the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
Answer:
<em>Leptón</em>
<em></em>
Explanation:
Lepton son partículas elementales de espín de medio entero (espín 1⁄2), y se sabe que no experimentan interacciones fuertes. Los leptones se clasifican en leptones cargados (los leptones similares a los electrones) y leptones neutros (conocidos como neutrinos). Un electrón es un leptón. Los leptones cargados pueden combinarse con otras partículas para formar átomos compuestos de partículas y positronio, mientras que los neutrinos rara vez interactúan con algo, lo que los hace raros de observar.
<em>Dado que la electricidad es el resultado del movimiento o flujo de electrones, la única partícula representativa de esta fuerza es el leptón.</em>
Balance the chemical equation by adding coefficients as needed. equation:
4HCl + -1As2O3 + 4NaNo3 + -5H2O → 12No + -2H3AsO4 + 4NaCl
Chemical Equation
A chemical equation is a symbolic representation of a chemical reaction in the form of symbols and formulae, where the reactant entities are given on the left and the product entities are given on the right, with a plus sign separating the entities in both the reactants and the products and an arrow pointing in the direction of the products to indicate the reaction's direction. The absolute values of the stoichiometric numbers are shown as coefficients next to the symbols and formulas of the entities. Jean Beguin drew the first chemical equation in 1615.
