• Decomposition

• Combustion

• Synthesis

• Single Replacement

What are the correct formulas and coefficients for the products of the following single-replacement reaction?
Mg + Al(OH)₃ →

• No Reaction
• Al + Mg(OH)₃
• 2 Al + 3 Mg(OH)₂
• 3 Al + MgOH₃

Write a balanced equation for this Double Displacement reaction
NaOH + Fe(NO₃)₃ -->

• NaFe + OH(NO₃)₃
• 2NaNO₃ + 3Fe(OH)₃
• NaNO₃ + FeOH
• 3NaNO₃ + Fe(OH)₃

Which of the following is a product of the equation:

AgNO₃ + MgCl₂ =>

• AgMg

• NO₃Cl₂

• MgNO₃

• Mg(NO₃)₂

#5. Balance the chemical equation, just balance:

C₆H₁₂O + O₂ → CO₂ + H₂O

• 2C₆H₁₂O + 17O₂ → 12CO₂ + 12H₂O

• C₆H₁₂O + 9O₂ → 6CO₂ + 6H₂O

• C₆H₁₂O + 7O₂ → 6CO₂ + 2H₂O

• 2C₆H₁₂O + 17O₂ → 6CO₂ + 6H₂O

#7. Predict and balance the equation:

P₄ + O₂ -->

• P₄ + 3O₂ --> 2P₂O₃

• P₄ + 2O₂ --> 4PO

• P₄ + O₂ --> P₄O₂, balanced

• P₄ + 4O₂ --> 2P₂O₄

#6. Balance the chemical equation, just balance:

Cu(OH)₂ + HC₂H₃O₂ --> Cu(C₂H₃O₂)₂ + H₂O

• Cu(OH)₂ + 2HC₂H₃O₂ --> Cu(C₂H₃O₂)₂ + 2H₂O

• 2Cu(OH)₂ + 2HC₂H₃O₂ --> 2Cu(C₂H₃O₂)₂ + 2H₂O

• 2Cu(OH)₂ + HC₂H₃O₂ --> 2Cu(C₂H₃O₂)₂ + H₂O

• Cu(OH)₂ + HC₂H₃O₂ --> Cu(C₂H₃O₂)₂ + H₂O

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

• 1

• 2

• 3
