Double Replacement Reactions

Which of the following is an example of a double-replacement reaction?

• 4Co + 3O₂ → 2Co₂O₃

• MnSO₄ → MnO + SO₃

• Cd + 2HCl → CdCl₂ + H₂

• 2NaNO₃ + MgCl₂→ 2NaCl + Mg(NO₃)₂

In this equation,

CuCl₂+ NaOH → Cu(OH)₂ + NaCl

Which product is insoluble?

• copper(II) hydroxide

• sodium chloride

• sodium hydroxide

• copper(II) chloride

Predict the product(s) of the following reaction

• CO₃NO₃

Predict the products for the this reaction:
AgNO₃ + KCl --> 

• AgCl + KNO₃
• AgK + ClNO₃
