Abstract:- The experiment illustrates the relationship between the limiting reagent and the amount of product produced as a result of a chemical reaction. The chemical reaction was carried out by mixing the solution of Na2CO3 and CaCl2 and the precipitates of CaCO3 were obtained as a product. The experiment was carried out in 4 trials in order to determine the limiting reagent and the actual yield of the product obtained. In the first three trials, Calcium Chloride was the limiting reagent and…

each white powder including the mystery powder with four different liquids. The liquids were; water, universal indicator, vinegar, and iodine. For example, when they mix the four liquids with the powder, one of the powders should have the exact same chemical and physical reactions as the mystery powder does. If none of the powders match the…

Can Fireworks Explode without Being Lit? Fireworks exploding on the night sky is a majestic sight. These explosives look stunning but they are still just that, explosives. In order to enjoy them, you want to keep in mind the safety rules and follow instructions. But could something go wrong? Can fireworks explode without being lit? How do fireworks work? Fireworks come in different types from rockets to wheels. But each firework will have a fuse, which is the main part of the firework in…

Enzymes are biological molecules macromolecules that catalyze chemical reactions. Enzymes are usually proteins; however, it has been discovered that some enzymes are RNA molecules. The molecules at the beginning of the process to which enzymes act upon are called substrates, which are converted to the products by the actions of the enzyme. Almost all metabolic processes require enzymes to catalyze reactions to a rate that is fast enough to sustain life. Enzymes increase the rate of the reaction…

In this project the aim is to determine the equilibrium constant (Kc) of a weak base when it reacts with a weak acid. The chemicals I wish to determine the equilibrium constant for are, Ethanoic acid (CH3COOH) and Propanol (C3H7OH). To accomplish this, the first question we must ask is, “what is an equilibrium constant and how is it determined”? There are 2 different types of equilibrium. The first, and the type we shall be using is known as homogeneous equilibrium which has everything present…

Molecules are a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction. Molecules are three-dimensional entities and therefore should be depicted in three dimensions. My group decided on the claim that as electrons are bonded to a central atom, the greater the electron repulsion, causing an increase in the bond angles. Bond angles are the angles that are formed between two adjacent bonds on the same central…

6.3 Results and Discussion 6.3.1 The influence of high pressure on the kinetics of α-chymotrypsin The choice was determined by the fact that the catalytic mechanism as well as pressure stability of this enzyme is well established. α-chymotrypsin-catalyzed hydrolysis proceed according to the Michaelis–Menten mechanism. The initial process involves creation of a stable enzyme substrate complex ES, which is related to KM, afterwards activation of the ES^≠ and subsequent reaction steps occur,…

My Element is the Most Important Element (Argon) •Atomic mass 39.948 •Atomic Number -18 •Gas at 298 K •Density-0.0017837 grams per cubic centimeter •Third Noble gas •Chemical Symbol-Ar •It is also obtained from the air as a byproduct of the production of oxygen and nitrogen •It is the third most atmospheric gas •Argon is colorless and odorless •Argon is non reactive and has no effect on living organisms •Makes up 1% of the air around •Argon is found in the earth’s crust…

Nerve agents are chemicals which are used for warfare purposes in attempts to kill mass amounts of soldiers. This form of warfare has become so heartless, that even Adolf Hitler himself refrained from using them against the Allied Forces during the Second World War. Nerve agents are all based around phosphorus. In the 1930s, the very first nerve agent of the “G Series” was created. This is known as the “G-Series” due to the fact they were all originated in Germany. There are four types of nerve…

Chandross of Bell Labs’ oxalyl chloride and hydrogen peroxide glow stick was patented in 1960’s. Chemiluminescence is a luminescence resulting from a chemical reaction which is how glow sticks work. A glow sticks has a glass vial, a small glass or plastic bottle for holding medicines, and you break the glass by bending the stick. This then causes the chemicals in the stick to mix and a reaction takes place. This experiment will test the length of time glow sticks radiate in different…
