CHEM 103 Lab Exam 5 – Portage Learning. In the Boyle’s law experiment, how was the volume of gas at different pressures determined? 2. (2 points) According to Boyle’s law, as the volume of a gas decreases, the pressure _________. 3. (6 points) A sample of gas occupies a volume of 10.5 L when the pressure is 14.3 psi. Use Boyle’s Law to calculate the volume (L) when the pressure is decreased to 12.8psi. Show the calculation. Answer: 1. A syringe was used, and the volume was read f...

CHEM 103 Notebook entry for lab 7 _Molality Colligative properties (Portage Learning) MOLALITY COLLIGATIVE PROPERTIES Experiment #7 - Molality Colligative Properties Date: 06-18-2020 Title: Molality Colligative Properties Purpose: - The purpose of this experiment is to demonstrate the idea of colligative properties. We will demonstrate this by making something most people love, ice cream. Procedure: To do this we need to use (NaCl and CaCl2). ● We will measure the amount of salt...

AAMC FL 2 Chem/Phys correctly answered 2023What atom is the site of covalent attachment of AMC to the model tetrapeptide used in the studies? A. I B. II C. III D. IV - correct answer A. I basically asking where does the bond between amc and Y break. since you know they are attached by a peptide bond, which means the peptide chain attaches to the amino group of the next amino acid( that's why an amino acid runs from the N-terminal to the C-terminal), the covalent attachment is at site 1 ...
