CHEM 120 Week 1 Concepts; Atomic Structure

CHEM120 Week 6 Concepts: Nuclear Chemistry, Energy, and Biochemistry- Download To Score An A+ LAWS OF THERMODYNAMICS In this section, we explore the rules of energy that we observe in the universe . We see many examples of these laws in action on a day-to- day basis. You will learn how to compare and contrast exothermic and endothermic reactions as well as the first and second laws of thermodynamics. 1. Which of these would you classify as an exothermic process? o Evaporation of alcohol o Photos...

CHEM120 Week 2 Discussion: Atomic Structure – Ibuprofen (Option 1) Initial Post Instructions Option 1: Your initial post in the discussion this week consists of two parts. First, choose a molec ule used in healthcare, industry, or found in a natural source and discuss the importance of this molecule. Be sure to include at least one outside source and make sure to follow APA citation guidelines. In the second part of your initial post, we will be practicing naming ionic and covalent compounds a...

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. 0 7 Short 16 7. (TCO 6) A sample of helium gas occupies 1021 mL at 719 mmHg. For a gas sample at constant tempera...
