them to survive. The Bayer™ company concluded that the dissolving time of Alka-Seltzer is faster in warmer water than in cold water.2 The increase in water temperature increases the collision rate which increases the rate the products are formed.1 If the experiment followed the Q10 model than the reaction rate would double for each 10°C temperature interval and therefore mimic the mammalian Q10 effect. If the Alka-Seltzer tablets are dissolved in water at increasing temperature intervals‚ then the

flight I could have made my rocket shorter and thinner because the smaller the mass the greater acceleration. Doing this would improve the acceleration of the projectile in this case the rocket. Also to improve the acceleration I could add more alka-seltzer to the film case. Doing this would add a greater force to push off of which would make the rocket go higher and faster. Lastly I could have made the structure for the rocket more aerodynamic. To do this I would make the flaps triangles that

*The mass should not have changed because the mass is conserved* • Experiment Four: In a chemical change‚ the mass is conserved What you will need: Ziploc Bag filled with 20 ml of water Balance or Scale One Alka-Seltzer Tablet Procedure: 1. Find the weight of the Alka-Seltzer tablet and the weight of the Ziploc bag containing the 20ml of water. 2. Once both masses are recorded‚ add the tablet to the water and quickly close the Ziploc

The different methods of measuring acids and bases in a solution By Starsky Intro to Biology September 26‚ 2011 Lab Partners: Kristen‚ Tania and Betty Introduction When using different methods to measure pH levels there are some tools that can be useful. Some more than others but by putting into action the different methods it may determine which tools will work best and give the best

seen as a catalyst. The reason collision theory relates to this experiment is due to the fact that the catalyst creates a higher activation energy and this causes more collisions‚ which increases the reaction rate. In the second experiment‚ the Alka Seltzer tablet was

As placing a small piece of Zn(mossy zinc) metal into the test tube containing the diluted HCI(Hydrochloric Acid) solution‚ gas bubbles rose from the solution slowly at the beginning and vigorously in process of time. As this reaction continued for a long time‚ transparent solution turned into white opaque color and black precipitates were formed

1. Dancing Raisins Here’s another quick and easy science experiment. All you need is a glass of clear soda‚ such as ginger ale or club soda‚ and several small raisins. Fill a glass with soda. Leave about ½ inch (12.5 mm) of space at the top. Drop the raisins in. Those tiny bubbles attaching themselves to the raisins are carbon dioxide (CO2) bubbles. The irregular surface of the raisins enables a lot of CO2 to accumulate. When enough gas bubbles attach to the raisins‚ they act like tiny balloons

not required to conduct the experiment‚ but it may be beneficial to do so if you can acquire the materials needed for your design. The reaction that you will be investigating is the reaction that occurs when an Alka-Seltzer tablet is placed into a given amount of water. Alka-Seltzer is an over-the-counter antacid and pain relief medication that is dissolved in water before it is ingested. Each tablet contains aspirin (acetylsalicylic acid)‚ citric acid‚ and sodium bicarbonate. As the tablet dissolves

06/21-06/22 Purpose: The purpose of this experiment is to examine different properties of gases in order to be able to identify them in a laboratory setting. I will be using Hydrochloric acid‚ mossy zinc‚ Bromothymol blue‚ limewater‚ Manganese‚ and Alka Seltzer‚ to test different properties of gases formed by chemical reactions. In order to extract the gas I will use several household products such as vinegar‚ baking soda‚ water‚ and hydrogen peroxide in order to create the gases to be tested.
