Answer:
Explanation:
Hello there!
In this case, according to the given information it will be firstly necessary to set up the chemical equation taking place:
We infer we need to calculate the moles of NH3 by using both of the moles of N2 and H2 at the beginning, in order to identify the limiting reactant:
Thus, since hydrogen yields the fewest moles of ammonia, we conclude that we are just able to yield 4 moles of NH3.

Answer:
loses, gains
Explanation:
In the ionic compound aluminum selenide, each atom of aluminum will lose electrons while each atom of selenium will gain the electrons.
An ionic compound is an interatomic bond formed between a metal and non-metal. The metal is less electronegative compared to the non-metal. In this case, the metal will lose electrons to become positively charged whereas the non-metal, selenium will gain the electron to become negatively charged.
The electrostatic attraction between these oppositely charged ions leads to the formation of the ionic bond.
