distillation that can be used. In this lab‚ simple and fractional distillation was used. The simple distiller is composed of a 100ml round bottom flask that is attached to: a 3-way adapter‚ thermometer‚ condenser and vacuum adapter. The apparatus is heated up by placing a powermeter at the bottom of the 100ml round flask. When the temperature becomes high enough to effect the boiling point of one of the compounds in the solution‚ vapor is created. The gas then travels down the condenser where

1- That would be inelastic. Even though people gripe about the rising prices‚ that doesn’t stop people from stopping by the gas pumps to fill up.Elastic is more like candy bars or soda; if priced at 50 cents‚ there will be high demand‚ but if the price rises to 2 dollars‚ the demand will go down.Because there are many alternative brands for Coca Cola that have more or less the same taste. When the price of coca cola rises‚ demand decreases because consumers will find alternative brands that taste

Kiley O’Toole Lab Report 3 Purpose The purpose of this lab was to uncover the number of layers of zinc atoms around a piece of galvanized iron. This was done by pouring the hydrochloric acid onto the galvanized iron‚ thus removing the zinc from the piece of metal. Laboratory Procedure 1. Measured and recorded the mass of a piece of galvanized iron using a centigram balance and a ruler 2. Measured and recorded the length and width of the galvanized iron using the ruler 3. Put the

solution. 3. Using the formula molar mass = grams/moles calculate the molecular mass of antifreeze in the 10% solution. 4. Using the equation ΔT = Kf m¸calculate the molality of the 20% antifreeze solution. 5. Use the formula molality = moles solute/kg solvent to find the number of moles in 20% antifreeze solution. 6. Using the formula molar mass = grams/moles calculate the molecular mass of antifreeze in the 20% solution. 7. Average the molar masses you calculated in questions

Chapter 2: Try as You Might‚ You Can Never Escape from Hiratsuka Shizuka 2-1 The cicadas were noisy right from the crack of dawn. According to the TV I had left on in the background‚ today was going to be summer’s biggest heat wave yet or something. Didn’t those guys say that every day? This was like those super talented idols the likes of which are only seen once every decade‚ and yet‚ for some reason‚ pop up every year. The heat was making me grouchy‚ so I switched off the TV abruptly. Then I collapsed

Biology 20 IB Design Lab Does increasing or decreasing the ph level of a 3% concentration H2O2 (l) solution affect the amount of oxygen released between 15.0ml of the solution and a 5g sample of liver? The reaction is measured by the difference in mass of a balloon that is used to capture the amount of gas released by the catalase enzyme found in liver reacting with a basified 3% H2O2 (l) and an acidified 3% H2O2 (l) . Chemical reactions occur when two or more molecules interact and the molecules
