Chemical Rocket Reaction Rocket

What is the appearance of reactant, Evidence of chemical reaction, and properties of a product?

A chemical reaction is when substances (reactants) change into other substances (products). The five general types of chemical reactions are synthesis (also known as direct combination), decomposition, single replacement (also known as single displacement), double replacement (also known as double displacement), and combustion. In this lab, the five general types of chemical reactions were conducted and observations were taken before, during, and after the reaction. Then the reactants and observations were used to determine the products to form a balanced chemical equation. The purpose of this lab was to learn and answer the question: How can observations be used to determine the identity of substances produced in a chemical reaction?

* By using the dropper and measuring cylinder, an amount of 5ml milk was placed in the test tube

“Fire!” I yelled as I pulled back the arm of the catapult, and quickly releasing it to have the marshmallow soar through the air. In this paragraph I will be writing about my catapult, and how far it fired, and also the accuracy, and finally how I built it. First, I had to construct my catapult we e were each given 16 rubber bands and 11 popsicle sticks. It was very challenging to tie the rubber bands to the popsicle sticks because there was a special way to tie the rubber bands, but I finally triumphed, I got all my rubber bands tied on. I figured out that if you tied the rubber bands to tight your catapult would start leaning and that’s what happened to mine, but if you tied them to lose your catapult would collapse. Second, I had to test

In trial A, the amount of baking soda was 5mL. For the first launch the lid did not go, so the amount was 0cm. For the second launch, the ingredients leaked out and there was nothing, so the amount was 0cm again. For the third launch, the lid snapped on, it dribbled, and then it shot across the room. The distance was at 244cm, even though it was low it was the first one to shoot. The average distance ended up to be 80.6cm.

The purpose of this experiment was to determine if rubber bands or bungee cord would put more force into the launch of the catapult. The experiment was designed to test the hypothesis if either a bungee cord or rubber bands would help an eraser to launch further, because of more force.

In the third experiment, I will program a computer to repeat my throwing cylinders experiment repeatedly to get more accurate results. I believe that this experiment will be just as accurate as my second experiment because I expect after 200 repeats the results won 't get much more accurate.

The average distance was 1.27 meters (Data Table 1).The marble was also launched at an angle of 25 degrees and a height of 1.05 meters. The average distance was 1.46 meters (Data Table 2). The marble took .452 seconds to hit the ground (Figure 1). The marble had an average velocity of 2.82 m/s (Figure 2). A triangle was drawn with a magnitude of 2.82 m/s. The x and y components of the triangle were calculated.

The second attempt it was 440cm and it was leaking vinegar but I pop the cap in time so it could pop and it made a boom sound. The third attempt it was 318.5cm and after it pop it left a salt residue that smelled like chips.

Repeat Steps 1-7 two more times, but with the launcher set at a different angle other than 45 degrees. In this experiment,

The one that went further was the 16-meter one which is the one with the less clay on it. In this lab, we are trying to test different variables in order to figure out which one will fly further. We had to drop weight from a high thing. This is what made it fly further.

Another element that could of affected the result was my motion of my hand caused on the marble released into a tube at the release point as it could of had extra kinetic energy in rolling through the tube and emerging to the launch point. However, I made sure that I would apply the same amount of force when dropping the marble and to redo trials if my movement interfered with the results. I also made sure that I released the marble at the right place instead of further up or down the tube sometimes. In addition, another possible component that could influence my calculations was the speed of my hand when stopping the timer. In order to made sure that my time was accurate, I had placed the timer in front of the horizontal distance and utilized my camera to record the exact time.

This data was tested using a pound of soft, polymer clay, a small Jolly Rancher candy, ruler, pencil, and a measuring tape. The Jolly Rancher weighed 6 grams. The pencil was placed underneath the middle of the ruler for balance. On one end, I placed the Jolly Rancher and dropped the clay on the other end. I started dropping the clay from 107 centimeters. The measuring tape was placed behind the pencil and ruler. I then video-taped the event to pinpoint the exact launch height of the candy. The first experiment had no force

To conduct the experiment, make the straw rocket launcher. Place rocket in the rocket launcher and launch. When done, measure how far rocket went in meters. Make sure to do 3 to 5 trials switching the two.

The experiment conducted was to observe how changing factors, including nose cone designs and volume of water would affect a water rockets maximum vertical displacement and the forces involved. It was hypothesised that the round cone would travel a greater distance in comparison to the square and pointed cones. Another assumption that was made was the water rocket with the 750 ml volume of water would be the most effective and would travel the greatest distance in comparison to the 500ml and 1000ml volumes of water. As seen from the results collected, it suggests that these hypotheses were supported and matched the expected outcomes with experimental errors and uncertainties.
