<u>Answer:</u> The correct answer is
<u>Explanation:</u>
Aluminium is the 13th element of the periodic table with electronic configuration of
This element looses 3 electrons and shows an oxidation state of +3.
Oxygen is the 8th element of the periodic table with electronic configuration
This element will gain 2 electrons and shows an oxidation state of -2.
By criss-cross method, the oxidation state of aluminium and oxygen gets revered and they form the coefficients of the compound.
Hence, the compound formed will have the chemical formula of

Answer:
Explanation:
Hola,
En este caso, podemos usar la ley de Boyle, la cual nos permite analizar el comportamiento volumen-presión en un gas ideal de manera inversamente propocional:
Así, dado el volumen y la presión inicial, la cual se convierte a atmósferas (760 torr = 1atm), calculamos el volumen final a 1 atm como se muestra a continuación:
