Coulomb’s Law Purpose: The purpose of this lab was to demonstrate that the force between two stationary charges is directly proportional to the product of the charges and inversely to the square of the distance between them. Coulomb’s law tells us that the force between two charges depends (1) linearly on the strength of each charge‚ and (2) inversely on the square of the distance between them. Mathematically we would write this as . Procedures Part1 Begin by removing the right side

Introduction The purpose of this lab was to recognize the stages as well as events of mitosis and meiosis in a plant cell or an animal cell. The relative duration of each stage in the cell cycle will also be learned during this lab. By doing this lab we will also create a model of and understand the process of crossing over. This lab also helps students understand the similarities along with differences between mitosis and meiosis. Purpose The objectives of the lab were to help give us a better

The Mass of Acetylsalicylic Acid in Aspirin ------------------------------------------------- Purpose The purpose of the lab is to determine the mass of the ‘active ingredient’ in a commercial ASA tablet. ------------------------------------------------- ------------------------------------------------- Introduction There are three main theories surrounding acids and bases including the Arrhenius‚ Bronsted-Lowry‚ and Lewis theories. The Arrhenius theory of acids and bases states that

Lab Report 1 Introduction: Proper chemical formulas entitle many challenges such as the Law of Multiple proportions that states that there may be more than one plausible mole ratio for the elements in that compound. However if we determine the mass of each element in the compound we will be able to get the true chemical formula. In this experiment‚ we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper‚ chlorine‚ and water molecules

Determine the % change in mass over the week and report these in a chart and graph. Be sure your graph has all of the appropriate titles and units. Analysis Questions: 1. For this experiment‚ what were the independent variable and the dependent variable? What was the control? What were some constants in this lab? 2. Calculate the average rate of water loss per day for each of the treatments. (Humidity‚ Light‚ Fan‚ Dark‚ Room or control). 3. Explain why each of the conditions

Popcorn Lab Report Background: Chemistry is the study of matter‚ its properties and the ability to change. This can be used to describe the process of popcorn and the change it undergoes to turn into the movie theater snack we know. The United States supplies most of the worldwide supply of popcorn available today‚ although the popcorn has to meet specific industry standards which can be tedious to do for the 50 million pounds of output per so sampling has to be used. Sampling is known as

Collision Lab Simulation Purpose: To study elastic and inelastic collisions in one-dimension. Background Information: Momentum: is a measure of mass in motion. It is the product of mass x velocity. Conservation of Momentum: in the absence of external forces‚ such as friction‚ the linear momentum of a system remains constant. Procedure: 1. Open web browser and go to the site: http://phet.colorado.edu 2. Click “play with sims”‚ then “physics”‚ and then “motion” 3. Find the “Collision Lab” 4
