write the chemical formula for copper (ii) phosphate.
your answer
write the name for h₂o. *
dihydrogen monoxide
what is the molar mass of luminol (c₈h₇n₃o₂)? *
177g/mol

Explanation:

Step1: Determine the ions

Copper (II) has a charge of \(Cu^{2+}\), phosphate has a charge of \(PO_{4}^{3 -}\).

Step2: Use charge balance

To balance the charges, find the least - common multiple of 2 and 3 (which is 6). So we need 3 \(Cu^{2+}\) ions (\(3\times2 = 6\)) and 2 \(PO_{4}^{3 -}\) ions (\(2\times3=6\)).

Answer:

\(Cu_{3}(PO_{4})_{2}\)
