The Color of Water

various environmental extremes. Procedure: Filled each test tube with substances provided and subjected them to various conditions. These conditions included, heat, cold water, hot water, acid and basic additions and tested on litmus paper. The reactions were observed and documented at each step. Data tables: Substance name Color Odor Effect of heat Cold H2O Hot H2O Litmus Test Dilute HCl Dilute NaOH Mg Small silver, metallic, shards No smell Shriveled up and turned white. Produced gas

researchers from a local lab are trying to get funding for a research study to determine if the color blue is better than the color green. They have written a proposal and submitted to the company that could potentially give them the money needed to conduct the study. The researchers proposed to carry out their study in four different geographic locations and use variations of both the color blue and the color green to ensure that they will gather reliable information. Should the company give the researchers

Visible light is all the colors that we can see. Ultraviolet light can help things grow but to much can cause diseases such as skin cancer. X-rays are used as a tool to find broken bones or take pitchers of our sun. Gamma rays are used in medical science but they are often used to produce images of our universe. If you would like to know more about the spectrum keep reading. The electromagnetic spectrum is the organization

one turned green and completely changed. The experiments started with two cups. One was labeled water, while the other one was labeled vinegar. In each cup, paper towels were placed at the bottom. In the cup labeled vinegar, vinegar was added and in the cup labeled water, water was added. Then, one penny was placed in each cup and observed on a span of four days. On the first day, penny A (cup with water) looked the same. Penny B (cup with vinegar) had a strong smell and the penny looked shinier. Later

One of the most highly regarded painters of the nineteenth century is Winslow Homer. From his birth in Boston, Massachusetts, he began learning about art. Homer’s mother was a water color artist and taught him a lot of the techniques he used in his works. The “Snap the Whip” painting is probably Homer’s most famous painting and exemplifies the ideals he tried to get across. All in all, Homer was one of the most influential painters in American history. Winslow Homer was born in Boston, Massachusetts

Evolution of gas—When a gas is formed it is evidence that a chemical reaction has occurred. In this reaction HCl(aq) and solid NaHCO3 were converted to NaCl, water, and CO2(g). We can see the bubbles in the aqueous solution. (-- removed HTML --) NaHCO3(s)+HCl(aq)→NaCl(aq)+H2O(l)+CO2(g) Temperature change—The burning of methane produces heat and that is evidence that a chemical reaction has occurred. When bonds are formed, energy can be released. We are actually feeling the formation of new

oxygen is not 1:2:1. Instead, lipids have a much higher number of carbons and hydrogens with few oxygen atoms present. The nonpolar bonds that form between the carbon and hydrogen atoms of a lipid cause them to be hydrophobic, or water-repellent, molecules. This explains why water and oil do not mix. The large number of carbon to hydrogen bonds also serves to make lipids energy rich storage molecules. One gram of lipid stores

Teja Chilukuri English 3IB, Period 1 10-16-14 IB English 3 Individual Oral Presentation The Great Gatsby: Inverted Archetypes Statement of Intent: In this presentation, I intend to explain the use of inverted archetypes in The Great Gatsby, by F. Scott Fitzgerald. What is the author trying to establish by using recurring symbols or motif? How does the use of inverted archetypes throughout the novel help advance the plot, and gain a deeper meaning to what is happening in Gatsby’s life? I. Intro

change. A physical change occurs when a substance undergoes a change in form or physical properties without a chemical reaction or the creation of a new substance. For example, when water is heated, it creates steam. The steam is still water, but it is in a gaseous state. In the salon, when we apply temporary color to the hair, we are creating a physical change
