Chemical Change

A change in matter in which the substances that make up the matter change into other substances with different chemical and physical properties.
(Foaming, fizzing, temp change, color change, fire)

1

Physical Change

A characteristic of matter that you can observe or measure without changing the identity of the matter
(Changing the states of matter)

2

Endothermic

Chemical reactions that absorb thermal energy.

3

Exothermic

Chemical reactions that release thermal energy

4

Catalyst

Substances that increases the reaction rate

5

Inhibitor

Substance that decreases the reaction rate

6

Increase reaction rate

Surface area, concentration/pressure, tempeture

7

Synthesis

Two or more substances combine to form a new compound
Ca + O2 ➡️ CaO

8

Decomposition

One compound breaks down and forms two or more substances
AlCl3 ➡️ Al + Cl

9

Combustion

A chemical reaction in which substance combines with oxygen and releases energy
CH4 + O2 ➡️ CO2 +H2O

10

Single replacement

One element replaces another element in a compound
Mg + HCI ➡️ MgCl2 + H2

11

Double Replacement

Two or more substances switch, forming new compound
BaBr2 + Na2SO4 ➡️ BaSO4 + NaBr

12

Ca + O2 ➡️ CaO

2Ca + O2 ➡️ 2CaO2

13
