What are two actions that would cause an increase in relative humidity

Answers

Answer 1

Answer: relative humidity increases when the amount of moisture air can hold increases.The increase can be caused by the introduction of more moist air OR a temperature drop of the air/moisture mixture without a loss of moisture. Colder air will hold less moisture than warm air;as the temperature goes down the amount of moisture relative to what the air can hold increases

Answer 2

Answer:

Answer:

cooler air

How many moles of oxygen must be placedin a 3.00 L container to exert a pressure of 2.00 atm at 25.0°C?
Which variables are given?

Answers

0.24 moles of oxygen must be placed in a 3.00 L container to exert a pressure of 2.00 atm at 25.0°C.

The variables given are Pressure, volume and temperature.

Explanation:

Given:

P = 2 atm

V = 3 litres

T = 25 degrees or 298.15 K by using the formula 25 + 273.17 = K

R = 0.082057 L atm/ mole K

n (number of moles) = ?

The equation used is of Ideal Gas law:

PV = nRT

n = $(PV)/(RT)$

Putting the values given for oxygen gas in the Ideal gas equation, we get

n = $(2 x 3)/(0.082157 x 298.15)$

= 0.24

Thus, from the calculation using Ideal Gas law it is found that 0.24 moles of oxygen must be placed in a container.

Ideal gas law equation is used as it tells the relation between temperature, pressure and volume of the gas.

In a _______ mixture, the ingredients are distributed evenly throughout the mixture, while in a _______ mixture, the ingredients are unevenly distributed throughout.heterogeneous; homogeneous
heterozygous; homozygous
homozygous; heterozygous
homogeneous; heterogeneous

Answers

In a homogeneous mixture, the ingredients are distributed evenly throughout the mixture, while in a heterogeneous mixture, the ingredients are unevenly distributed.

The correct answer choice is the fourth one. You know this because you can eliminate the second and third choices since homozygous and heterozygous are terms more commonly used in genetics. And you can eliminate the first one because a homogenous mixture is more like a solution, where it is blended to where it looks like one substance. For example, pudding would be a homogenous mixture. So, homogeneous has to be in the first blank.

Answer:

homogeneous; heterogeneous

Is it true that the formula for magnesium sulfate shows that there are four atoms of sulfur

Answers

Magnesium sulfate is a compound made of three elements linked chemically. No, it is not true that magnesium sulfate has four sulfur atoms. Thus, the statement is false.

What is magnesium sulfate?

Magnesium sulfate has been a chemical compound that has a molecular formula of MgSO₄ and has been constituted of magnesium, sulfur, and oxygen atoms. It is used for medicinal purposes and as laxatives.

From the molecular formula of magnesium sulfate, it can be said that there are one atom of magnesium, one atom of sulfur, and four atoms of oxygen element. There will be four sulfur atoms only if there are 4 molecules of magnesium sulfate.

Therefore, the statement is false as there is one sulfur atom and four oxygen atoms in the magnesium sulfate compound.
