Propiedades químicas del óxido​
tangare [24]

Óxidos básicos: Son formados por metales. El metal presente en su fórmula puede presentar carga eléctrica +1 y +2, o sea, poseer carácter iónico. Ejemplos: Na2O (óxido de sodio), BaO (óxido de bario).

Óxidos neutros: Son compuestos por no metales. No reaccionan con agua, ácido o base, en razón del enlace covalente que une sus componentes; de ahí el por qué de ser llamados óxidos inertes. Ejemplos: monóxido de dinitrógeno (N2O) y monóxido de carbono (CO).

Óxidos ácidos: También conocidos como anhídridos de ácidos, son formados por no metales y presentan carácter covalente. En la presencia de agua, producen ácidos y en la presencia de bases, origina sal y agua. Ejemplo: CO2 (dióxido de carbono o gas carbono) y el SO2 (dióxido de azufre)

Óxidos dobles o mixtos: La combinación de dos óxidos de un mismo elemento, da origen a este tipo de óxidos. Ejemplo: magnetita (Fe2O4), unión de los óxidos de hierro (Fe) y oxígeno (O).

Óxidos anfóteros: Presentan ambigüedad, en la presencia de un ácido se comportan como óxidos básicos y en la presencia de una base, como óxidos ácidos. Ejemplos: óxido de aluminio (Al2O3 ) y el óxido de zinc (ZnO).

Peróxidos: Compuestos que poseen en su fórmula el grupo (O2)2- . Los peróxidos más comunes son formados por hidrógeno, metales alcalinos y metales alcalinos térreos. Ejemplos: agua oxigenada (H2O) y peróxido de sodio (Na2O2).

Please help with 14-16 <br> Thank you!
Natalka [10]
I don't know about 14, but 15 is (4), because a liquid draws in heat to turn into a gas. 16 is (2), because to turn into a cold solid, something has to release heat.

Group 8A of the periodic table contains the A. most reactive nonmetals. B. least reactive nonmetals. C. most reactive metals. D.
aivan3 [116]

Answer: The correct answer is option B.

Explanation: There are 7 elements in group VIII-A. They are Helium (He), Neon(Ne), Argon(Ar), Krypton (Kr), Xenon (Xe), Radon (Rn) and Ununoctium (Uuo). They are considered as a part of group 18.

Metals are shown in purple color in the periodic table. Metalloids as blue color and Non-metals are shown in green color.

Group VIII-A elements have fully filled orbitals and hence are most stable amongst all the elements in the periodic table. They are considered as least reactive elements and as they are categorized as non-metals. So, they are the least reactive non-metals.

Therefore, the correct option is B.
