of ethanoic acid and sodium hydrogen carbonate Cristina Li 17th April 2017 Introduction The hypothesis is the balloon will be bigger and bigger with the increase of vinegar. The chemical reaction between the baking soda and vinegar produces bubbles of carbon dioxide gas as part of this acid-base reaction. Sodium hydrogen carbonate (baking soda) reacts with ethanoic

was that the balloon would always follow the boy around‚ even though many people tried to stop it/him. The balloon would always find a way to be with the boy. But it was broken at the end‚ when the balloon was hit‚ and the cycle ended. Many of the other generalizations would not have worked. “The end of a cycle cause the cycles to begin again; a cycle may appear to have no beginning or end.” That does not work‚ because as it showed in the film‚ the cycle did have an end. The balloon died. The cycle

If I take the balloon with me to Denver‚ where the air pressure is 0.85 atm‚ what will the new volume of the balloon be? P1V1 = P2V2 (1.0 atm)(15 L) = (0.85 atm)(x) x = 18 L 3) I’ve got a car with an internal volume of 12‚000 L. If I drive my car into the river and it implodes

The following materials were used in the completion of this laboratory experiment: * Meter stick * Two paper towel rolls / cardboard tubes * Scissors * Two rubber bands * Wax paper * Transparent tape * Flashlight * Balloon Procedure Part 1: 1. Hold one end of a meter stick down on a tabletop so that 20 cm of the stick extends past the edge of the table. 2. Pluck the end of the stick that is extending past the edge of the table to produce a vibration and

Roadside Memorials The issue is roadside memorials and whether they should be allowed on the side of the road or not. There is a large controversy over roadside memorials because some people believe they are distracting and should be illegal altogether because they have caused car accidents that result in more deaths. Others believe that people deserve the right to express their grief in any form. This issue had become problematic because the amount of roadside memorials in increasing. Roadside

important in determining the answer to this question. One is how much kinetic energy is needed to push the water bottle car forward. Also‚ Newton’s third law of motion tells how the air can push the car forward based on the force that the air from the balloon pushes backwards. Aerodynamics helps clarify how the air moves over the car and reduces the drag of the car. Overall‚ all of these factors play a part in determining which water bottle-designed car travels the fastest. The definition of energy is
