Question

some soluble compounds are listed in the table below. complete the table by filling in the name or chemical formula of each compound, whichever is missing. (if there is more than one way to name the compound, choose the name used when the compound is dissolved in water.) also classify the compound using the checkboxes.

compound	name	type of compound (check all that apply)
hi		ionic molecular strong acid weak acid strong base weak base
nh₃		ionic molecular strong acid weak acid strong base weak base
	barium hydroxide	ionic molecular strong acid weak acid strong base weak base

Explanation:

Step1: Identify formula for potassium chloride

Potassium has a +1 charge ($K^+$) and chloride has a -1 charge ($Cl^-$), so the formula is $KCl$. It is an ionic compound.

Step2: Name HI

$HI$ is hydroiodic acid. It is a strong acid and a molecular compound.

Step3: Name $NH_3$

$NH_3$ is ammonia. It is a molecular compound and a weak base.

Step4: Identify formula for barium hydroxide

Barium has a +2 charge ($Ba^{2+}$) and hydroxide has a -1 charge ($OH^-$), so the formula is $Ba(OH)_2$. It is an ionic compound and a strong base.

Answer:

compound	name	type of compound (check all that apply)
$HI$	hydroiodic acid	molecular, strong acid
$NH_3$	ammonia	molecular, weak base
$Ba(OH)_2$	barium hydroxide	ionic, strong base
