Sodium Bicarbonate also referred to as baking soda, Bicarbonate of soda, Sodium hydrogen carbonate, and Carbonic Acid Monosodium salt, acts an ionic or salt compound when put in an aqueous solution. Its molecular weight is 84.006 g/mol and it is usually found in a dry powder form that is similar to slat. It is white, odorless, and has a melting point of 108.9 degrees Celsius. It has a density of 2.1 g/cm3.…
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 out candle.…
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. It is made in tablets that dissolve in water to give a fizzy reaction.…
In this experiment, we will develop five solutions that will be tested to figure which one of these solutions will dissolve an Alka seltzer tablet the fastest. The following essentials for this experiment will include Alka seltzer tablets that will be split in half. We will also use one solid tablet for a different result. This experiment will include water in different temperatures and additional ingredients such as ice, salt and vinegar that will be included to see which solution works more effectively. The Hypothesis: Hot boiling water will dissolve the Alka Seltzer tablet the fastest.…
A water bath was heated to about 70 degrees Celsius. One unknown tablet was weighed and then crushed…
Filled 600 mL beaker with ice, took temperature until it got to -10 c. The next step was to take 1 test tube with water placed in water bath, freezing point of distilled water -0.0 c.…
It was also assumed that both Sol.A and Sol.B beakers were exactly at the same temperature when the reaction occurred. Even though the temperatures of both beakers were recorded, it was highly likely that the temperature increased or decreased between the time when they were taken out of the water baths and the time they were mixed together. Though this would not be a primary source if error, nonetheless, it can account for a very small part of the experimental…
Hypothesis: Group 5 – The zinc and copper sulfate were the closet in amount. The distilled water was closer in amount with the copper sulfate as well, so the ratio between zinc, copper sulfate, and distilled water was the most equal and this would lead to the greatest temperature change.…
Actions Taken: I labeled six test tubes in accordance with their respective Sample number and placed them on the test tube rack. I then placed a pea-sized amount of each sample in their corresponding test tube. Following that, I utilized the graduated cylinder to measure and transfer 5 mL of distilled water into each of the six test tubes. I then placed a rubber stopper on Sample #1, and shook vigorously to determine its solubility. I repeated this with each sample, and then recorded my results in Data Table 1.…
The steps in the lab were to first start off with a burner, ice and water in a beaker, then record time and water temperature. Also, some phase changes in between. Our results were immediate, leading to safe and what I hoped would have happened. The difference between my data and the class’s data would have been a different amount of time the water took to boil. My result did agree with my hypothesis. There has been an error in the measuring since…
The purpose of this experiment was the reaction rate, and how surface area affected the reaction rate between water and alka seltzer tablets. The half crushed tablet had more particles in the tablet causing more surface area to dissolve in the water. The more surface area in the tablet, the more efficient it is in reacting in with water. Overall in my experiment, it was successful and it was a valid experiment. This experiment had taught me and to understand that the effect…
1. The framers created a bicameral legislature because of the Great Compromise at the Constitutional Convention which stated that one house’s representation will be based on a state’s population and the other would have equal representation. Another reason is that it would help prevent tyranny because both houses can “check” each other to make sure one does not get to powerful. One power unique to the House of Representatives is that revenue bills must originate from the House; the framers gave this power to the House because the House of Representatives is more representative of the entire population than the Senate is. One power unique to the Senate is that they are the ones that try the President for impeachment; the framers gave this power to the Senate because they reflect the state’s interests and also because they are more “mature” than the House of Representatives since the required age is higher.…
Objective: What is the relationship between temperature and the amount of light given off by the glow-stick?…
•Design two experiments that will compare two different factors that may affect the rate of the Alka-Seltzer reaction. Possible factors to be investigated include temperature, surface area, agitation, and amount of reactants. Remember to make sure there is only one independent variable in your experimental design for each…
Procedure: First a 400mL beaker was filled 2/3 full with ice. Next the time and temperature were recorded every minute for 18 minutes. All the data was recorded in a data table. Next the beaker was put on a hot plate and the temperature was taken and recorded every 30 seconds. Then the water was left to continue boiling for 5 more minutes and time and temperature were recorded every 30 seconds. Finally a graph of time and temperature was made.…
