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

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

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

second lab activity dealt with two-point acuity. Different parts of our body performs a specific function that which they were built to execute. However‚ the sensitivity each surface of our body reveals to be different. Some areas of the body will have a variety of sensory receptors‚ which requires more sensory input. Therefore‚ body parts have their own sensation depth that one can measure through two-point acuity. Results Participant #1: Initially‚ the researcher placed the compass points with

2. A sample of gas is confined to 30ml at a pressure of 6 atmospheres. When the pressure is changed to 3liters‚ what is the resulting pressure? 3. A gas occupies 30 L. When the gas is heated from 50C to 100C‚ what is the final volume? 4. In a lab‚ Neon vapor occupied a volume of 1 liter at STP‚ the volume was changed to 4 liter and the temperature climbed to 25C‚ what was the final pressure? 5. Originally a gas occupied 600ml at 22 C what was the final volume at STP? 6. A sample that contains

BOILING POINTS Introduction: The boiling point of a compound is the temperature at which it changes from a liquid to a gas. This is a physical property often used to identify substances or to check the purity of the compound. It is difficult‚ though‚ to find a boiling point. Usually‚ chemists can only obtain a boiling range of a 2 - 3oC accuracy. This is usually sufficient for most uses of the boiling point. Purpose: The purpose of this experiment is to determine the boiling points of various
