Yes, #1 is right. To do #2, look at your equation and fill in the blanks but I will use symbols to save space.
Cl2 + 2KBr ==> 2KCl + Br2
4.0...13.4.....8.4.....x
Remember the Law of conservation of mass; i.e., matter is not created or destroyed. Therefore, since you have 17.4 g on the left you must have 17.4 g on the right. You know KCl is 8.4 and remainder must be Br2.
12.) Chlorine reacts with potassium bromide to produce potassium chloride and bromine.
a.) write a chemical equation, using words, to represent the above chemical reaction.
Answer: Chlorine + potassium bromide ==> potassium chloride + bromine
(Is this correct?)
b) Suppose 4.0 g of chlorine completely reacts with 13.4 g of potassium bromide producing 8.4 g of potassium chloride. What mass of bromide is produced?
