Predicting Double Replacement Products

An acid/base reaction is a specific type of ___ reaction.

• Decomposition

• Synthesis

• Combustion

• Single Replacement

• Double Replacement

Answer explanation

Reactants: A hydrocarbon and oxygen

Products: water and carbon dioxide

The cations in two compounds switch. 

• Synthesis

• Combustion

• Single Replacement

• Double Replacement

Answer explanation

Reactants: 2 compounds

Products: 2 new compounds

Ex: AB + CD --> AD + CB

Predict the products, before balancing.

Co₂(SO₄)₃ + NaOH -->

• CoOH + NaSO₄

• CoNa + OH(SO₄)₃

• Co₂OH + Na(SO₄)₃

• Co(OH)₃ + Na₂SO₄

• no reaction

in a reaction, aqueous barium chloride reacts with aqueous potassium carbonate to produce solid barium carbonate and aqueous potassium chloride. what is the correct balanced equation.

• Ba₂Cl_(aq) + KCO_3(aq) --> BaCO_3(s) + KCl_(aq)

• BaCl_2(aq) + K₂CO_3(aq) --> BaCO_3(s) + 2KCl_(aq)

• BaCl_(aq) + K₂CO_3(aq) --> BaCO_3(s) + K₂Cl_(aq)

• Ba₂Cl_2(aq) + KCO_3(aq) --> Ba₂CO_3(s) + KCl_2(aq)
