Discussion The purpose of the Density Lab was to determine the identity of four unknown solids and two unknown liquids by calculating their densities and comparing them to a density chart‚ taking into account error analysis and finally classifying the substances. In order to calculate this density‚ we first found the mass of the container that was to be holding the substances. We then found the volume of the substance‚ and lastly determined the mass of the container and substance. We subtracted

Lab Report: Toothpickase and Enzymes September 19‚ 2012 Olivia DePhillips Lab Partner: Joy Morgan Meyers Signature: Introduction Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process‚ called substrates‚ are converted into different molecules‚ called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts‚ enzymes work

AP Biology 6th Mr.Scofield Blast Lab Background: Between 1990–2003‚ scientists working on an international research project known as the Human Genome Project were able to identify and map the 20‚000–25‚000 genes that define a human being. The project also successfully mapped the genomes of other species‚ including the fruit fly‚ mouse‚ and Escherichia coli. The location and complete sequence of the genes in each of these species are available for anyone in the world

Graded Assignment Lab Report Answer the questions below. When you have finished‚ submit this assignment to your teacher by the due date for full credit. 1. (5 points)How would you describe the movement of the sun over 30 minutes? Answer: The movement of the sun will change the angle it has on the sky in 30 minutes‚ it is always moving from the east to the west‚ so in 30 minutes it would move more west‚ no matter at what time you make the experiment. 2. (5 points)You have two sun sticks.

Purpose: The purpose of this lab is to identify the presence of cations and anions in four unknown solutions by identifying whether they are copper‚ silver‚ iron‚ or chloride ions which is done by adding sodium hydroxide‚ solid copper‚ silver nitrate‚ and potassium thiocyanate to the solutions and analyzing the chemical reactions. Introduction: Chemical change‚ unlike physical change is the change in the composition of a substance rather than simply its shape‚ size‚ or state (Marie‚ 2015). Signs
