Observations Element Reaction with water X Y Z of Elements X, Y, and Z in Water and Acid Reaction with acid no evidence of chemical change many bubbles observed bubbles observed no evidence of chemical change bubbles observed no evidence of chemical change Analysis (a) In what order would these elements appear in the activity series? (2K, 3T) (b) Relate the position of each of the elements to that of hydrogen in the activity series. Which of the three elements is most likely to be hydrogen? Use the empirical evidence to justify your choice. Provide a theoretical rationale for your choice. (4T, 2C) Synthesis (c) In what order would X and Y appear as you descend the group? In what order would Y and Z appear as you move from left to right within the same period? Justify your answers, using empirical and theoretical knowledge. (4K) (d) You are told that X and Y are in Group 1 and that Y and Z are consecutive elements in Period 3. Write balanced chemical equations representing each reaction that took place. (2K, 3C) (e) Classify each of the reactions in part (d). Suggest a diagnostic test that you could use to support your classification.

Answer rating: 100% (QA)

a The order of the elements in the activity series is determined by their relative reactivity with water and acid Based on the observations provided i... View the full answer
