CHEM-120 Unit 4 Lab: OL Lab 8: Acids and Bases CHEM120 OL, Week 4 Lab Observations: Record three observations from the simulation. The temperature scale is arbitrary. Change in gas physical pro perty is linked to temperature change. Ideal Gas law states that volume is proportional to temperature. Answer the questions below: 1. If the pressure of a fixed volume of gas decreased in a sealed container, what variable would you think changed? Did this variable increase or decrease? Pressure of gas is...

CHEM 120 Prelab week 1 PRE-LAB Prelab: Using the Scientific Method 1 point for each complete answer, 5 points total. This exercise is due at the start of lab. Your instructor will initial here to indicate on time completion. You will then turn this exercise in with your completed lab. Atoms and molecules spontaneously flow from areas of high concentration to areas of low concentration in a process known as diffusion. The rate of diffusion is affected by many factors including the molar mass o...
