Back 20

exothermic

Front 21

what is the law of conservation of mass

Back 21

no matter is created nor destroyed in a chemical or physical change

Front 22

what is activation energy

Back 22

the minimum amount of energy needed to start a chemical reaction

Front 23

what five factors can effect the reaction rates

Back 23

surface area, temperature, concentration, presence of catalysts, presence of inhibitors

Front 24

what is a chemical equation

Back 24

a way to show a chemical reaction, using symbols instead of words

Front 25

what is the structure of a chemical equation

Back 25

reactant + reactant (arrow) product + product

Front 26

a number placed in front of a chemical formula in an equation

Back 26

coefficient

Front 27

a single kind of matter that has a specific makeup, or composition

Back 27

pure substance

Front 28

two or more substances that are together in the same place, but their atoms are not chemically bonded

Back 28

mixture

Front 29

what are two types of mixtures

Back 29

heterogeneous, homogeneous

Front 30

a mixture in which you can see the different parts and can easily separate them

Back 30

heterogeneous mixture

Front 31

so evenly mixed that you can't differentiate the parts simply by looking at the mixture

Back 31

homogeneous mixture

Front 32

solids can be separated from liquids by pouring the mixture through a filter

Back 32

filtration

Front 33

iron objects can be separated from a mixture using a magnet

Back 33

magnetic attraction

Front 34

liquids can be separated from each other by heating them up to the temperature at which one of the liquids boils. The liquids boils into a gas. Then the gas cools, forming the separated liquid.

Back 34

distillation

Front 35

when left in the open air, liquid solutions can change to gas, leaving solid components behind

Back 35

evaportion

Front 36

part of a solution usually present in the largest amount. it dissolves the other substance

Back 36

solvent

Front 37

substance that is dissolved by the solvent

Back 37

solute

Front 38

what is the universal solvent

Back 38

water

Front 39

a mixture containing small, undissolved particles that do not settle out

Back 39

colloid

Front 40

mixture in which particles can be seen and easily separated by settling or filtration

Back 40

suspension

Front 41

factors that affects the solubility of a substance

Back 41

pressure, type of solvent, temperature

Front 42

any change that alters the form or appearance of a substance but does not change into another substance

Back 42

physical change

Front 43

a change in matter that produces one or more new substances

Back 43

chemical change

Front 44

substances that undergo the chemical change

Back 44

reactants

Front 45

a solid that forms from liquids during a chemical reaction

Back 46

precipitate

Front 47

amount of a substance in a given volume

Front 49

cell in your body contain thousands of biological catalysts called..

Back 49

enzymes

Front 50

a material used to decrease the rate of a chemical reaction

Back 50

inhibitor

Front 51

arrow that goes one way

Back 51

means reaction is one way (goes forward)

Front 52

arrow that goes both ways

Back 52

means reaction is reversible (can go forward and backward)

Front 53

surface area affects a chemical reaction by..

Back 53

the more particles exposed to the surface, the faster the reaction occurs

Front 54

temperature affects a chemical reaction by..

Back 54

higher temperatures make particles move faster so they have a better chance of coming into contact with each other quicker. lower temperatures make particles slow down, lowering the chances of them coming into contact quicker.

Front 55

concentration affects a chemical reaction by..

Back 55

increasing/ decreasing the concentration reactants supplies/lowers the supply of particles to react.
