P4Se3
The empirical formula of phosphorus bromide is PB3. This is derived by finding the simplest whole-number ratio of atoms in the compound.
Almost certainly you are looking for Titanium(IV) Selenide, TiSe2, though the Titanium(III) compound, Ti2Se3 may exist as well. You should be more specific :)
In this instance, the empirical formula is the same as the formula unit: NaNO3
The balanced equation for the reaction between cesium (Cs) and selenium (Se) to form cesium selenide (Cs2Se) is: 2Cs(s) + Se(s) -> Cs2Se(s)
The empirical formula for potassium manganate is KMnO4.
The empirical formula of phosphorus bromide is PB3. This is derived by finding the simplest whole-number ratio of atoms in the compound.
Sulfur and phosphorus would most like form the compound P2S5
P underscore 2 O underscore 3
titanium (II) selenide = SeTi
V2Se5 is the formula for vanadium V selenide.
The chemical formula for copper selenide is Cu2Se.
p2o5
The empirical formula for K3PO4 is K3PO4 itself. This is because the subscripts in the formula (3 for potassium, 1 for phosphorus, and 4 for oxygen) represent the simplest whole-number ratio of the elements in the compound.
The formula for titanium(II) selenide is TiSe.
The chemical formula for boron selenide is B2Se3.
Formula: CdSe
Formula: Se2-
