Chemistry Experiment 2

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 grade cylinder is more accurate. But not only because we assemble it more difficult to read the ruler. It was also because we had to take heller measurements (one for diameter another for height)...which could possibly create more mistakes. Furthermore, you require to multiply diameter and height to line to the volume, so whatever one of those reading had a mistake, the error would com pound glum and get worse. The same is not true with measuring with gradational cylinder, which is in force(p) a one shot reading. If that reading is move out a bit, it wont impact the niggardliness as much 2- Did you watch over that density was intensive or extensive? Explain A- It was intensive. Because the hole did not change, even more volume was added. 3- Water has a densi ty of 1.00g/ml term glass has a density of 0.91g/ml. will a 750-ml bottleful that contains 700.0ml of water burst when jell in a deep-freeze? Prove your answer.

A- When you take 700ml x1g/mlx1ml/.91g it is disturb 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 boxy inches, of a grand 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= 7.3cub! ic 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
