Y11 Reacting Mass Questions 5 and 6.
Both of these involve reactions with hydrochloric acid and both involve interpretations from a graph, where kinetics is also tested. Question 5 looks at the reaction between CaCO3 and HCl and then determines the identity of M in M(OH)2. Question 6 looks at the reaction between Mg and HCl. Note that 9min30s into the snapkast I wrote the formula CaCl2 where I should have written CaCO3.
