Essays on Chemical Formula

Introduction

There are environmental chemical processes which require light to react. These processes are called photochemical reactions. Photochemical reaction is commonly initiated due to the absorption of solar energy or light. When molecules absorb energy in the form of light, the atoms are converted in a transient excited state (Larson & Weber, 1994). This transition state or excited has completely different physical and chemical properties with the initial state of the molecule. The excited states also have more tendencies to react since they are considered stronger acids and stronger reductants that the initial state of the molecule. The excited state of ...

What is the chemical formula for ozone gas?

Ozone is present in the troposphere, a part of the atmosphere. Ozone consist of 3 molecules of Oxygen. The chemical formula for ozone is O3. Ozone is also called as tri-oxygen since it consists of 3 molecules of oxygen bound to each other by covalent bonds. The structure and formula of ozone were identified in the year 1865. However, it is less stable than Oxygen and blue in color.

How does ozone form in the stratosphere?

Ozone is found in both, the stratosphere and the troposphere. The formation of ozone in both these layers is distinct. Stratospheric ozone is formed in two simple steps. Initial step involves ...

Minerals are classified by their chemical composition as Silicates, Phosphorites, carbonates, and halides are all major mineral groups.

Silicates contain silicon (Si) and oxygen (O), the two most abundant elements in the earth and comprise the majority of Earth's crust. They have a chemical formula SiO2. Common silicate minerals include olivine, pyroxene, amphibole, mica and quartz.

Phosphorites are sedimentary rocks of biochemical origin and are rich in phosphate with chemical formula PO4. They are mostly used as chemical fertilizers. They are also used as food preservatives, anti-corrosion agent and also in the field of metallurgy. Limestone and mudstone are common phosphate bearing rocks.Carbonates are the minerals mostly found in the Earth’s near surface crust. They have ...

Introduction

There are many resemblances that can be observed in magnetic and electric phenomena. A magnet comprised of north and south poles which are opposite to each other. The opposite poles attract and likewise repel each other. A magnet has principle property to influence the surrounding space. This surrounding effect of a magnet is known as a magnetic field. Magnetic fields consist of lines of force and force of attraction and repulsion that travel/or move along the lines. The developed forces depend on strength and distance apart the poles. Figure 1: Magnetic lines of force for bar magnet A ...

1- The chapter opens with these words: “ Neeru, shouei, maima, aqua. In any language, water is the most abundant compound on the surface of the Earth.” - Explain the term compound and also why water is not an element. Answer: Compound is a chemical entity made from combination of two or more different elements. These elements lose their individual identities when they combine to form a compound and possess unique properties subjected to that compound. Water is made from two molecules of hydrogen and one molecule of oxygen. Hydrogen and oxygen individually are elements but when combined in the ...

Abstract

Eveslogite, ((Ca,K,Na,Sr,Ba)48[(Ti,Nb,Fe,Mn)12(OH)12Si48O144](F,OH,Cl)14), is a mineral found on Mt. Eveslogchorr in khibiny Massif, Kola peninsula, Russia. It derives its name from this locality, in particular from Mt. Evesglochorr. This mineral occurs as an anchimonomineral veinlet that cross-cuts poikilitic nephiline synite (Hawthorne 2012). This mineral appears to resemble Yuksporite since it forms similar placated fine-fibrous of approximately 0.05 to 0.005mm that aggregates outwardly. The color of Eveslogite is yellow or rather light brown. In addition it is a semitransparent mineral that has a white streak and a vitreous luster. ...

PART A

The works in question Scenting Ltd sells perfumes and toiletries for both men and women which smell like other expensive brands. The company’s products bear writing on them indicating that they “smell like” an expensive brand. For example one of their products, “Dawn” smells like “Naissance” which is produced by a French company called Chic SARL. “Dawn’s” packaging has words indicating that the company’s testers differentiate between “Dawn” and “Naissance”. When the Chic SARL Company moves to court on copyright infringement grounds, Scenting Ltd maintains that there is no copyright infringement. This is a summary of the ...
