Type the correct answer in each box. In an atom, the first energy level can hold electrons. The second energy level can hold electrons. The third energy level can hold electrons.

Given the following chemical equation, if 162.0 grams of potassium reacts with excess oxygen gas and was found to produce 172 grams of potassium oxide, what is the percent yield for this reaction?4 K (s) + O2 (g) - - > 2K2O (s) 44% 75% 22% 88%

3. Using Equation 18-5 and the pKIn value you found, determine the ratio [In-]/[HIn] at the pH in the middle of the range you studied (i. e., pH = 6.0 for bromocresol purple, pH = 7.0 for bromothymol blue, and pH = 7.7 for phenol red).
