Answer:
Oxygen has 8 neutrons
Explanation:
We know that cause the atomic number says how many protons does the element has, so in this case is eight, and in the mass number, we have the number of protons+neutrons, in this case is 16. Then, as we know that oxygen has eight protons with the atomic number, we would do 16-8 protons= 8 neutrons.
Check: Atomic number is 16= 8 protons + 8 neutrons
Answer:
approximately 106 grams
Explanation:
The molecular mass of Aluminum Oxide is approximately 102 grams per mole.
2×Al=
2×27=54
3×O=3×16=48
54+48=102
200
102
=1.96 moles
There are two atoms of Aluminum in one mole and each atom has a mass of approximately 27 grams so
Mass of Al = 1.96×2×27=106 grams

Ionization is a formation of ions from neutral atoms or molecules.
SO₂ + H₂O = HSO₃⁻ + H⁺
Mg(OH)₂ = Mg²⁺ + 2OH⁻
Answer:
- Oxido de magnesio
Explanation:
Mg → magnesio
O → oxígeno
La unión del oxígeno (no metal) con un metal, forma el determinado óxido que se nombra como óxido de .... y el no metal.
En este caso, podemos deducir que el contenido del frasco es de óxido de magnesio, aunque viendo que hay un sólo átomo de oxígeno podemos llamarlo como monóxido de magnesio, similar al CO (monóxido de carbono).
A partir de que el magnesio sólido entre en contacto con el aire, se produce MgO de acuerdo a la siguiente reacción:
2Mg + O₂ → 2MgO
