AIM: To carry out a lab experiment to decompose a carbonate using heat‚ also to carry out appropriate tests for the formation of products as a result of this decomposition. DISSCUSION: Carbonates are decomposed by heat into the corresponding oxides and carbon dioxide. The temperature of decomposition depends upon the activity of the metal; that is to say‚ the more active the metal‚ the more stable is the carbonate. Thus‚ the carbonates of sodium and potassium are stable at the highest temperature

Factors that affect the rate of fermentation are the nutrient availability and the concentration of that nutrient. In the Barfing Bag experiment‚ our control group which was granulated sugar worked the best against splenda‚ artificial‚ and stevia which a sugar substitute that comes from a plant and has 0 calories. In the barfing bag experiment we had three bags with yeast and then we added different types of sugars to test which type of sugar creates the most carbon dioxide or which bag inflates

EXPERIMENT 5 TRANSVERSE STANDING WAVES A string attached to a turning fork is set vibrating at the same frequency as the tuning fork. The length and tension in the string are adjusted until standing waves are observed on the string. By knowing the tension in the string and the wavelength of the standing waves‚ the frequency of oscillation of the string and thus‚ the tuning fork is found. This value is then compared to a strobelight determination of the frequency. THEORY

Copper sulphate experiment Introduction There are a number of different methods of making salts‚ such as the reaction of a metal with an acid. Copper metal‚ however‚ does not react with sulphuric acid and so another method must be used. In this experiment a basic copper compound (copper(II) oxide) will be reacted with sulphuric acid giving copper(II) sulphate as one of the products. Method 1. Wear goggles and keep your face away from the beaker during the reaction 2. Place 20 cmm3 sulphuric

Lux G experiment is performed at the University of California San Diego on May 21st until June 4th of 2018 by Gloria Karem. This experiment is based on the purification of LuxG by using multiple purification and lysing methods: Brad Ford Assay‚ SDS-PAGE‚ affinity purification‚ lysozyme treatment‚ nickel column‚ sonication‚ and flavin reeducate activity assay. His-tagged protein is expressed in E. coli from pGhis‚ with the T7 RNA lac repressor induction system.5 Sonication is used‚ it’s why bacteria

social science “Milgram Experiments” were used to discover of the people would willingly hurt another person because someone of authority told them to do it but the participants were told that the purpose of the experiment was to study memory with punishments. Ethic and moral dilemmas appeared during the experiment that criticized the research and its methods because of its deception and stress that it puts on the volunteers. There are multiple reasons why the experiment could be used to show the

to certain scientific experiments‚ thought experiments also involve objects that are not found anywhere in nature. As mentioned earlier in this paper‚ genetically identical mice‚ which were used in an experiment to test whether or not a certain chemical caused lung cancer‚ are not found anywhere in nature — the genetically identical mice are a product of science. In this example‚ the elements of the experiment (the mice) were unnatural‚ yet the conclusion of the experiment yielded significant‚ real-world

NAZI MEDICAL EXPERIMENTS Nazi Medical Experiments Jean Paul Marion-Landais Jackson Memorial School of Radiology Abstract The Nazi Dr.’s performed a vast array of experiments on most if not all of the prisoners they held in their concentration camps. Such experiments caused a great deal of dilemmas across all the nations in the world. Headed by Dr. Josef Mengele one of the most controversial individual that has ever worn the label of Medical Doctor‚ the experiments dealt with how
