Question 1

What does a balanced chemical equation represent?

  • The amount of reactants only
  • The conservation of mass
  • The energy changes during the reaction

💡 Hint: Think about what happens to atoms in a chemical reaction.

Question 2

True or False: The coefficients in a balanced equation tell us the number of moles of reactants and products.

  • True
  • False

💡 Hint: Consider the role of coefficients in a balanced reaction.

Challenge Problems

Push your limits with challenges.

Question 1

If 5.00 g of aluminum reacts with excess chlorine gas to form aluminum chloride (AlCl₃), calculate the theoretical yield of AlCl₃. Assume complete reaction.

💡 Hint: Start with the molar mass, then find how much AlCl₃ can be produced from the given Al.

Question 2

Calculate the limiting reagent and percent yield if 30.0 g of ammonium nitrate (NH₄NO₃) reacts with 40.0 g of sodium hydroxide (NaOH) to produce sodium nitrate (NaNO₃) and water. Write the balanced equation first.

💡 Hint: Divide the masses by their molar masses, then compare ratios to find the limiting reagent.
