Introduction

Graphical Analysis is a straightforward program that enables the user to graph, analyze and find the relationship of variables easily (Guerrero 55). Data of the variables is entered from the computer keyboard, extracted from a disk saved file, or pasted from a clipboard. Graphical Analysis is as well a document creator, with the ability to compile different pages to a single document. In an experiment that involves analyzing the relationship between the density and mass of a substance, Graphical Analysis does it very well. The equation y=kx where y denotes the dependent variable, x denotes the independent variable, and ...

Question: what is the appropriate method of identifying compounds as either ionic or covalent based?

Background/Hypothesis Ionic compounds are created from the strong electrostatic bonding between ions (Brinker, and George 393). The covalent compounds have are formed by bonds that result from sharing of electrons (Mah 31).

Solubility test Conductivity test Melting point test Color and odor test Oxidation with oxygen test Steps/Procedures. Solubility test 0.25 grams of the chemical was placed in a test tube. 1 mL of water was added and stirred using a stirring rod. The addition of I mL was added until the chemical dissolved. The chemical that did not dissolve after adding 10 mL of water was recorded. The ...

An acid is a solution that loses hydrogen ions. Common household acids include vinegar and citrus fruit juice. In contrast, a base is a solution that gains hydrogen ions. Acidic substances often taste sour whereas bases taste bitter and feel slippery. Since the tasting or touching of acids and bases can be harmful to human health, Occupational Safety and Health Administration (OSHA, 2013) recommends the use of indicators to test for the acidity or alkalinity of substances. Typically, indicators such as litmus paper change color when exposed to acids or bases (Stanley et al., 2015). As such, the present ...

Introduction

Water is termed the ‘universal solvent’ since it is capable of dissolving a large variety of substances. These solutes can be broadly classified as ionic and molecular solutes, based on their behaviour in solution. Ionic solutes dissociate into their constituent ions when dissolved in water. An example of this class is sodium chloride (common salt). Molecular solutes are dissolved as uncharged molecules, like sucrose (sugar). The effect of ionic solutes on the boiling point of water is the focus of this project. Boiling occurs when the vapour pressure above a liquid equals the pressure over it. Hence, the normal ...

Report for Voltaic Cell Project (Lemon)

The purpose of the experiment is to demonstrate the production of electricity through the use of Zinc, Copper and Lemon. The experiment explores the electrochemical reactions that take place between the two metals in the presence of citric acid provided by the lemon to generate electricity. It highlights the oxidation and reduction reactions that occur within the lemon battery before electrons are released to generate electricity.

Background

The electrochemical reaction that occurs to generate electricity from chemical energy takes place between tow metal pieces, known as the electrodes, and a liquid known as the electrolyte. It is imperative that the ...

Part One

The main purpose of the article is “to assess the concept of grade inflation in higher education institutions in an effort to determine its prevalence, causes, and strategies that can be implemented to curtail it” (Tucker & Courts, 2010, p. 45). The researchers used “A literature review of the problem, as well as several strategies, are presented as possible solutions to restraining the problem of escalating grades in the college classroom” to achieve their objective (Tucker & Courts, 2010, p. 45). The authors established that “The problem of grade inflation has been a topic of concern for over a century and ...

1. a. The pKa value of an amino acid is an indication of how strong or weak an amino acid is, based on the said acid’s dissociation constant. An amino acid that has a high pKa value is weaker than on that has a low pka value. Given that an acid’s dissociation constant is Ka, the pKa value is given by the formula: pKa = -log10Ka pH = pKa + log ([A-]/[HA]),It follows that for Cys12, 7.4= 7.2 + log([Cys-]/[HCys]) 7.4-7.2 = log([Cys-]/[HCys]) 0.2 = log([Cys-]/[HCys]) 100.2= Cys-/HCys Therefore, Cys-/HCys = 10-4Similarly, ...

Procedure 1: Locating the position of a gene

In Ensembl: Search the internet link to the ensemble website: http://www.ensembl.org/index.html On the Genome Browser located on the web page, select the human genome – GRCh38.p5 – to obtain various sub-topics about the genome. Type the name of the gene in the search box of the human genome webpage. The MSRA homepage will contain a summarized description of the gene, including the including the location of the chromosome, its size, and the start and finish nucleotide.

In NCBI:

Search the link http://www.ncbi.nlm.nih.gov/ to obtain the NCBI homepage. Type the gene name MSRA on the gene search box. From the list of search results, ...
