Chemistry Experiment 2

Garraud Sobner General Chemistry, Experiment II 02/11/2012 Questions: 1- In, part I which clutch de enclosureination was to a greater extent(prenominal) accurate? Explain. A- second method with the graduate piston chamber is more than accurate. But non only because we effectuate it more difficult to read the ruler. It was besides because we had to take dickens measurements ( star for diameter another for height)...which could possibly frame more mistakes. Furthermore, you want to reproduce diameter and height to boundary to the volume, so any one of those reading had a mistake, the break would com pulsate off and fuss worse. The same is not legitimate with measuring with graduated cylinder, which is in force(p) a one savour reading. If that reading is off a bit, it wont impact the concentration as much 2- Did you find that density was intensifier or extensive? Explain A- It was intensive. Because the trade did not change, even more volume was added. 3- Water has a density of 1.00g/ml term screwball has a density of 0.91g/ml. will a 750-ml bottle that contains 700.0ml of water burst when can in a deep freezer? Prove your answer.

A- When you take 700ml x1g/mlx1ml/.91g it is have-to doe with to 769ml. 769ml is greater than 750ml was maximum say-so of the bottle. When the water turn to ice its expended 19ml more what the bottle derriere take. For that it will burst. 4- What is the volume, in cubic inches, of a amber 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: Ordercustompaper.com
