expeople1 [14]

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

Boron has an average atomic mass of 10.81. One isotope of boron has a mass of 10.012938 and a relative abundance of 19.80 percen
Georgia [21]
The average atomic mass is calculated by the expression:

Average atomic mass = Σzₓ(Aₓ)

where zₓ is the relative abundance of an isotope and Aₓ is the atomic mass of the isotope. 

We calculate the mass of the isotope as follows:

10.81 = .1980 (10.012938) + .8020 (x)
x = 11.00 -----------> mass of the isotope
