Physics 30 Lesson 38. 1) In the early 1900 s electrons, protons and neutrons were thought to be fundamental. Since that time, protons and neutrons are now thought to be made of quarks. The electron remains as a fundamental particle.
1. SULFURIC, SULFUROUS, AND METHANESULFONIC ACIDS. Each split was weighed out in a glass bottle of known weight. Bottles were partly filled with water and acid was added with an Eppendorf pipet to a concentration of 10 g/L for sulfuric and sulfurous acids.
Lab: Alka Seltzer Time Bombs. Prelab Questions. Describe how the rate of a reaction can be measured. What can be changed with regards to temperature, concentration and surface area to increase the rate of a reaction? What will you observe in the lab? What conditions will be varied in the lab?
Chemistry: Atomic Structure. Organization of the Modern Periodic Table. The periodic table is organized by properties. An element is where it is on the Table because of its structure and, therefore, its properties. Regions of the Periodic Table. There are three main regions of the periodic table.
