Meiosis and Genetic Diversity lab BIO LAB 028 Introduction In this lab the spores of the Sordaria fimicola, a fungus, is examined after meiosis and mitosis. During meiosis, there is always crossing over of genes between the chromosomes, allowing for genetic variation. The eight ascospores contained within an ascus are examined under a microscope and their order determined. The determination of their pattern depends on whether or not there was crossing over – if there was, they are in a 2:2:2:2…
Ionic Compound combined with reactant to make a white substance. The reason for this lab was to find out which of the seven unknown chemicals were combined with a reactant to make a solid white substance. If two combinations of ionic compounds are mixed then it will create a white substance. By using the ionic compound lab it identifies the compounds and then combined to find the result of the solid white substance. The effects of water contamination of calcium, chloride, iron and copper ions on…
In some places around the world that I’ve been to, I notice children drinking water that is foggy looking. If you see water that’s foggy, I don’t think you’d drink it either. In the labs we did, we tested to see which substances was the unknown, and we also tested for pH levels. These labs can help test whether the liquid is safe to drink. In the Revisiting Zinc/Iodine Lab, we took 2 grams of zinc and 2 grams of iodine and mixed them together in 10 mL of water in a flask. We weighed the contents of the flask then swirled the flask…
potential to mix with stomach acid and undergo a chemical reaction. In a lab, sodium benzoate can be combined with hydrochloric acid (HCl) to simulate the stomach environment. The purpose of this experiment is to determine when these two substances are combined, whether a new substance will be formed. It was predicted that a new substance would form from the combination of sodium benzoate and HCl because when combined, a reaction takes place where protons will transfer from the acid (HCl) to…
CHEMISTRY 361 Analytical Instrumentation Syllabus Spring 2012 Professor: Dr. Evans E-mail: jason.evans@umb.edu Telephone: 617-287-6149 Office hours: TH 8:30-10 or by appointment Office: Science 1-084 Lecture/Lab: M 11:00-11:50 and F 12:00-5:00 in S-2-41 Objective: This course provides a survey of the different types of instrumentation that is in the chemist’s tool box. We will stress advantages and disadvantages and develop the insight that is necessary to choose the right tool for the…
Abstract This lab is performed in order to determine the total energy in a reaction between zinc and hydrochloric acid. The reaction is done twice, once to measure the heat of the reaction and again to determine the work done in the system. This is because Enthalpy equals heat plus work (∆H= ∆E+W). Heat and work can be broken down further into separate components so the equation used in lab is ∆H=mc∆T + PV. Many calculations are used in the lab to find out what cannot be measured directly (ex:…
Forry/Stanton 1 Mckenna Forry & Megan Stanton October 26, 2014 Honors Chemistry/ Pd. 8/ Mrs. Gazzara Chemical Reaction Lab Objective:to examine the chemical properties of hydrochloric acid and copper chloride, to identify the types of reactions that they undergo and to determine if the law of conservation of mass applies to a sample chemical reaction in one of these series. Materials: ● Aluminum shot ● ammonium hydroxide solution ● cupric chloride solution ● hydrochloric acid solution…
purpose of the lab was to find evidence that a chemical reaction had been formed by mixing different chemicals. Signs of a chemical reaction are gases being produced, color change, precipitates formed, or temperature change. Materials used were varieties of liquids, solids and lab equipment. The procedures included observing the solids or liquids before mixing or heating them, how much of each substance should be used, rinse the test tubes after each observation, and finally clean the lab stations after…
coating around it Treated with Zn+ NaOH & heated in the flame Mostly gold with a little brown; extremely shiny Discussion of Theory: In the Striking it Rich Lab we used our knowledge in class to manipulate the properties of different pennies. First, we had to mix Sodium Hydroxide (NaOH) in with water. In order for our lab to run more efficiently, we affected the rate of the dissolution of the NaOH by agitating the solution to increase the number of the collisions between particles. Next…
