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 OL Lab 11: Carbohydrates: The sugars that feed us Learning objectives • Explain the molecular structure of sugars and polysaccharides • Explain digestion and appreciate the complexity of the human body • Experiment with different foods and measure their impact on the blood sugar level Introduction Most people are familiar with carbohydrates, especially when it comes to what we eat. For example, to lose weight, some individuals adhere to “low-carb” diets. Athletes, in cont...
