Empirical Evidence 1. gas produced that will relight a glowing splint 2. gas produced that will cause a lit splint to "pop" 3. increase in pH 4. decrease in pH 5. solid metal is produced 6. solid metal reacts 7. blue colour fades 8. blue colour forms As you will learn in Module 6, some redox reactions do not occur spontaneously and must be forced. The equation shown below is one such example. Select all of the empirical evidence that would accompany this reaction as it proceeds.

Consider the products of the following double replacement reactions and determine the correct chemical formula for the compound that will form a precipitate (a solid) in this reaction. If no precipitate is formed type the word NONE in all capital letters. When typing chemical formulas do not use a space between the symbols for the element and or the parenthesis (when used). Do not format the subscripts. (i.e sodium phosphide enter Na3P). If no precipitate is formed type the word NONE in all capital letters. a) Pb(NO3)2 + KI = ? b) Al2(SO4)3 + NaOH = ? c) HCl + KOH = ? d) NaCl + AgNO3 = ?
