Planning Aim: In this experiment I plan to experiment how the amount of zinc oxide produced is affected by the amount of calamine used. Hypothesis: I predict that the more calamine used the greater the amount of zinc oxide produced. This is because the equation of the reaction must have an equal amount on each side. The equation is ZnCOł ZnO+CO˛. From this it can be seen that for every atom of zinc contained in the calamine it produces the same number of atoms in zinc oxide. Therefore I hypothesise that there is a direct positive correlation and would expect the graph to show a straight line In a previous experiment where copper carbonate was obtained from malachite the results showed that as the more malachite was used the more product was produced. The relationship between the mass of malachite used and the amount of copper oxide obtained was proportional. Malachite and...
