Answer:

Atom A: +2 Atom B: 0 Atom C: -4 Atom D: +4

Explanation:

We know that protons have a positive charge and electrons have a negative charge. Therefore, we will treat the electrons as a negative number. The net charge is the sum of electrons and protons.

Atom A = 6 + (-4)

because electrons as negative.

Net charge = +2

Atom B = 9 + (-9)

Net charge = 0, or neutral

Atom C = 10 + (-14)

Net charge = -4

Atom D = 33 + (-29)

Net charge = +4

Afirmar que el h20 es la formula que corresponde al agua, esto es una teoría, idea, ley, hipotesis o experimentación
frozen [14]

Answer:

Ley.

Explanation:

En la teoría de la ciencia, la regularidad de los procesos en la naturaleza se denomina ley de la naturaleza. Las leyes naturales se diferencian de otras leyes en que los seres humanos no pueden ponerlas en vigor ni anularlas a su discreción. En tal sentido, la composición química del agua es indudablemente una ley natural, en tanto el hombre no puede modificarla sin modificar las características inherentes del agua como tal.
