10 Dilute hydrochloric acid reacts with calcium carbonate to produce carbon dioxide.(a) (i) With the aid of a diagram, design and describe an experiment in a laboratory to show how the rate of reaction between these two substances depends on the particle size of calcium carbonate.[4](ii)...
46. When powdered calcium carbonate reacts with dilute hydrochloric acid, the carbon dioxide gas is produced. If the complete reaction of calcium carbonate with dilute hydrochloric acid produces a maximum volume of 30cm3of carbon dioxide gas in 100 seconds, what is the average rate of this react...
