Hydrogen peroxide

Joseph Priestley was a famous chemist. He was famous for inventing soda water, his writings about electricity, and his discovery of gases. Joseph was born on March 24, 1733, in Bristall. He died February 6, 1804 at the age of 70. Joseph is most known for his discovery of oxygen and for isolating it. Oxygen was not first discovered by Joseph, instead the famous Swedish chemist, Carl W. Scheele, in 1772. Joseph discovered Oxygen independently in 1774. Joseph published his findings in the…

this property it contains hydrogen bonding as well as dipole-dipole forces, two of the strongest and most significant forces that affect the solubility of the solution. Each separate group has hydrogen’s bonded on to the group, so either the oxygen’s having…

the reaction occurred. Figure 2 shows the reaction in action. Before long less Zinc became visible at the bottom of the beaker. Copper became visible at the bottom of the beaker all at the same time. The bottom of the beaker released bubbles, or hydrogen gas, from the reaction. The reaction for this particular experiment is a single replacement reaction. This means that a single element replaces a second element in a compound. The reaction is shown…

When a hydrogen atom of an alkane is replaced by halogens, they become an alkyl halide compound which can also be called haloalkanes. There are two types of reaction within the alkyl halides. When another atom replaces the halide ion, the reaction becomes a substitution reaction, and when the halide ion leaves with another atom or ion, it becomes an elimination reaction (Weldegirma, 2015). The substitution reaction can be divided into either electrophilic substitution or nucleophilic…

Chromate The Prefix word “poly” implies to the word many, but even ions of two atoms are usually referred to as polyatomic. Majority of the Polyatomic ions that are used with Oxygen will have the word “ate” in them. Nitrate is an example of a Polyatomic Ion. Polyatomic Ions are referred to as a radical, and less commonly, as a radical group. There are many differences between a polyatomic ion and a compound. Polyatomic ions are composed of two or more atoms that are linked to covalent…

indicating that the concentration of hydrogen ions increased significantly. With the base, NaOH, the pH of the tap water changed from 7 to 12 after 30 drops, indicating that the concentration of of hydrogen ions decreased significantly. These changes occurred in the tap water because there are no chemical buffers present in water. In the potato homogenate, when 30 drops of HCl were added the pH changed from 6 to 3.5 (a less significant increase in the concentration of hydrogen ions), and when 30…

The amino acid, homocysteine, is basically a cysteine with an added methylene bridge. Methionine, an essential amino acid, gives rise to homocysteine, a sulfur-containing amino acid, through the methionine cycle. Methionine is converted to S-adenosyl methionine (SAM) when an adenosine group from ATP is added on to activate methionine’s methyl group. SAM is a methyl donor that is a substrate used in many reactions. When it donates the methyl group, SAM is converted to S-adenosyl homocysteine…

TASK 4 CORRELATING STRUCTURE ACTIVITY RELATIONSHIPS Task 4 aims to develop knowledge of the relationship between the structure of ENMs and their toxicity. In this study, different kinds of metal oxide nanoparticles, carbon nanotubes, and graphenes will be tested their toxicities and then their structures and their toxicities will be found their correlations. For MONMs, different coatings of ZnO will be tested toxicities and observed the relationships, while differences in their sizes and…

His company assigned Plunkett to research and work on synthesizing various new forms of refrigerants, like ammonia and sulfur dioxide. Ammonia (NH3) is one of the most commonly produced industrial chemicals in the United States. It is used in industry and commerce, and also exists naturally in humans and in the environment. The problem is that during that time ammonia was used in most refrigerators, and it was toxic and many food-industry workers died. His team worked very hard and researched…

Fluorine is an element on the periodic table. Fluorine atomic number is 9. Fluorine is a chemical that looks pale and yellow. The atomic weight is 18.9984032 and the density is 0.001696 grams per cubic centimeter. Fluorine is a non-medal the period number is 2 its group number is 17 and the halogen. Fluorine is a gas. Fluorine was discovered by Henri Moissanin 1886. Ferdinand Frederick Henri Moissan was a French chemist who won the 1906 Nobel Prize in Chemistry for his work in isolating…
