Hydrogen

Initially, sand and hydrogen peroxide were added in a test tube to create a mixture. Based on the observation conducted, no reaction was visible (i.e. no gas occurred). In result, the solution did not react because it does not contain the desired enzyme in order to break down H2O2. An enzyme is needed to decompose H2O2 into water and oxygen. With this knowledge, students were able to determine that the results for the rest of the tests did make sense. For example, the solution contained…

Step (1a) include only dispersion forces, because each of the compounds are non-polar. In Step (1b), there are dispersion forces, hydrogen bonding, and dipole-dipole forces. Dispersion forces occur in all compounds, hydrogen bonding occurs between the oxygen and hydrogen atoms within each of the compounds, and there is also a dipole movement between the oxygen and hydrogen atoms. There is a correlation between IMFs and volatilities, as the stronger intermolecular forces tend to evaporate the…

product obtained will be different. Primary alcohols have one carbon and two hydrogen atoms attached will produce aldehyde and then to carboxylic acid in two steps by oxidation. While secondary alcohols have two carbon atoms and one hydrogen atom attached will produce ketone by oxidation (Kotz, et al., 2015) Aldehydes, the compounds that the carbonyl group has a hydrogen atom attached to it together with either a second hydrogen atom or a hydrocarbon group. Ketones are the compounds that two…

The Hydrogen Bomb (aka “Hell Bomb”) was first created and tested by America in 1950. Three years later the soviet union constructed and tested the Hydrogen Bomb as well. Now both America and the soviet union both were in possession of super bombs. Most of America was afraid of going into nuclear war with the soviet union for the first time in history. The Hydrogen bomb is ten times more powerful than the atomic bomb dropped on japan during world war 2. “Mike” vaporized an entire island in the…

reaction between silver and hydrogen sulfide, producing silver sulfide and hydrogen gas. The balanced chemical equation is 2Ag (s) + H2S (g) → Ag2S (s) + H2. This is a single replacement reaction. This reaction most commonly occurs through contact with hydrogen sulfide in the air - although direct contact with substances that contain sulfur can cause tarnishing. Silver tarnishes very quickly when it is exposed to air that contains high levels of ozone, sulfur, or hydrogen sulfide. Silver…

Intermolecular Forces Intermolecular forces are the result of attractive or repulsive forces between atoms, molecules or ions, primarily as a result of electrostatic attractions; these forces act between discrete molecules. Intermolecular forces are weak forces but without them life as we know it would not be possible: water vapor would not condense into its liquid (or solid forms) if its molecules did not attract each other, and all matter, in fact, would exist as gases. The physical states…

volume of hydrogen gas would be off. Ultimately the measured volume of hydrogen gas would be too high because the gas being recorded would not only include hydrogen gas, but the air that leaked into the eudiometer as well. Because the volume of hydrogen gas would be too high the calculated molar volume of hydrogen would also be too high. This is because to find the calculated molar volume of hydrogen you divide the recorded volume of hydrogen gas by the theoretical number of moles of hydrogen.…

CONTENTS RESEARCH QUESTION How does the length of carbon chains, specifically those related to alkanols, namely ethanol 1- propanol and 1- butanol, affect the heat of combustion? AIM To investigate how the length of carbon chains affect the heat of combustion and enthalpy, in order to determine which fuel would be the safest and most efficient to take on a camping trip. HYPOTHESIS If the number of carbon atoms in an alkanol is increased, then the alkanol containing the longest carbon…

reflecting the 4 distinct types of hydrogen. The area represented by the 4 peaks was 10, which…

In the Acid-Catalyzed Hydration of norbornene, water and sulfuric acid were added to the C=C double bond to form norborneol. Sulfuric acid acted as a catalyst, where it was not consumed in the reaction and helped to propel the reaction forward, as it was vital in forming hydronium ion and breaking the double bond. Both the products endo-norborneol and exo-norborneol were synthesized; however regioselectivity and stereoselectivity played a role as to which product was more preferred and whether…
