer is 182.182 g/mol.
