The product of a reaction between these two elements is .
Explanation:
The oxidation state of an ion in a compound is equal to its charge.
The aluminum having a charge of +3 because oxidation state is +3
The oxide is having charge of -2
The product of these reactants will produce a chemical compound.
The compound formed is i.e Aluminium oxide. The compound while getting formed will share the charge and cation A+ will have the charge of anion and anion will have the charge of cation. This will result in a compound as there should be a neutral charge on the compound formed.
The <em>+</em><em>3 charge of the cation Al+ will go to anion oxide O2- and the charge of anion -2 will go with cation Al+. </em>

There are several types of renewable resources that can be used in our home. Solar power, wind power, water power to name a few. The most reliable would most likely be water, since the winds don't always blow and the sun doesn't always shine, but water always flows.
Answer:
a. Exotérmica
b. Exotérmica
c. Endotérmica
Explanation:
- Las reacciones exotérmicas son aquellas que liberan calor al ambiente. Como consecuencia la temperatura final del sistema aumenta. Podemos reconocerlas porque el calor aparece como un producto.
- Las reacciones endotérmicas son aquellas que absorben calor del ambiente. Como consecuencia la temperatura final del sistema disminuye. Podemos reconocerlas porque el calor aparece como un reactivo.
a. La combustión del propano:
C₃H₈ (g)+ 5 O₂(g) ⇒ 3 CO₂(g) + 4 H₂O(g) + 531 kcal
La reacción es exotérmica por lo que el calor aparece como producto.
b. La formación de la sal de mesa:
2 Na(s) + Cl₂(g) ⇒ 2 NaCl(s) + 196 kcal
La reacción es exotérmica por lo que el calor aparece como producto.
c. La descomposición del pentacloruro de fósforo:
PCl₅(s) + 16 kcal ⇒ PCl₃(s) + Cl₂(g)
La reacción es endotérmica por lo que el calor aparece como reactivo.
