compare that relative reactivity of Na and k -Sodium and potassium react somewhat similar when reacting with water however they are slightly different. Sodium moves because of the hydrogen coming off of it and has a low melting point while potassium’s reaction is faster and enough heat is produced to set light to the hydrogen coming off of it. Each leaves a pink color hue in the water. Discuss the similarities and differences in the behavior of the metals tested with water relative to their positions

ab: Observing a Chemical Reaction Name: Deja Eason Period: 5th Period Partners: Melingh Patterson‚ Tori Millens Date Performed: 9/2/11 Teacher: Mrs. Medina Abstract: This experiment was all about observing a chemical reaction. During the experiment‚ we made observations and possible explanations on why Copper(II)Chloride Dehydrate and Aluminum foil created a chemical reaction. The observations were made by using Copper Chloride‚ Aluminum foil‚ and Distilled water. Before the Aluminum

this lab we can learn to observe physical properties of varying substances as well as to use chemical reactions to observe chemical observe the chemical properties of varying substances. In experiment #1‚ we were able to detect physical properties of the aluminum and copper sulfate simply by looking at the substances. We then combined the two substances to see if they would create a chemical reaction and test the chemical properties. After being combined‚ bubbles and gas were created and the color of

Predicting Your Competitor’s Reaction In order for a company to gain competitive advantage in the consumer/business markets it needs to not only carefully prepare its “plan of action”‚ but also analyze‚ study and predict its competitors reaction to its strategic move. However‚ many companies undermine the importance of such analysis due to its complication in nature. But study shows‚ unlike in chess‚ where you have to predict up to hundreds of combinations that follow each possible move‚ most

goal was to observe and note the reaction of butanols with hydrobromic acid. Before the lab began we discussed and proposed mechanisms. (see “Mechanisms”) To begin this experiment we calculated how much of each material we were going to be using‚ and the numbers we chose to use differed from our reference text slightly. We used 6.5 mL of our assigned butanol and only 4 mL of sulfuric acid. Going back to our reaction mechanisms‚ we were looking at SN1 and SN2 reactions‚ so we of course used the hydrobromic

the value of the sum for Reaction 1 and Reaction 2’s change in temperature‚ compared to Reaction 3’s change in temperature. Reaction 1 was the dissolution of solid sodium hydroxide in water with a ΔH°rxn of -47047 J/mol‚ Reaction 2 was the neutralization of liquid sodium hydroxide with HCl with a ΔH°rxn of -31289 J/mol and Reaction 3 was the dissolution and neutralization of solid NaOH with HCl with a ΔH°rxn of -91000 J/mol. Consequently‚ the sum of Reaction 1 and Reaction 2 was -78336 J/mol‚ similar

affecting the rate of reaction‚ PNPP (p-nitrophenyl phosphate) + H20 ? PNP (p-nitrophenol) + H3P04. This reaction is catalyzed by the enzyme phosphatase. Different environments produced different reaction rates as environmental factors affect the efficiency of phosphatase. This is because environmental factors can change the tertiary structure of phosphatase‚ which alters its active site‚ and thus changes its efficiency to catalyze the reaction. We measured the rate of reaction‚ by using a chromogenic
