What is a mole(chemistry)?

  1. 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

200

A chemical equation where mass is conserved, showing equal numbers of each element's atoms on both sides.


Balanced equation

200

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.

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).
