24. \(Ca_{3}(PO_{4})_{2} + 6H_{2}O\)28.
29. \(Al(C_{2}H_{3}O_{2})_{3} + 3H_{2}O\)30.
Explicación
## Step 1The problem involves double replacement reactions, also known as metathesis reactions. In these reactions, the cations and anions of two different molecules switch places, forming two new compounds.## Step 2For the reaction \(Ca(OH)_{2} + H_{3}PO_{4}\), the calcium ion (Ca2+) from calcium hydroxide (Ca(OH)2) will replace the hydrogen ion (H+) in phosphoric acid (H3PO4). This results in the formation of calcium phosphate (Ca3(PO4)2) and water (H2O).## Step 3In the reaction
, the silver ion (Ag+) from silver nitrate (AgNO3) will replace the potassium ion (K+) in potassium chloride (KCl). This results in the formation of silver chloride (AgCl) and potassium nitrate (KNO3).## Step 4In the reaction \(Al(OH)_{3} + HC_{2}H_{3}O_{2}\), the aluminum ion (Al3+) from aluminum hydroxide (Al(OH)3) will replace the hydrogen ion (H+) in acetic acid (HC2H3O2). This results in the formation of aluminum acetate (Al(C2H3O2)3) and water (H2O).## Step 5In the reaction \(Al_{2}(SO_{4})_{3} + Ca_{3}(PO_{4})_{2}\), the aluminum ion (Al3+) from aluminum sulfate (Al2(SO4)3) will replace the calcium ion (Ca2+) in calcium phosphate (Ca3(PO4)2). This results in the formation of aluminum phosphate (AlPO4) and calcium sulfate (CaSO4).
