Question

determine the chemical formula for each of the compounds. sodium perchlorate: potassium permanganate: calcium sulfate: lithium cyanide: licn

Explanation:

Step1: Identify ions for sodium perchlorate

Sodium ion is $Na^+$ and perchlorate ion is $ClO_4^-$. To balance charges, formula is $NaClO_4$.

Step2: Identify ions for potassium permanganate

Potassium ion is $K^+$ and permanganate ion is $MnO_4^-$. So formula is $KMnO_4$.

Step3: Identify ions for calcium sulfate

Calcium ion is $Ca^{2 +}$ and sulfate ion is $SO_4^{2-}$. Charges balance, formula is $CaSO_4$.

Answer:

sodium perchlorate: $NaClO_4$
potassium permanganate: $KMnO_4$
calcium sulfate: $CaSO_4$
lithium cyanide: $LiCN$
