Science Rocket Experiment
By : Julia Sánchez
Background Information:
This experiment is about firing a rocket, we are creating hydrogen gas. We had to fill the bottle with hydrogen gas and then put a flame under the bottle and measure how much it flew upwards. To do this we mixed magnesium strips into hydrochloric acid. A combustion reaction takes place in this experiment. The investigation topic is about the fuel that makes a space rocket fire. A combustion reaction is more known as burning. Combustion isn’t always burning, but when it is, the flame causes most of the reaction ( in our case, to make our bottle fire up ). We light the fire with a match, the heat from the flame may provide the sufficient energy to to make the reaction happen.

Take a tray full of water ( preferably deep )
Fill your plastic water bottle full of water ( without a bubble of gas )
Put your hand on the bottle
Insert this to your bottle upside down ( like in the diagram )
Set this aside
Then, pour hydrochloric acid into the conical flask ( about 50 - 90ml )
Insert the delivery tube carefully under the bottle and hold it straight
Drop the magnesium into the conical flask.
As soon as possible put the bung on.
After no more bubbles come out, you quickly light up the match and put it under the tripod
Quickly, you take the bottle out of the water ( with no water ) and then place it on the tripod straight up.
You place the match under the cap of the bottle ( without the cap on ) and then the bottle should fire up.
If it doesn’t fire up you should record your result as 0.
Repeat this experiment with different amounts of magnesium stripes

I had predicted that the more magnesium stripes there were in the acid, the higher the bottle would go. This was wrong, as the less magnesium strips you had, the higher the bottle would go.
The graph results tell you that when the bottle went the highest was when the number of magnesium stripes was 3. When we had only used 1 magnesium strip, the bottle didn’t go up a bit, that’s why we got the result of 0 each time. When the bottle had 5 magnesium strips, it didn’t fly up as much as when the bottle was half way full of hydrogen gas. You can see that when we only had 1 strip and 5 strips of magnesium, the bottle didn’t fly up much. The highest the bottle got was to 179cm tall, the highest we had.
I’ve found an anomaly, it is when we put 3 magnesium stripes to create hydrogen gas. The anomaly is 47 cm, whilst the other results are 179 cm. This could be because we changed person doing a job every time, so the pressure was either too loose or too tight. Also, this could have been because the bottle had been to much in the tripod without being fired, so the bottle lost its hydrogen gas. Also because of the matches, it couldn’t have lit on time. There was a bit of mistakes in the experiment of 2 magnesium strips. As you can see they aren’t similar at all. My results are reliable from the results 2, 3, 4, 5 . On number 2, they aren’t very reliable as the results increase by each test we do, they go ; 20 - 67 - 179 . This could have been

