Answer the following questions from Periodic Trends - Alkaline Earth Metals Lab in a clear and concise manner.
1. In the Metal reacting with water section, what observation indicated that a reaction occurred? What is the name of this product?
2. You add an solution to the water into order to observe that a chemical reaction occurred. What is this chemical and what does it indicate?
3. From your data table and knowledge of this lab, was Calcium or Magnesium more reactive with water? Explain.
4. If your teacher "demo" the reactions of Lithium, Sodium and Potassium with water, was there any other observation of a chemical reaction that occurred in one or all of these reactions? Were the main products of the reactions changed comparing Calcium/magnesium to Lithium/sodium/potassium?
If your teacher did not "demo" the reaction, just write "Teacher did not demo" for this question.
5. How does the reactivity of the Alkaline Earth Metals changes as you go down the Group? What observation(s) are you using to explain the reactivity difference?
6. From your knowledge of the Periodic Trends, support your answer to Question 5 (Q5) above using your knowledge of the properties of the 6 Periodic trends.
7. How does the Group 1 (Alkali metals) and Group 2 (Alkaline Earth Metals) compare in reactivity with water (include the specific elements that you used in your explanation.
8. From your knowledge of the Periodic Trends, support your answer to Question 7 (Q7) above using your knowledge of the properties of the 6 Periodic trends.
9. For the solubility of the sulfate section, list the different sulfates from most soluble to least soluble. What observation(s) indicated how you listed the elements.
10. From your knowledge of the Periodic Trends, support your answer to Question 9 (Q9) above using your knowledge of the properties of the 6 Periodic trends.
