5 types of reactions
Formation, single Decomposition, double, combustion or oxidation
precipitations are
any liquid or frozen water that forms in the atmosphere and falls back to the Earth's surface
closed system
a physical setup or reaction vessel that prevents the transfer of matter while allowing energy (like heat or light) to move freely in and out
open system
Thermodynamic, the exchange of substances between the system and its surroundings
Formation=
Element+element=compound
eg: H2+02= 2H2O
Single decomposition
Compound—-> el+ el
Single replacement
A+BC= AC+B
What do cations and anions switch with
Their own charge
eg: Sodim would switch with calcium like how oxygen would switch with carbon
Neutralization reactions (acid + base mix)
Usually oroduce water or ionic compounds as a product
Precipitation
Produce low solubility compounds and one high
Precipitate
an insoluble solid that forms and separates from a liquid solution during a chemical reaction
(eg:Water droplets or ice crystals in clouds grow heavy and fall because of gravity)
g/mol (M) equals
Mass/mol (m/n)
m (mass)=
nM (mol x g/mol)
n (mole)
mass/molar mass (m/M
Ammonia=
NH3 gas
Methane
CH4
Which groups (bonded with polyamorous ions) are always aqueous
Alkali metals, group 1
Glucose
C6H12O6
Sucrose
C12H22O11
Ethane
C2H6 gas
Propane
C3H8 gas
Oxolate

Note for polyatomic elements
If left alone as an element, make sure to include the numbers next to it and times 1 molar mass of the element by how many times it bonds by itself
