write the formulas for these compounds: perbroomic acid, magnesium phosphate

Sagot :

Answer:

Perbromic Acid: [tex]\mathrm{HBrO_4}[/tex]

Magnesium Phosphate: [tex]\mathrm{Mg_3(PO_4)_2}[/tex]

Perbromic Acid:

In Perbromic Acid, there exists 4 oxygen atoms to 1 bromine atom. Acids with per as prefix have a hydrogen atom attached. Therefore the chemical formula for Perbromic Acid is [tex]\mathrm{HBrO_4}[/tex].

Magnesium Phosphate:

Magnesium Phosphate is an ionic compound containing magnesium (Mg2+) and the phosphate ion (PO4 3-). In order to balance these charges to create the ionic compound, there must be 3 magnesium ions for every 2 phosphate ions to create the ionic compound. Therefore, the chemical formula for Magnesium Phosphate is [tex]\mathrm{Mg_3(PO_4)_2}[/tex].
