The following question is about carbon dioxide.

a. Name and give the formula of each of the substances A, B and C.

b. Identify by name the different pieces of apparatus D, E, F and G.

c. Draw and label the apparatus that should be used if a dry sample of carbon dioxide gas was required.

d. When a gas jar containing carbon dioxide is held over a burning wooden splint and the cover removed, the flame goes out. State two properties of carbon dioxide illustrated by this observation.

e. Carbon dioxide is also produced when zinc carbonate is heated strongly.

(i) Write a balanced chemical equation for the reaction taking place.

(ii) Name the process which is taking place as the zinc carbonate is heated.

(iii) Calculate the volume of carbon dioxide that would be produced (measured at room temperature and pressure (rtp)) if 12.5 g of zinc carbonate were heated strongly.

(One mole of any gas occupies 24 dm3 at rtp. Ar: C = 12; O = 16; Zn = 65)
