What is Combustion Reaction?
Something that has the ability to burn.
What is oxidation reaction?
No flame appears
CH4 + O2 = CO2 + H2O
Methane + Oxygen = Carbon dioxide + Water
Iron + oxygen = ironoxide
Fe + O2 = Fe2O3
What is Lithium’s symbol?
Li

Na
What is phosphorus’ symbol?
P
What is iron’s symbol?
Fe
What is potassium’s symbol?
K
What is hydrochloric acid’s symbol
Hcł
What is particle theory?
Substances that are made up of particles.
Particles are always in motion.
Forces of attraction in between particles.
Empty space between particles.
For example,
Solid to liquid- motion increases, seperate, expansion, weaker attraction and forces.
What are the three types of mixtures?
Homogeneous- you can’t see the different components
Heterogenous- you can see components without a microscope.
Colloids- looks like a homogenous but components can be seen through a microscope.
