Catalase Lab Report

610 Words3 Pages

The experiment was to test the if the efficiency of the enzyme catalase was affected by the temperature of its surroundings, by putting hydrogen peroxide on chicken liver (which has the enzyme catalase) in different temperatures. The results of the experiment showed that in a cool environment (about 20℃), the reaction with catalase and hydrogen peroxide produced about 10 ml of water, a moderate amount of bubbles (compared to the other 2 samples), and released 3℃ of heat the first trial and 1℃ of heat the second trial. This could mean that the reaction is an exothermic reaction, because there is heat being released during the reaction. However, in the same experiment done in room temperature (about 24℃), there were much less bubbles, only 6 ml of water produced, and there was no change in the temperature. Lastly, the experiment done in a warm environment (30℃) showed much more change. Much more bubbles were produced than the other 2 experiments, 12 ml of water was produced and the temperature dropped 2℃. …show more content…

Both the amount of oxygen and the amount of water produced increased as the temperature increased. According to the data collected, the experiment done in 20℃ and 24℃ produced 10 ml and 6 ml of water, while the experiment done in 30℃ had 12 ml of water in its product. Obviously more water was made in the reaction in 30℃. Additionally, the experiments in the cool and room temperature surroundings had a moderate to not a lot of bubbles, meanwhile the experiment in 30℃ had much more bubbles, in other words it produced more

Hand Warm Lab Report

Our objective was to pick the best chemical to be used in a hand warm. This chemical had to be cheap, relatively safe, and must raise the temperature by 20oC and no more. We add 6 different chemicals to water we record the inshell temperature and then add one a the 6 chemicals to the water and record the temperature change of the water. We also add cold water hot water together to find how much heat would escape the calorimeter. We found that the calorimeter absorbed 71.1J/oC. Then this information to calculate the energy that was released by all of the chemical reaction.

How Fast Does Alka Seltzer Make Gas

621 Words | 3 Pages

The control in the experiment is water. Units used while timing the productivity of gas from an Alka-Seltzer tablet in different temperatures is, seconds. In order to find out if temperature controls the rate of chemical reaction, whether hot water is a more effective way to make the gas produce at a faster speed, it would be necessary to compare the results of different temperatures at the end of each trial. In order to do this the scientists will measure the volume of gas that is produced within a 10 second interval time after the tablet begins to react.

How Do Alkaseltzer Tablets Affect The Boiling Point Of Water

”(Scientific American) These bubbles are representative of a chemical change and the resulting carbon dioxide should increase the water 's density. This may actually increase the volume of the water taking longer to boil, this difference may be minuscule, even negligible, but there 's a possibility for distinct change in results. This scientific American puts it best “For the reaction to occur,

They tested how the temperature would affect the rate of reaction. This was observed by the amount of time it took for the solution to change colors. For many chemical reactions there is an optimum temperature at which the chemicals will react with each other. As was found in their experiment, the temperature affected the rate of reaction. (Deoudes, 2010).

Procedure The various solids and liquids were used for this lab. The first experiment had effects of the temperature towards the chemical reaction. The first experiment had two test tubes filled with same amount of substances to react, but one was at 10 ºC while the other one was at 50 ºC. The second experiment involved different molar concentration of substances reacting. Individual test tube was filled with 1.0,

Salt Water Hydration Lab Report

These results were worthwhile as it can be useful to assist high-intensity endurance athletes to maintain peak performance through hydration. In these events, liquids are not readily available so it is useful to know which liquid evaporates the slowest so that they can get the most out of a liquid, and hence the hydration out of that given drink, in this case, it is Salt Water. It's also useful to assist people when exploring deserts or hot countries like Australia. In hot climates, liquids evaporate faster as more energy is present. This experiment is useful for tourists, so that they know to stay hydrated and make sure they are always covered in any situation in the areas of hydration.

Gas Law Lab

450 Words | 2 Pages

This lab contains two experiments that both test the knowledge of the gas law and how it applies to the state that is necessary to form a cloud and to calculate the rate of effusion of CO2 (carbon dioxide) leaving a balloon. If carbon dioxide is placed into a balloon for a period of time, then the carbon dioxide will effuse out of the balloon at a linear rate, because of the pressure that the gas is placing on the wall of the balloon that will allow it to escape from the balloon's microscopic pores. If a match is placed into a flask with room temperature water and heated water, then the resulting cloud that forms in the heated water will have a higher volume and a higher pressure than the cloud that forms in the room temperature water. The

Introduction The intent of this experiment is to understand how hot and cold water interact with each other by combining clear hot water and black ice cold water. I hope to learn more about how hot and cold water interact with each other. As of now, I know that cold water is denser than hot water. Knowing this I formed my hypothesis.

Furthermore, the value attained for the calorimeter constant was 0.1748 KJ/°C, this value allowed to apply the correction for heat loss to the calorimeter. However, during the calculation for the calorimeter constant, the assumption that the specific heat of water was 4.184 J 〖deg〗^(-1) g^(-1). The concentration of NaOH was attained when assuming no heat loss was 0.8170 M and including the heat loss the concentration of NaOH was 0.9493 M. These values are very close to the expected value of the concentration, which is 1.071M considering the experimental error is only about 11 percent off.

H20 + 2 O2 This experiment will use 1% catalase solution and 3% hydrogen peroxide solution, both diluted into water so the reaction slows down. Temperature will be controlled in this experiment to change the reaction speed of the enzyme and the substrate, this is what the experiment is looking at. The effect of the temperature will be determined by how much gas is released in two minutes, which will change the pressure inside the test tube and will be measured by a gas

Calorimeter Experiment

1525 Words | 7 Pages

Introduction Heat is the form of energy, thermal energy, which flows between two substances due to their difference in temperature.1 The measurement of heat flow is called Calorimetry and the apparatus used to measure the heat flow (temperature change) for a reacting system is called a calorimeter. The calorimeter is well-insulated device that help to minimize the heat exchange between the system being observed and its surroundings. In this experiment, simple calorimeter, coffer cup calorimeter containing Styrofoam cups is used. Calorimeter contains a thermometer and a stirrer.3 Thermometer is typically inserted in the calorimeter to measure the change in the temperature that results from the reaction.

Furthermore, my data compared to other resources are fairly similar. The rate of reaction approximately doubles every time the temperature increases by the 10°C (Ingram, Paul). Whereas my rate of reactions double every 20°C instead of 10°C. This tells me that I was not accurate enough with my timing and measuring. The results of the experiment was as predicted and more successful than I thought it was going to

Boiling And Boiling Lab Report

Theoretical Background of Experiment  The behaviour of the water while it’s evaporated in close container faces various stages. “Boiling contender” • Free conductive heating (no boiling): in this stage, as the heat flux is very low, no boiling occurs. However, there is a slight swirling in the water movement at the bottom as well as phase change which occurs at the free surface as evaporation. • Onset of nucleate boiling: as heat flux is increased, phase change will occur at the heater surface and vapour of bubbles will formed at the heater and rise to the free surface and later condense, as they have reached the cooler fluid. During this, small bubbles condensing on the surfaces of glass may be seen.
