Brian Toohey Biology Mrs. Heimforth 12/06/10 Diffuse the Osmosis Section 2: Introduction Step 1: The scientific concept of this lab was to see how osmosis transferred the substance through the cells to reach equilibrium. Step 2: My hypothesis was that the bag with 60% sucrose then it would be heavier than the bag with tap water or 30% sucrose. I thought this because I thought that there would be more of a substance change in 60% sucrose. Section 3: Methods First get 3 pieces of the same

of this experiment was to investigate the relationship between mass‚ frequency‚ bond strength. Using the Infrared Spectroscopy‚computer simulations‚ and spring stiffness provided with evidence that validated the experiment. The first set of test focused on how the mass of certain molecules affect vibrational frequency. Table A1. shows two different masses with two different frequency. A spring stiffness of 85 g/cm was used with a mass of 430.31g showing a frequency of 60(s/1) . Using the same spring

performed and the power developed when climbing a set of stairs and to determine the relationship between power and time. Pre-Lab Questions: 1. Power is the rate at which work is done. The work divided by the time it takes for the work to be done equals power. 2. The unit for power is the Watt which is Joules/second. 3. One horsepower (hp) is 746 watts. Procedure: In this lab‚ we calculated the work performed and the power that person creates when he or she climbs and runs a set of stairs. Each

You need a very quick chemical reaction‚ a large and quick change or increase in gas pressure‚ and a container‚ or a vessel that holds the pressurized gas to the point where it can violently break out of its container. In this experiment‚ the gas being pressurized is ethanol. The equation C2H6O+3O2→3H20+2CO2+heat states that ethanol combines with the other parts of the equation in order to make enough energy to cause

When talking about the most efficient air bag we are talking about using the least amount of chemicals to make the most carbon dioxide to inflate the bag. We hypothesized that a small amount of sodium bicarbonate with a small amount of acetic acid will create enough carbon dioxide to inflate the bag so Humpty
