Garraud Sobner General Chemistry, Experiment II 02/11/2012 Questions: 1- In, part I which flock determination was more(prenominal) accurate? Explain. A- 2nd method with the potassium alum cylinder is more accurate. But not only because we erect it more difficult to read the ruler. It was also because we had to take the Tempter measurements (one for diameter another for height)...which could possibly create more mistakes. Furthermore, you deficiency to multiply diameter and height to line to the volume, so either one of those reading had a mistake, the error would com pound pip and get worse. The same is not true with measuring with have cylinder, which is in force(p) a one shot reading. If that reading is discharge a bit, it wont impact the constriction as much 2- Did you look that density was intensive or extensive? Explain A- It was intensive. Because the agglomerate did not change, even more volume was added. 3- Water has a density of 1.00g/ml term chalk has a density of 0.91g/ml. will a 750-ml bottleful that contains 700.0ml of water burst when quad in a deep-freeze? Prove your answer.

A- When you take 700ml x1g/mlx1ml/.91g it is concern to 769ml. 769ml is greater than 750ml was maximum potentiality of the bottle. When the water turn to ice its expended 19ml more what the bottle tin take. For that it will burst. 4- What is the volume, in cuboid inches, of a flamboyant 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 =2324.7g rams; (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: BestEssayCheap.com
