CHEM 120 Week 8 Final Exam A+ GRADED 6. (TCO 6) A gas at a temperature of 95 degrees C occupies a volume of 165 mL. Assuming constant pressure, determine the volume at 25 degrees C. Show your work. (Points : 5) Using Charles’ Law, (V1/T1) = (V2/T2). First, convert temperature to KELVIN (T1 = t1 +273) Thus, T1 = 95 + 273 = 368. We have V1 (165 mL) & T2 = (25 + 273) = 298. V2 = (V1*T2)/T1 = (165 mL*298)/368 = 133.6 mL. 7. (TCO 6) A sample of helium gas occupies 1021 mL at 719 mmHg. Fo...

CHEM-120 Week # 2 DQ 2 – Chemical Structures The electron configuration of an atom determines the number of electrons available to participate in bonding with another atom. One method of depicting the valence electrons that an atom has is through the Lewis structure. To begin this discussion, pick an element from the periodic table of elements. Identify the valence electrons and the orbitals in which they reside. You can use the textbook and lecture. Pick a peers post and answer each of ...

Chem. 120: week 4 Question 1: (TCO 6) A sample of helium gas occupies 520 mL at 79 mmHg. For a gas sample at constant temperature, determine the volume of helium at 45 mmHg. Student Answer: Boyles Law P1V1=P2V2 Temp is constant 79 mmHg x 520 mL= 45 mmHg x V2 41080= 45 mmHg x V2 912.88 mL=V2 Instructor Explanation: Chapter 6; Using Boyle’s law, P1V1 = P2V2. We have V1 (520 mL), P1 (79 mmHg) and P2 (45 mmHg). We want to determine V2, so V2 = (P1 x V1)/P2 = (520 mL * 79 ...