DH=-285.5 kJ/mol. In this investigation, we will be working with potentially dangerous chemicals and safety precautions must be made. Magnesium oxide is a respiratory and eye irritant, the dust must not be inhaled and all work with MgO should be conducted in the fume hood ( Cartwright, 2002). Hydrochloric acid is extremely corrosive, inhalation of the vapor can cause serious injury, ingestion could be fatal, and the liquid can cause severe damage to the skin and eyes; when working with HCl splash goggles and gloves should be worn, and work should be conducted in a well ventilated area (Cartwright, 2002). Materials and Methods --------------------- Goggles - Lab apron - Magnesium oxide MgO - 1g. Lab balance 100mL graduated cylinder Hydrochloric acid HCl - 200mL/.5M. - 2 plastic foam cups - thermometer - cover for cup - Magnesium (Mg) ribbon - 600mL beaker (base for calorimeter) - 400mL beaker (transportation of acid).
4. Pour about 300mL of tap water into the beaker. Set up a hot-water bath using a hot plate, retort stand, and thermometer clamp. Alternatively, use a Bunsen burner, retort stand, ring clamp, thermometer clamp, and wire gauze.
The first step that we took to accomplish our goal was to put on our safety goggles and choose a lab station to work at. We received one 400ml beaker, one polyethylene pipet, two test tubes with hole rubber stoppers, two small pieces of magnesium (Mg), one thermometer and a vial of hydrochloric acid (HCl). We took the 400ml beaker and filled it about 2/3 full of water (H20) that was 18 OC. Then we measured our pieces of Mg at 1.5 cm and determined that their mass was 1.36*10-2 g. We filled the pipet 2/3 full of HCl and poured it into one of the test tubes. Then, we covered the HCl with just enough H2O so that no H2O would be displaced when the stopper was inserted. After inserting the stopper, we placed the Mg strip into the hole, inverted the test tube and placed it in the 400ml beaker. HCl is heavier than H2O, so it floated from the tube, into the bottom of the beaker, reacting with the Mg along the way to produce hydrogen gas (H2). We then measured the volume of the H2, cleaned up our equipment and performed the experiment a second time.
Now, assemble and arrange all of the needed supplies so that they are easily accessible. Connect the IV tubing to the solution bag and allow the fluid in the bag to run through the entire length of the tubing, also known as priming the tubing. When this is done, clamp the tubing closed. You will then need to tear several pieces of tape, six to eight inche...
Without touching the tip of the bottle, gentle squeeze the bottle to let one drop fall into the space formed in your lower eyelid.
First of all, you need a sturdy, good tube. The tube should be cylindrical and should be at least 3/32 of an inch thick. The opening at the top of your tube should have a 5/8 inch opening. Then take a 1/16 inch fuse, make sure it covers the whole tube and sticks out a little bit, just like any other firework and keep the tube in place by using tape. Next, 1.25 grams of 3F BP should be poured into the tube.
concentrated, so the reaction slows down. This graph shows this: -. volume of hydrogen Time Diluted Acid Concentrated Acid = Acid particle = water molecule = Magnesium atom TEMPERATURE - at low temperatures the particles of reacting substances. don't have enough energy?
In 1232, the Chinese would take sulfur, saltpeter, and charcoal dust and used it to make an early form of gunpowder. Leather and tubes of bamboo were closed off and filled with the gunpowder. A fountain of sparks or a bang was produced when ignited. Therefore, the rocket was born. Later, in the 13th to 15th century, there were many records of rocket experiments, such as using new forms of gunpowder to greatly increase to the range of rockets.
Aim: The aim of this experiment was to determine the empirical formula of magnesium oxide.
We began the alkali metals with lithium, the first in the group. Lithium caused a strong reaction when added to the water. The water bubbled and the reaction made a sizzling noise. The lithium piece at the bottom of the tube spun around until it dissolved. When we added the burning splint, it made a popping noise, but rather than immediately extinguishing, a red flame was briefly lit on the mouth of the test tube.
2. In the large beaker, put water and boil it completely. After that, remove the beaker from heat. 3. Sample tubes (A-D) should be labeled and capped tightly.
If there is not enough energy no reaction takes place. The sand is In a solution of 0.5M hydrochloric acid, there is less hydrochloric. acid particles compared to that of 2M hydrochloric acid, therefore,. there are less particles to react with magnesium particles thus meaning less chance of collisions between the two reactants. [ IMAGE] Therefore, as the concentration of the hydrochloric acid is increased.
3 cm of magnesium ribbon generally has a mass of 0.04 g and yields 40 cm3 of hydrogen when reacted with excess acid. 50 cm3 of 1M hydrochloric in this experiment is in excess.
This is because the 10cm3 of water has replaced 10cm3 of acid molecules, so now there are less acid molecules to collide with the Mg ribbon. = Magnesium molecule = Hydrochloric acid molecule = Movement Planning 2: [IMAGE]Magnesium + Hydrochloric Acid Magnesium Chloride + Hydrogen [IMAGE]Mg + 2HCL (aq) MgCl2 + H2 (g) The information in the paragraph that follows was researched from a secondary source, which enabled me to further plan my investigation. According to the collision theory, the more concentrated the reaction the greater the number of collisions between reactant molecules.
