A 125 mL flask was obtained. The square of aluminum was fashioned over the flask by laying the foil over the mouth and folding the sides down. A pin was then obtained and was used to poke a tiny hole in the center of the aluminum cap.…
5) The atomic umber of sulfur is 16. Sulfur combines with hydrogen sulfide. Based on the electron configuration of sulfur, we can predict that the molecular formula of the compound will be…
In this experiment we were wanting to find the specific heat of an unknown metal and determining what metal it was by using the formula q=c X m X change of temperature. We did two trials to compare the two and see what we come up with.…
When you put a sample of N2O4, a colorless gas, in a closed container at 100C a reddish-brown color starts to show. This is due to NO2 formed by the decomp. of part of the original substance. The forward and reverse reactions are taking place at the same rate. The concentrations of species present remain constant with time. These concentrations are independent of the direction from which equilibrium is approached. The equilibrium constant K is where the partial pressures in atmospheres, is a constant, independent of the original composition, the volume of the container, or the total pressure.…
Phosphate is important for all organisms, soil, and water. Excess phosphorus indicates that the water is polluted and problems within the water begin to occur. Some include the growth of aquatic plants such as algae, bacteria will decompose dead plants, and fish die as a result of decomposition that removes the dissolved oxygen from the…
John Emsley is an author who loves to write books based on how chemistry has affected history, and this novel focuses on how the element of Phosphorus was found and how it was treated and observed throughout history. Emsley conducted research on how Phosphorus impacted the various societies that have had notable events routed from the element. Emsley goes all the way back to when the alchemists would try to alter the element to present day views on Phosphorus. The book digs deep into some specific vocabulary, so this book would be great for a extra credit assignment or optional project for a honors chemistry class made up of juniors and seniors. Phosphorus is a key component of DNA, so this book may connect AP biology and chemistry…

The human’s impact on The Phosphorus Cycle would have to be the Phosphorus that is mined in several locations around the world and is then made into fertilizers, animal feeds, detergents and other products.…
There are three importation cycles that the environment. The three cycles are carbon, phosphorus and nitrogen cycles. These cycles are part of photosynthesis. These are a chain that keeps everything going in the word. These cycles keep animal alive and plants and people breathing.…
The phosphorus cycle includes the cycle of all the biologically important nutrients found in the natural minerals. These elements include iron, calcium, potassium found in the rock and soil minerals in the lithosphere. Over time a rock breaks down and releases phosphate (PO43-) and other ions which replenish phosphorus that is lost due to runoffs and leaching. The phosphate is absorbed by plants and turned into compounds that are moved through the food chain. Humans impact this cycle because we are using the phosphorus to make fertilizers, animal feeds, detergents or other products…
Phosphorus is the best Element that you can buy in the market anywhere in the world for the use of fire to things like pesticide. Phosphorus was discovered in 1669 by a man named Hennig Brand in Hamburg,Germany when he was preparing it from buckets of urine because urine contains high quantities or dissolved phosphorus. The Element was named Phosphorus because it comes from a Greek word called phôs (light) and phoros (bearer) which means “bringer of of light”. Phosphorus which has the Element symbol of P is a highly reactive element that is a part of the Nitrogen family.…
Most people would use a lighter or a match to start a fire. Matches allow for a portable, easy-to-use source of fire. Many chemical reactions generate heat and fire, but matches are a fairly recent invention. Matches are also an invention you probably wouldn't choose to duplicate if civilization ended today or you were stranded on a desert island. The chemicals involved in modern matches are generally safe, but that wasn't always the case. The material of making a matches is red phosphorus.…
The most basic arrangement of the periodic table was in 1649. By this time, many elements have been known but the first scientific discovery of an element was in 1649. Hennig Brand discovered phosphorus, the first element discovered through scientific inquiry. He attempted to create a Philosopher’s Stone which was supposedly able to turn metals into pure gold. During his experiment, he heated residues from boiled urine, and a liquid dropped out and turned into flames. This was the first discovery of phosphorus. During the next 200 years were when chemists started to recognize patterns in properties of elements and gained much knowledge about the properties and compounds of them.…
A new study reveals that babies who were fed by rice cereals and other rice-based snacks have an increased level of arsenic in their urine compared with babies who were not fed rice. The study was issued in JAMA Pediatrics.…
