A chemical reaction representation showing reactants and products with formulas, separated by plus signs, and divided by a yield arrow.
Chemical equation
What is a mole(chemistry)?
a mole measures the amount of a substance, defined as 6.02214076×10^23 particles (atoms, molecules, ions, or electrons), known as Avogadro's number. It helps chemists count entities in a substance's mass.
Atom?
An atom is the smallest unit of an element, consisting of a central nucleus of protons and neutrons, surrounded by electrons.
is this equation equal?
2H+O -> H2O
yes
A chemical equation where mass is conserved, showing equal numbers of each element's atoms on both sides.
Balanced equation
The molar mass of a substance is the mass of one mole, measured in grams per mole (g/mol). For an element, it equals the atomic mass in atomic mass units (amu). For a compound, it is the sum of the molar masses of its elements.
Molar mass
Ion?
An ion is an atom or molecule with a net positive or negative charge due to losing or gaining electrons. Losing electrons forms a positive ion (cation), while gaining electrons forms a negative ion (anion).
Is this equation Balanced.
C+O -> CO2
no
A chemical equation showing only the reactant and product formulas without coefficients.
Skeleton equations
A mole ratio is a conversion factor from a balanced chemical equation that relates the moles of any two substances. For example, in 2H₂ + O₂ → 2H₂O, the mole ratio of H₂ to O₂ is 2:1.
