Chemistry formulas to memorise :)

with brain rot

hydroxide

OH^-

note: hydrogen has only 1 electron idk.

oh! -1 aura

nitrate

NO₃^-

note: 3 oxygens

-1 aura for being no

hydrogencarbonate

HCO₃^-

note: the long one is -1 idk

-1 aura for being so long

carbonate

CO₃^2-

note: carbon has a valency of -2

-2 aura bc there are 2 more oxygens than carbons

sulfate

SO₄^2-

note: sulfur has a valency of -2

-2 aura idk bc its in so many questions in the book

the best formula

phosphate

PO₄^3-

note: phosphorus has a valency of -3

-3 aura for having the worst name and having 3 more oxygens than phosphoruses

wishes it could be SO₄ lmao

methane

CH₄

note: channel 4

ammonia

NH₃

note: no homo -3 aura

hydrochloric acid

HCl

note: its an acid but it has a basic formula

nitric acid

HNO₃

note: 3 bc there are 3 elements idk

sulfiric acid

H₂SO₄

note: SO₄ the coolest formula

just sulfate with 2 hydrogens

phosphoric acid

H₃PO₄

note: just 3 hydrogens with phosphate

comes after sulfiric acid

3 4

acid + reactive metal →

salt + hydrogen

acid + base (metal oxide or metal hydroxide) →

salt + water

acid + carbonate or hydrogencarbonate →

salt + carbon dioxide
