Chemistry Experiment 2

Garraud Sobner General Chemistry, Experiment II 02/11/2012 Questions: 1- In, part I which spile de shapeination was to a greater extent(prenominal)(prenominal) accurate? Explain. A- second method with the graduate piston chamber is more accurate. But non only because we effectuate it more difficult to read the ruler. It was also because we had to take dickens measurements ( star for diameter another for height)...which could possibly make believe more mistakes. Furthermore, you want to spawn diameter and height to fund to the volume, so any one of those reading had a mistake, the mistake would com stupefy off and contribute worse. The same is not neat with measuring with graduated cylinder, which is in force(p) a one surmise reading. If that reading is off a bit, it wont impact the niggardliness as much 2- Did you find that density was intensifier or extensive? Explain A- It was intensive. Because the hoi polloi did not change, even more volume was added. 3- Water has a density of 1.00g/ml term churl has a density of 0.91g/ml. will a 750-ml bottle that contains 700.0ml of water burst when assign in a deep-freeze? Prove your answer.

A- When you take 700ml x1g/mlx1ml/.91g it is adjoin to 769ml. 769ml is greater than 750ml was maximum strength of the bottle. When the water turn to ice its expended 19ml more what the bottle lav take. For that it will burst. 4- What is the volume, in cubelike inches, of a money nugget that has a mass of 82.00 ounces? Density of Au=19.3g/cm3; 453.6g=1pound; 16 ounces=1 pound; 16.4cm3=in3 A- 82 ounces is one gold nugget. (82/16) x453.6 =2324.7grams; (2324.7g/19.3)/16.4= 7.3cubic inches 5- A- D=m/V ; 7.3x16.4x2.70=323.24gramsIf you want to get a full essay, order it on our website: Orderessay
