2

Acid

H

3

Base

OH

4

Acid vs base

Acid right base left

5

Endothermic

Take in more energy to break bonds

6

Exothermic

Give out more energy to make bonds

7

Law do conservation of energy

Energy cannot be created or destroyed it can only change forms

8

Physical properties

Can be observed without changing the identity of the substance

9

Physical property example

Multipoint viscosity density solubility hardness Luster malleability ductility

10

Physical change

They usually reversible change in the physical property of a substance change and state or phase

11

Chemical properties

Characteristic that's observed during a reaction and identity/chemical composition of the substance changes

12

Chemical property example

Flammability pH reactivity and toxicity

13

Chemical change

And irreversible on chemical reaction involving the rearrangement of atoms and a change in their chemical properties

14

Chemical change examples

Burning digesting cooking rust

15

Signs of the chemical reaction

Color change precipitation (solid forming from liquid) gas temperature change

16

Catalyst

Substance that increases the rate of a chemical reaction

17

Inhibitor

The substance that slows the prohibits a chemical reaction
Block entrance
Interact with catalyst to prevent from working

18

Equilibrium

A chemical reaction in which the forward and reverse reactions occur at equal rights
