13 question (2 points)\nprovide the systematic name for the following ionic compounds.\n1st attempt\npart 1 (0.7 point)\nk₃po₄\npart 2 (0.7 point)\nca(no₃)₂\npart 3 (0.7 point)\ncr₃(po₄)₂
Answer
Explanation:
Step1: Identify cations and anions for $K_3PO_4$
$K^+$ is potassium ion, $PO_4^{3 - }$ is phosphate ion.
Step2: Name the compound
The name is potassium phosphate.
Step3: Identify cations and anions for $Ca(NO_3)_2$
$Ca^{2+}$ is calcium ion, $NO_3^-$ is nitrate ion.
Step4: Name the compound
The name is calcium nitrate.
Step5: Identify cations and anions for $Cr_3(PO_4)_2$
$Cr^{2+}$ is chromium(II) ion (as charge - balance with $PO_4^{3 - }$ requires +2 charge on Cr), $PO_4^{3 - }$ is phosphate ion.
Step6: Name the compound
The name is chromium(II) phosphate.
Answer:
Part 1: potassium phosphate Part 2: calcium nitrate Part 3: chromium(II) phosphate
