An identification of the atoms is a molecule (APEX)
A chemical formula shows the atoms and their respective quantity in a compound or molecule. The chemical formula CO2 reads as carbon, one atom, oxygen, two atoms. Another example is H2O (water).
A chemical reaction is something that happens between two chemicals when they interact.
A chemical formulae of a substance tells us the ratio of each atom in a compound
A stoichiometric equation is a notation that describes a chemical reaction using chemical formulae. An example is CH4 + 2 O2 -> CO2 + 2 H2O
formulae of tearing gas.
Their chemical formulae are HNO3 and H2SO4 respectively.
composed mostly of calcite (a crystalline form of calcium carbonate, CaCO3).
Answer 1CH4
An atom is what makes up chemical formulae. Just look at the periodic table -- those are your chemical formulae for atoms. Can be from H to Uuo.
H2
The chemical formula of water is H2O.
HCl
KOH
H2s2o8
NaHCO3
AgNO3
It is butane.
