What is a heterogeneous?
are composed of two or more components that are: unequally
What is a homogenerous?
are composed of two or more components that are: equally
What is a solution?
is a mixture of one substance dissolved in another so the properties are the same throughout.
What is a solute?
 is a substance that is dissolved into the solvent.
What is a solvent?
 is defined as the base substance, wherein the solute is being dissolved.
What is a concentrated?
a solution in which much of the water has been removed
What is a saturated?
 is a solution in which the solvent cannot dissolve any more solute to increase the concentration of the solution.
What is a unsaturated?
is a fat ir a fatty acid and which thier is a least have a double bond to the fatty chain

What is a supersaturated?

A solution which has reached saturation at a higher temperature
What is a acid, base, and salt?

Acid=a substance that yields hydrogen ions when dissolve in water

Base=

What are different properties?
of matter describes its “potential” to undergo some chemical change or reaction by virtue of its composition.
What is a neutralIzation?
is the basis of titration, where a pH indicator shows equivalence point when the equivalent number of moles of a base have been added to an acid.
What is a Ph Scale?
measures how acidic or basic a substance is. The pH scale ranges from 0 to 14
What is a indicators?
A way to measure, indicate, point out or point to with more or less exactness
What is a ionic compounds?
are basically defined as being compounds where two or more ions are held next to each other by electrical attraction.
What is a chemical change?
the substances are altered chemically and display different physical and chemical properties after the change.
What are the four signs?

1) color change
2) the formation of gas bubbles
3) formation of a precipitate
4) temperature change

What is a Exothermic?
An exothermic reaction is a reaction that releases heat.

What is a endothermic?
 is a chemical reaction in which energy (heat, light, etc.) is absorbed instead of being released as it is in a exothermic reaction.
What is a equation?
 says that two things are equal.
What is a The conservation of mass?
 the mass in a system that is closed will be constant.
What is Catalyst?
as a substance that increases the rate of a chemical reaction
