7. The following observations were made during a chemical reaction involving three unknown metals. Analyse the table here to help you answer the questions that follow: X Y N Metal Reaction with water no reaction no reaction no reaction Reaction with vinegar Small bubbles formed on the surface of the metal rapid production of bubbles on the surface of the metal no reaction Reaction with hydrochloric acid immediate, rapid production of bubbles on the surface of the metal; the entire piece of metal had reacted within 5 minutes a large amount of gas was immediately produced and the entire piece of metal reacted within 1 minute some bubbles were observed on the surface of the metal after 2 minutes a) List the metals in order from most reactive to least reactive. b) Write a short statement justifying your answer to part (a). c) If all of the metals were located in the same period on the periodic table but in different groups, which would have the highest group number? Explain your answer with a short statement related to periodic trends.
