Question 1

What is the main principle of the Law of Conservation of Mass?

  • Mass is created during reactions
  • Mass is conserved during reactions
  • Mass is lost during reactions

💡 Hint: Think about examples where mass remains the same.

Question 2

True or False: The mass of reactants in a chemical reaction can be different from the mass of the products.

  • True
  • False

💡 Hint: What does conservation mean in terms of mass?

Challenge Problems

Push your limits with challenges.

Question 1

A reaction occurs where 10g of sodium and 20g of chlorine gas produce sodium chloride. If the mass of sodium chloride produced is found to be 29g, evaluate whether this reaction follows the Law of Conservation of Mass.

💡 Hint: Check if your addition of the reactant masses equals the product mass.

Question 2

You burn 5g of wood which produces ash and gases. If the ash weighs 2g after the reaction, discuss where the rest of the mass went and how it relates to conservation of mass.

💡 Hint: Consider all outputs and where they could go post-reaction.
