Question

type the charge of the each ion, then type the name of each compound below: cucl3 cu ? cl ? the name of this chemical is: (remember to include the roman numeral) crp cr ? p ? the name of this chemical is: (remember to include the roman numeral)

Explanation:

Step1: Determine the charge of ions in \(CuCl_3\)

• Chloride ion (\(Cl\)) has a charge of \(-1\). Let the charge of \(Cu\) be \(x\).
• In \(CuCl_3\), using the rule that the sum of charges in a neutral compound is zero: \(x+3\times(- 1)=0\).
• Solving for \(x\): \(x - 3=0\), so \(x = +3\). The name of \(CuCl_3\) is copper(III) chloride.

Step2: Determine the charge of ions in \(CrP\)

• Phosphide ion (\(P\)) has a charge of \(-3\). Let the charge of \(Cr\) be \(y\).
• In \(CrP\), using the rule that the sum of charges in a neutral compound is zero: \(y+(-3)=0\).
• Solving for \(y\): \(y=+3\). The name of \(CrP\) is chromium(III) phosphide.

Answer:

For \(CuCl_3\): \(Cu^{3 +}\), \(Cl^{-}\), copper(III) chloride.
For \(CrP\): \(Cr^{3+}\), \(P^{3 -}\), chromium(III) phosphide.
