Atoms are the simplest form of matter. On Earth matter can be a solid, liquid, or a gas. The atoms that create the states of matter also create elements. Currently, there are organized on a chart known as the periodic table, one such element is Germanium. In fact, Germanium has a symbol known as Ge. A symbol is a shorter way to represent the element. All elements have a symbol, atomic mass, atomic number, and a number of protons, neutrons, and electrons. Germanium’s atomic mass is 72.64, this…

The tarnishing of silver is due to a chemical 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…

The Periodic table is a table that organizes the different known elements, and Neon is one of those elements. Neon is an element that is a non-metal and also a noble gas. The start of the element, Neon, was when a Scottish chemist named William Ramsay discovered Neon, Krypton, and Argon, which are all noble gasses ("Periodic Table of Elements: Los Alamos National Laboratory." Periodic Table of Elements: Los Alamos National Laboratory). For this achievement, William Ramsay won the Nobel Prize in…

For much of human history, salt has been mined from the areas around dry lake beds and in deposits left after ancient seas dried up. These bodies of water all evaporated, leaving their crystallized salt deposits behind. Mined salt is sourced from these deposits. It differs from sea salt in that sea salt is taken from living oceans. While it is usually ground finely for sprinkling onto food as table salt, some of it is kept in a coarse and chunky form that is referred to as rock salt. Rock salt…

DISCUSSION 2-Bromoheptane + Potassium TertButoxide The 2-Bromoheptane + Potassium TertButoxide reaction yielded 3 different products: 1-heptene, Cis-2-heptene and Trans-2-heptene. However, the major product constituent was 1-heptene. Because Potassium TertButoxide is a bulky base, steric hindrance prevents it from attacking a hydrogen on a highly substituted carbon. Consequently, the base attacks a hydrogen on the least substituted carbon (primary carbon). In this case, steric hindrance is…

In this lab, we did four kind of different test, to mimic the chemistry of digestion. The first one was to test for sugar. We used a dropper and measured 2 ml of maltose and 2 ml of benedict’s solution in a pyrex test tube. After, using a test tube holder, we placed the test tube in a boiling water bath and heated for 5 min. After the 5 min, using a test tube holder we removed the test tube from the water bath. We then repeated the same procedure using starch solution instead of maltose. When we…

The synthesis started with the [3+2] cycloaddition between chiral nitrone 128 and allyl cyanide under microwave activation at 110°C in toluene to provide cycloadduct 2 in 96% yield as a single isomer (Scheme 1).The regioselectivity was identical to that observed for diverse terminal alkenes, with attack on the terminal methylene by the electrophilic carbon of the nitrone, presumably due to both steric and electronic reasons.29a-f The stereoselectivity results from the approach of allyl cyanide…

solution, which was our dependent variable. An enzyme is a catalyst, and it has two fundamental characteristics that it is known for. One of these things it that it can increase the rate of a chemical reaction without being changed or destroyed in the reaction. The second is that they don’t alter the chemical equilibrium between the reactants and the products while they speed up the reaction. In enzyme catalysis, the substrate, which can also be referred to as the reactant, is transformed…

the liver and hydrogen peroxide were 10℃ also. The liver was put into a 100mL measuring cylinder and the hydrogen peroxide was also poured in as the timer was started. After twenty seconds, several millilitres of froth had been produced from the chemical concoction. This froth was recorded into a results table, and the previous steps were repeated but with increasing temperature increments of 10℃ until 50℃. After carefully completing the experiment, the final results obtained by measuring the…

1a) Yes, there is a correlation between the structures and the observed volatilities of compounds in Step (1a) and Step (1b). In Step (1a), n-pentane had the highest vapor pressure because the compound evaporated the fastest. N-heptane had the second highest vapor pressure, followed by n-decane with the lowest vapor pressure. The molecular structure correlates with the volatility because of the molecular weight for each compound. N-pentane is the lightest compound, followed by n-heptane and…
