Question

Make Lewis structures; predict the molecular geometry and polarity of the following molecules: (16 Points) NCl2, BF3, SeO2, CH4, CHCl3, NH3, NO2 Do the following unit conversions: (16 points) 1 inch = 2.54 cm, 1 lb = 454 g 25 cm = ? inches 2.54 m = ? inches 25 m = ? cm 122 K = ? Â°C 2.2 lb = ? kg 3.2 liters = ? cm^3 12.2 mg = ? g 58.350 K = ? Â°F In a lab experiment, KI was synthesized by the decomposition of KIO3. How many grams of KI will be produced by 0.1662 moles of KIO3? Find the percent yield if the actual yield of KI was 0.1125 grams. In a titration experiment, 17.5 mL of 0.15 M NaOH solution was needed to reach the end point with 25.0 mL of HCl solution. Find the molarity of the HCl solution. Find the pH of the solution if: a) [H+] = 0.000025 M b) [OH-] = 0.000025 M c) pOH = 3.21

Do the following unit conversions: (16 points) 
1 inch = 2.54 cm, 1 lb = 454 g
25 cm = ? inches
2.54 m = ? inches
25 m = ? cm
122 K = ? Â°C
2.2 lb = ? kg
3.2 liters = ? cm^3
12.2 mg = ? g
58.350 K = ? Â°F
