An ionic compound is formed by exchange of valency between bonding ions.
The formula of an ionic compound formed from O2− with;
Magnesium ion has a charge of 2+ and oxygen ion has a charge of 2-, when the two are combined, we obtain a compound of formula MgO.
Sodium ion has a charge of +1 and oxygen ion has a charge of 2-, when the two are combined, we obtain a compound of formula Na2O.
Aluminium ion has a charge of +3 and oxygen ion has a charge of -2, when the two are combined, we obtain a compound of formula Al2O3.

Answer:
2Ga2O3 = 4Ga + 3O2
Explanation:
You need to balance out the equation by making sure there are the same number of elements on each side.
Ga - 4 on each side
O - 6 on each side
Answer:
x = 2.37
Explanation:
ln x = 0.863
apply e to both sides of the equation:
e^(ln x) = e^0.863
e^(ln x) = x = e^0.863
{Demonstration of e^(ln x) = x:
y = e^(ln x)
apply ln to both sides of the equation:
ln y = ln (e^(ln x))
apply logarithmic property (ln xⁿ = n ln x)
ln y = ln x * ln e (ln e = 1)
ln y = ln x
Then:
y = x
Because y = e^(ln x) and x = y, then:
x = e^(ln x)
End of the demonstration }
Returning to our equation:
e^(ln x) = e^0.863
Then,
x = e^0.863 = 2.37
From what I would think, it is D.
The two compounds present
in unpolluted air are carbon dioxide and water. You may think that carbn
dioxide is a greenhouse gas, yes it is and at the same time not. There animals
in the earth that produces carbon dioxide into the atmosphere, the carbon
dioxide too, is also need for plan respiration.
