experiment we found that you can calculate the density of elements with close presotion with crude experiments Introduction The aim of this experiment was to see how close you could measure the density of atoms with crude experiments. The second part of the experiment dealt with Solubility of large ions and their Hydration enthalpy. Hydration enthalpy is the enthalpy change when 1 mole of an ionic substance dissolves in a solution to give a solution of infinite dilution. (Jim Clark‚ 2010). (Jonathan

Density (Linearized plot) TA: Blue Rex rex Group Members: Billy and Mandy Tuesday; 1200-1350 Abstract: In this lab the density of hand-made clay balls were calculated to understand how scientists model physical effects and to understand logarithmic plots. The hand-made balls ranged from diameters of 2cm to 6cm and were measured with vernier calipers by each member of the group. A total of 6 independent measures of each diameter were taken to establish uncertainty. The clay balls were then

social‚ realist‚ drama "No Sugar" can be considered as a forum to highlight the impacts of the European social and political philosophy of the early 20th century on Aboriginal society. It is a political text that exposes social issues. It expresses these issues using the form of drama and the use of staging conventions to challenge the audience into developing an opinion on the topics. The play was staged on a perambulant model‚ meaning that the action of the play shifts between several locations: There

Nutrition Density Essay After having calculated the nutrient density of seven food groups in a spreadsheet‚ the food group that came to have the highest Nutrient Density was the vegetable group obtaining an average of 7.76712 Nutrient Density. The food group that came to have the lowest Nutrient Density was the “junk food” group‚ having an average of 0.24845 Nutrient Density. One of the factors that contribute to foods having a high or low Nutrient Density is the amount of calories. I noticed that

is a commonly known fact in Australia‚ and throughout the rest of the world‚ that Aborigines were mistreated from since western culture first settled‚ and for many years after that. It is the main purpose of stage dramas to bring issues‚ such as the one mentioned above‚ and ideas about these issues to life through dramatic performances and the use of a number of various techniques. No Sugar‚ a revisionist text written by Jack Davis in 1985‚ is one of these stage dramas. Jack Davis brings issues and

issues underlying No Sugar 1. No Sugar challenges the prejudiced‚ negative stereotypes of Aborigines operating in a mainstream Australian society. Despite the Mullimurras’ problems‚ they survive as a family with resourcefulness and dignity. Discuss this statement in relation to your reading of the play. The 1920s and 30s was a time of deep prejudice against the Aboriginals. They were put through an experiment by the Chief Protector of Aboriginals at that time‚ Mr. Neville who was trying to "breed

No Sugar No Sugar (1986)‚ a play exploring the treatment of Aboriginal people in the 1930’s‚ was written by Jack Davis‚ an Aboriginal Western Australian who grew up in Yarloop and the Moore River Settlement. No Sugar is told from the point of view of an Aboriginal family who are coerced into living at an Aboriginal reserve because the white people in their community didn’t like them living close to them. The authority at the settlement are very abusive creating conflict between the Millimurra family

Experiment #2 “Density Determinations” Report The objective for experiment #2 was “to determine densities of objects/salt solutions with different concentrations of salt‚ to see how density changes as a function of concentration.” In experiment #2‚ part II‚ calculations of Density of NaCL solutions were made from 0%-25% NaCL concentration. My hypothesis was that as the % increased‚ so would the density‚ because adding weight would increase the density of each solution. The density calculations in
