Oxygen gas O2 is a compound, a molecule and a pure substance.

Oxygen gas is a compound because it contains more than one atom( two oxygen atoms) that are chemically combined together.

Oxygen gas is a molecule because it can exist independently as a unit and the oxygen atoms are covalently bound.

It is a pure substance because it contains only oxygen molecules.

Answer:

[tex]\boxed {\boxed {\sf B. \ 0.5 \ M}}[/tex]

Explanation:

Molarity is a measure of concentration in moles per liter. The formula for calculating molarity is:

[tex]molarity= \frac{moles \ of \ solute}{ liters \ of \ solution}[/tex]

There are 2 moles of a compound or the solute. There are 4 liters of water or the solution.

Substitute the values into the formula.

[tex]molarity = \frac{ 2 \ mol}{ 4 \ L}[/tex]

Divide.

[tex]molarity= 0.5 \ mol /L[/tex]

1 mole per liter is equal to 1 Molar, so the solution's molarity of 0.5 mol/L is equal to 0.5 M.

[tex]molarity = 0.5 \ M[/tex]

The molarity of the solution is 0.5 Molar and choice B is correct.

A. Domestic cats live in about 34% of homes in the United States. (Statistical statements are, most of the time, facts and not an opinion)

C. Modern domestic cats are closely related to Near Eastern wildcats. (Fact)

Answer:

32.4°C

Explanation:

Consider the following expression:

P•V/T =P'•V'/T'

Where P and P' are respectively the initial and the final pressure, V and V's are respectively initial and final volume, and T and T' are respectively initial and final temperature.

We know that the pressure cannot change, so it means that P = P'

We also know that the volume must be increased in 20%, and if we multiply the volume by 1.2 is like increase it in 20%, so we can write that V' = 1.2•V, and changing a little more we can write that V'/V = 1.2

So let's do some maths:

P•V/T = P'•V'/T'

T'•P•V/T = P'•V'

T'•P•V = P'•V'•T

T'=P'•V'•T/P•V

We know that P'=P so the division is equal to 1:

T'= 1•V'•T/V

We also know that V'/V = 1.2, so:

T' = 1.2•T

And we know the value of T, it's 27, so now we just have to solve it:

T' = 1.2•27

T' = 32.4°C
