There are 5 easy steps to making a lava lamp Step 1: Fill the bottle 3/4 of the way full with vegetable oil then top it off with water and about 10 drops of food coloring (or enough to make the solution appear fairly dark). Step 2: Cut an Alka-Seltzer tablet into pieces. You can either ration the pieces

Then an Alka-Seltzer tablet was added‚ quickly covered with a cap and was observed until the film cap popped off. The time was then immediately recorded and the procedure was the repeated three times each with whole and crushed Alka-Seltzer tablets. Then results from three fellow classmates’ experiments would be recorded and added to our own results. The hypothesis was that more surface area exposed and smaller volume would result in a faster chemical reaction of the material. Since the Alka-Seltzer

by mass of NaCO3 in Alka-Seltzer Tablets Alka-Seltzer is an effervescent antacid typically used for pain relief and neutralizing stomach acid to alleviate indigestion. Alka-Seltzer tablets contain Aspirin‚ Citric Acid (CH3COOH)‚ and Sodium Bicarbonate (NaCO3). When the tablet is placed in water it undergoes an acid-base reaction and Carbon Dioxide (CO2) is a byproduct that causes the notorious “Fizz”. The objective of the lab was to measure the % of NaCO3 in an Alka-Seltzer tablet in different

Alka Seltzer Expirement Research The Expirement that the chemist will be conducting includes the following materials: hot water‚ room tepmerature water‚ cold water‚ and regular Alka Seltzer tablets. Research on Alka Seltzer in previous expirements shows that it dissolves faster in hotter temperatures of water. It also shows in previous expirements that Alka Seltzer dissolves slower in colder temperatures of water rather than hotter temoeratures. Alka Seltzer is an antacid that contains aspirin

What factors will make an Alka-Seltzer tablet dissolve faster? My theory is that the Alka-Seltzer will dissolve faster in the warm water and slower in the cold water because the more heat something has the more energy the atoms or molecules in the object get. So in hot water the molecules inside are moving around really fast and have tons of energy to dissolve the tablet while in cold water the molecules are still moving around but at a slower pace therefore taking longer to dissolve the tablet.

The name of the alka seltzer project is named “The Dropouts.” The significance of that name is that the owners of the machine are very close to dropping out school themselves. Ultimately‚ the goal of the machine would be to pop a balloon and to blow out a candle. The goal would be achieved by using the potential energy in the balloon‚ popping it‚ and using the now present kinetic energy‚ which is the air‚ to blow out the flame of the candle. The final products would be a popped balloon and a blown

Interview with Alka (Mom) Alka found it rather easy to narrow down her musical choices to three. "I don’t listen to much variety in music. I only listen to about four artists. “She stated. Alka said she would listen to more music if she had more free time. A male singer who she loves listening to is Jagjit Singh. His voice is very sweet‚ and melodic. Alka’s favorite female singer is Lata Mangeshkar. She describes Lata Mangeshkar’s voice as being heavenly‚ and really relaxing. When it comes to groups

The purpose of this lab was to determine if a there is a change in mass when a gas is produced and determine if gas has mass. To conduct this experiment‚ the group must be careful not to let the Alka-Seltzer tablet get wet before the bottle is closed by wiping the lip of the bottle and the cap so it remains dry‚ or risk gas escaping into the air and not being captured by the bottle. Also‚ the group must be sure to close the bottle tightly with the cap‚ because gas may escape this way as well. During

Reactions’ lab is to learn how to plan an investigative lab without outside help and to learn about the ‘Rates of Reactions’. This lab will require students to take responsibility for their own learning and use their prior knowledge to aid in the completion of this lab. In the lab prepared below‚ students will be learning about Rates of Reaction with varying concentrations of Alka-Seltzer with water. Hypothesis: I believe that the more water added to the canister with the Alka-Seltzer tablet‚ the
