Lab Report Ionic and Covalent Bonds Lab: Ionic and Covalent Bonds Introduction: The purpose of this experiment was to explore the properties of chemical substances that can be used to identify the types of bonds in a chemical substance using a laboratory procedure. The two types of bonds being identified were ionic and covalent. Based on a substance’s properties‚ how can you determine whether its bonds are ionic or covalent? This is the question I posed before starting the experiment.

Ionic Reactions Abstract This experiment is designed to study the nature of ionic reactions‚ and write net ionic equations for precipitation reactions‚ as well as to identify spectator ions‚ perception reactions and solubility of different compounds. Experiment and Observations In this experiment I was using a 96-well plate to add two drops of the following solutions into seven wells in rows A through E: cobalt (II) nitrate‚ copper (II) nitrate‚ iron (III) nitrate‚ barium

Title of Experiment 12: The Effect of Ionic Strength on the solubility of an Electrolyte Aim: The purpose of this experiment was to determine the thermodynamics variable of enthalpy‚ ∆H for the dissolution reaction of boric acid in water. The solubility of boric acid was measured over a range of various temperatures by finding out at what temperature crystallization began for solution of different molarities. A graphical relationship between the natural logarithm of molal concentration and the inverse

active process which uses ATP energy to transport substances through the membrane. The other method is called passive process which does not require the use of ATP energy. During passive processes‚ molecules are transported through the membrane by differences in concentration or pressure between the inside and outside of the cell. Two important types of passive process are diffusion and filtration. Every cell in the human body uses diffusion as an important transport process through its selectively

Lab Techniques & Measurements Pre Lab Questions: (4pts) 1. What will you learn after completing the lab? -The experiment will introduce different level of precision and measuring to the appropriate decimal place and will be familiar with measurements and weight. 2. Write the symbols and equation used to make a dilute solution from concentrated or stock solution. - The concentration of substance is described as molarity and this can be expressed as – Molarity

Purpose: The purpose of this lab was to analyze the trends of the atomic radius (AR) and the first ionization energy (IE) for the first 36 elements of the periodic table. Procedure: A piece of graph paper was given out by the teacher. A periodic table that has the atomic number‚ atomic radius (AR)‚ and first ionization energy (IE) was given out by the teacher. A sheet of paper was taken out to record the elements‚ atomic number‚ atomic radius (AR)‚ and the first ionization energy (IE). To record

In this essay‚ it will be discussed how the Kinetic Molecular Theory explains many gas law specifically Boyle’s gas law‚ Charles’ gas law‚ and Avogadro’s gas law. To understand what will be talked about is to first know what the Kinetic Molecular Theory is. In our textbook is says it is “A simple model for gases that predicts the behavior of most gases under many conditions.” First off‚ we will take a look at Boyle’s Law. As stated in our lab manual “at constant temperature the pressure which a given

CENTRAL DOGMA OF MOLECULAR BIOLOGY Molecular Biology Laboratory‚ Biological Sciences Department College of Science and computer Sciences‚ De La Salle University-Dasmarinas ABSTRACT: The central dogma of biology holds that genetic information normally flows from DNA to RNA to protein. In the experiment‚ DNA and RNA bead kits were used. Different coloured beads correspond to different nitrogenous bases‚ sugars and phosphates. Different structures of DNA and RNA were formed based on the sequences
