14. A substance is found by analysis to contain 45.57% tin and 54.43% chlorine. What is the
empirical formula for the substance?
15. Aluminum sulfide reacts with water to form aluminum hydroxide and hydrogen sulfide.
a) Write a balanced equation for this reaction. b) How many grams of aluminum
hydroxide can be obtained from 5.50 g of aluminum sulfide?
16. When copper (1) sulfide is partially roasted in air (reaction with 02), copper(1) sulfite is
formed first. Subsequently, upon heating, the copper sulfite thermally decomposes to
copper (1) oxide and sulfur dioxide. Write balanced chemical reactions for these two
reactions.
17. Write the molecular, complete ionic & net ionic equation for a single replacement
(redox) reaction between zinc and copper (ii)sulfate? Identify the oxidized and the
reduced species.
18. How many grams of Mg(OH)2 will be needed to neutralize 25 ml of stomach acid if
stomach acid is 0.10M HCI?

2.0 M KOH?
20. Name two safety precautions that you must follow before starting an experiment? (b)
