Question

before moving on, try to name the following three compounds. pay attention to whether or not they contain polyatomic ions. caco₃ licl baso₄

Explanation:

Step1: Analyze the first compound

For \(CaCO_3\), \(Ca^{2 +}\) is calcium ion and \(CO_3^{2-}\) is carbonate ion (a polyatomic ion). So it is calcium carbonate.

Step2: Analyze the second compound

For \(LiCl\), \(Li^{+}\) is lithium ion and \(Cl^{-}\) is chloride ion (not a polyatomic ion). So it is lithium chloride.

Step3: Analyze the third compound

For \(BaSO_4\), \(Ba^{2 +}\) is barium ion and \(SO_4^{2-}\) is sulfate ion (a polyatomic ion). So it is barium sulfate.

Answer:

Calcium carbonate, Lithium chloride, Barium sulfate
