results were compared to the data of the first bead set to look for any systematic errors that may have occurred. During the experiment‚ the data was used to see whether the diameter‚ mass‚ and density were constant between the individual beads. However‚ the main goal of the experiment was to answer the question of whether or not individual density average agreed with the bulk density. Analysis Through error analysis‚ the data found was used to determine if the calculated densities were the

modern society our perspectives on issues have altered. Out of the many of the push factors that Ireland was faced with the “Great Potato Famine” was the basis for many people immigrating. Many other reasons that the Irish had begun to immigrate were from political reasons‚ rising poverty levels‚ and spread of disease. The famine during 1847- 1852‚ lead to the potato harvest to fail year after year. This resulted in the increase of food cost‚ forcing the middle class to become poor. This issue had

thing in automotive fuel may very well be hydrogen. Automakers rapidly are closing in on making hydrogen fuel cell vehicles an everyday fact of life‚ with several test models set to debut over the next few years. Hydrogen fuel cells to power vehicles are desirable‚ experts say‚ because hydrogen is a renewable fuel that can be used to create electricity to run cars. A chemical reaction between oxygen and hydrogen produces the electric power‚ and when pure hydrogen is used‚ the only emission from the tailpipe

remained in power by taking away the Irish people’s land and reallocating it to Scottish farmers. The United Kingdom of Great Britain and Ireland was formed in 1801. The Irish people were upset by this and did not want to lose their independence. The Potato Famine that lasted from 1845 to 1848 took its toll on the population of Ireland‚ which went from 9 million to 3 million. The famine oppressed the undernourished people‚ yet Britain failed to offer sufficient support. Gladstone became the Prime Minister

Ireland suffered greatly during the potato famine in the 1840s. Around one million people died of starvation or disease. Many immigrated to the United States to try to escape the horrid that surrounded them in Ireland.Food was considered the most deadly weapon in a war. Starvation was the leading cause of death in a war. If you had control of the food supply‚ your army had the greater advantage. Your enemies would most likely fall from starvation‚ enviably you would win. Food also gave the soldiers

Chemistry Write-Up The Thermal Decomposition of Sodium Hydrogen Carbonate Aim: When Sodium Hydrogen Carbonate (NaHCO3) is heated‚ Carbon dioxide and water are given off to leave a white powder. The aim is to find the equations for this reaction. Hypothesis: The experiment will prove which of the equations below is true. It will tell us whether Sodium Carbonate is produced or Sodium Oxide. 2NaHCO3 Na2CO3 + CO2 + H2O 2NaHCO3 Na2O + 2CO2 + H2O Variables: Independent: Original

effect of salt concentration on osmosis in potato. Introduction: 1. The purpose of doing this lab is to observe the effects of various solute concentrations on osmosis in a potato. 2. During osmosis‚ water moves from the side of the membrane where they are most concentrated to the side where they are less concentrated. If the concentration is equal on both sides‚ there will be no movement. 3. I hypothesize that the mass of the potato will decrease as the salt in the solution
