Sodium melts almost at once to form a small ball that dashes around the surface. . If the sodium becomes trapped on the side of the container‚ the hydrogen may catch fire to burn with an orange flame ii) Write a word and symbol equation for the reaction. sodium + water → sodium hydroxide + hydrogen 2Na + 2H2O → 2NaOH + H2 iii) what would be the effect of the solution

Chlorine kid is 35.45 years old. Chlorine kid never ages after his incident from getting his powers‚ so‚ he’s technically only 4 years old. Chlorine kid got his powers after swimming in a swimming pool with too much chlorine and this is how it happened. Just that morning before chlorine kids parents took him swimming the manager of the pool refilled the pool with chlorine‚ while he was doing that the chlorine bucket slipped out of his hands and the chlorine overflowed the pool because of how much

Emilia Monroe August 27‚ 2014 Experiment #01 The Determination of the Percent of Water in a Compound CHEM 1315-022 For experiment one‚ The Determination of the Percent of Water in a Compound‚ the sole purpose of conducting this experiment was to determine the percent of water found in compounds such as Magnesium Sulfate‚ Copper Sulfate‚ and so on. Along with determining the percentages of the hygroscopic compounds the experiment allowed for the exploration of separation of hydrogen bonds

Chemical Kinetics: The Iodine-Clock Reaction: S2O82−(aq) + 2 I−(aq) → I2(aq) + 2 SO42−(aq) To measure the rate of this reaction we must measure the rate of concentration change of one of the reactants or products. Here‚ it is convenient to carry out a clock reaction involving the product I2. To do this‚ you will include (to the reacting S2O82− and I−) i) a small (but accurately known) amount of sodium thiosulfate‚ Na2S2O3‚ and ii) some starch indicator. The added Na2S2O3 does not interfere with

occur in different temperatures determined by the use of an electric water bath. With these results‚ the effect of temperature on the rate of reaction will be investigated. 2. Determine the activation enthalpy with and without the catalyst ammonium molybdate(VI) and with different protic acids and use this to compare the effectiveness. To find out which catalyst is most effective‚ this aim will be carried out as an iodine clock reaction. The goal of this aim is to find out what catalyst

Determination is a positive emotion that involves persevering towards a difficult goal in spite of obstacles.[1][2] Determination occurs prior to goal attainment and serves to motivate behavior that will help achieve one’s goal. Empirical research suggests that people consider determination to be an emotion; in other words‚ determination is not just a cognitive state‚ but rather an affective state.[3] In the psychology literature‚ researchers have studied determination under other terms‚ including

The Iodine Clock Investigation Introduction This is an investigation into the rate of a reaction and the factors that contribute to how fast a reaction will take place. Through the recording and analysis of raw data‚ this investigation also allows us to apply generally accepted scientific rules and to test them against results gained from accurate experimental procedures. Aim The aim of this experiment is to investigate the rate at which iodine is formed when the concentration

ELECTROLOYSIS OF WATER: DETERMINATION OF THE FUNDAMENTAL ELECTRONIC CHARGE PURPOSE: The fundamental electronic charge of water will be determined. A system of collecting the formation of H2 and O2 using two inverted glass collections tubes and a 1-L beaker filled with water will be setup. An electrolyte (H2SO4) will be added to water to make it an electrical conductor. A small amount of electricity will be applied to the water (roughly 400 mA) to oxidize the oxygen and reduce the hydrogen

experiment:11-20-13 Date submitted: 11-23-13 Determination of Water Hardness Using a Titrator Purpose: This purpose of this experiment was to determine the hardness of the local water supply. Be familiar with using a titrator. To tell wether your water is hard or soft. Hard water however does not create a threat‚ but is bad for your pipes causing them to crust. To measure water’s “softness” you are truly measuring the amount of CaCO3 in the water. Procedure: Assemble the titration and stockpot

Chlorine in Photosynthesis Experiment Abstract Photosynthesis the means by which green plants and different types of organisms use light from the sun to synthesize foods from CO2 and H2O. Chlorine is a chemical element usually in the form of a yellow-green gas and is a strong oxidizing agent. Elodea is a type of aquatic plant also known as waterweed that is native to North America. In the experiment that took place‚ the effect of chlorine in the presence of photosynthesis reactions were studied
