Term
What makes a mixture a solution?
Definition
a mixture is something which is not chemicaly bonded to another thing
Term
Where can solutions be found?
Definition
Solutions are found everywhere.
Term
What are the parts of a solution?
Definition
The solute and the solvent... You can tell them apart because; solute is: in a solution a substance that is dissolved in a solvent and the solvent is, in a solution, the substance that dissolves a solute and makes up the largest percentage of a solution.
Term
Compare and contrast acid, bases and salts.
Definition

compare: All are compounds that can be identified by their common properties. Both are reactive in nature. Salt can dissolve in water just like the other acids and bases in most cases.

contrast: acids have a pH of lower than 7. bases have a pH higher than 7. salts have a pH of 7. 

Term
What makes a substance an acid? Base? Salt?
Definition
Acids and bases are everywhere. They are used in everyday life, from the food we eat to the soap we use. Nearly every substance you see and use are acids or bases, except for pure water and salts. They are neither an acid nor a base, instead they are neutral.
Term
Identify when a chemical reaction takes place.
Definition
Chemical reactions take place when subtances are mixed together.
Term
What makes a mixture solution?
Definition
By taking 2 or more things and putting them together. For example, if you take Kosher salt and water, that would a mixture AND a solution. the solution would be SALTWATER and the mixture would be salt .
Term
What is an ionic bond?
Definition
It holds differently charged ions together.
Term
What is a covalent bond?
Definition
When atoms share electrons together it forms a bond.
Term
What are the four signs of a chemical reaction?
Definition
Bubbling, Change of color, Change of temperature, Gas formation.
Term
What are electrons?
Definition
A negatively charged part of an atom that spins around the atom's center.
Term

Term
What are the parts of a chemical equation?
Definition
There are four parts: reactants, yield signs, products, and the coeffiecients
Term
