4 Activity 3.11 | Chemistry Form

The primary goal of Activity 3.11 is to teach students how to represent chemical reactions systematically . By the end of this activity, you should be able to:

By measuring the (which equals the mass of oxygen lost), and the final mass of copper , we can calculate the mole ratio of Cu : O. chemistry form 4 activity 3.11

By heating a hydrated salt like CuSO₄·xH₂O (blue → white), you measure mass loss (water evaporated). The calculation principle is identical to Activity 3.11: The primary goal of Activity 3
