Answer:
NH3
Explanation:
In solution, they are in equilibrium. NH4+ acts as a bronsted Lowry acid and donates an H to become NH3, and NH3 acts as a bronsted lowry base and accepts an H. In this pair, NH3 is a weak base, which gets its basic character due to the presence of lone pair of nitrogen and its ability to donate it.
Answer:
"Ar 3d3 4s2" is the electronic configuration for Vanadium.
To find the ratio of the the combination for the ion, write the charge of the cation as the subscript for the anion, and the charge of the anion as the subscript of the cation. This will make the charges effectively cancel and you will be left with a neutral ionic compound. Remember, that an ionic compound is made up of a metal and a nonmetal.
For Cr3+ and O2-, you will get the neutral compound to be Cr₂O₃.
The proportion these ions combine in is 2 to 3. 2 ions of Cr3+ and 3 ions of O2-
Your answer is D) 2:3

Answer:
Ions form when an atom gains or loses electrons in order to find a more stable configuration.There are two types of ions cations and anions
