(a)[1]
Construct an equation to show the reaction of copper with oxygen.
(b)[1]
Name the main component of the gas that remains in D at the end of the experiment.
(c(i))[3]
Plot the results and draw a straight line of best fit.
(c(ii))[1]
Ring the anomalous point.
(c(iii))[1]
Use your graph to deduce the correct final volume of gas for the anomalous point.
(c(iv))[1]

(d(i))[1]
What is the final volume of gas if the student uses $25.0\,\text{cm}^3$ as the initial volume of air?
(d(ii))[1]
If the final volume of gas is $35.0\,\text{cm}^3$, what original volume of air does the student use?
