Conservation of Mass Practical
Name:
1. State the law of conservation of mass
2. Identify the type of reaction occurring when Copper carbonate is heated
3. Write a word equation to represent the changes that would occur
4. Write a balanced chemical equation for this reaction
5. How could you use this reaction to demonstrate the law of conservation of mass?
6. What measurements would you need to take before and after?
7. What safety things do you need to consider?
8. Carry out the practical and record your results here
9. Account the observed change in mass using the law of conservation of mass.
Mass and Moles practical.
Name:
You have been supplied a selection of samples of elements and compounds.
The aim of this practical is to determine the number of moles, and number of atoms present of each
of the samples by weighing the mass of them and using the Molar Mass.
Write down the key formulae you will need in order to calculate the unknowns.
Draw a table that will allow you to record the mass, molar mass, number of moles and number of
total atoms in each sample.
