Answer: Concentration

Explanation: Concentration is the amount of a solute that is contained in a given volume of a solution.

Dilution is the addition of solvent to a solution to make the solution less concentrated.

Molarity is the number of moles of a solute per litre of a solution. It is the concentration of a solute in a given volume of a solution.

A solvent is a substance in which other substances dissolve to form a solution.

Oxygen gas is collected at a pressure of 123 kPa in a container which has a volume of 10.0L. What temperature must be maintained
Morgarella [4.7K]
Given:

P = 123 kPa
V = 10.0 L
n = 0.500 moles
T = ?

Assume that the gas ideally, thus, we can use the ideal gas equation:

PV = nRT

where R = 0.0821 L atm/mol K

123 kPa * 1 atm/101.325 kPa * 10.0 L = 0.500 moles * 0.0821 Latm/molK * T

solve for T 

T = 295.72 K<span />

Pavlova-9 [17]

Answer:

D. A compound can be separated into two or more elements through a chemical reaction.

Explanation:

By method of elimination, we are going t obtain the correct  option.

A. A compound is made up of a single atom.

This is wrong because, a compound can contain more than one atom.  An example is H2O

B. A compound is made up of many atoms that are all the same type.

This is wrong because a compound can contain atoms of different elements. An example is H2O. It contains atoms of hydrogen and oxygen.

C. A compound can be separated into two or more elements through physical processes.

This is wrong. H2O being a compound cannot be separated by ordinary physical means.

D. A compound can be separated into two or more elements through a chemical reaction.

This is the correct option.
