properties of plasma

A

99.9 percent of matter in the universe is made of plasma
has an indefinite shape and an indefinite volume.
plasma has an electrical charge.
Most of the plasma in the universe is found within stars.

Q

The particle theory

A

1 all matter is made of tiny particles
2 particles have empty spaces between them
3 particles are moving randomly all the time
4 particles move faster and spread farther
apart when they are heated
5 particles attract each other

Q

Soluble vs. Insoluble

A

Soluble: the solute is capable of dissolving in a certain solvent
Insoluble: the solute isn’t able to dissolve certain solvent

Q

Classifying solutions

Qualitative

A

Concentrated : contains a large amount of solute and very little solvent.

Dilute: has very little solute dissolved into the solvent

17
Q

Quantitative

A

the exact amount of solute dissolved into a solvent

18
Q

Saturation

A

All solutions have a maximum amount of solute that will dissolve into a given amount of solvent at a given temperature.

19
Q

Unsaturated vs. Saturated vs. Supersaturated

A

A saturated solution is one that has been formed using the maximum amount of solute that will dissolve into a solvent, without adding more solvent or changing the temperature of the solvent.

A saturated solution can be cooled to a temperature where it forms a supersaturated solution, which contains more solute than would normally dissolve in the solution.

20
Q

Solubility and the Particle Theory

A

Particles have forces of attraction between them, and that they are in constant motion.
This means that in a solution, solute particles are bumping against other solute particles and solvent particles as well.

21
Q

Calculating Concentration

A

mass of solute (in grams)
Concentration = ————————————–
100 mL of solution

22
Q

Solubility formula

A

maximum mass of solute that will dissolve
(in grams)
Solubility = ————————————————
100 mL of solvent at a
certain temperature
