Question

part d
enter the formula for the compound that forms from calcium and hydrogen phosphate.
express your answer as a chemical formula.
a chemical reaction does not occur for this question

Explanation:

Step1: Determine the charges of the ions

Calcium ion (\(Ca^{2+}\)) has a charge of \(+ 2\). Hydrogen phosphate ion (\(HPO_{4}^{2 -}\)) has a charge of \(-2\).

Step2: Use the criss - cross method

Since the magnitudes of the charges (\(2\) and \(2\)) are equal, the ratio of \(Ca^{2+}\) to \(HPO_{4}^{2 -}\) is \(1:1\).

Answer:

\(CaHPO_{4}\)
