The intent of this study is to depict the electrochemical industry of Cl and Na hydrated oxide. Chlorine today is used globally to maintain the environment free from pollution. It can clean and disinfect the H2O from pathogens. NaOH is besides a utile merchandise in many facets such as purification of bauxite for the extraction…

Stromatolites are rock-like constructions of multi-layered sheets of micro-organisms ( microbic mats ) that form in limestone. Stromatolites by and large form from the caparison and binding of atoms by micro-organisms e. g. algae and bacterium. and turn upward to acquire light from photosynthesis. Stromatolites provide scientists with some of the oldest records of early…

Protons are positively charged and form the nucleus of an atom with neutrons that carry no charge. Electrons are negatively charged and are constantly moving around the nucleus. Ions are created when electrons move from one atom to another atom changing the charge of that atom to either positive or negative. When electrons move they…

The objective of the laboratory experiment was to synthesize cyclohexene from cyclohexanol by utilizing an acid-catalyzed dehydration process. To accomplish this, an elimination reaction was conducted. Initially, the alcohol’s oxygen was protonated, resulting in the formation of an oxonium ion. This substitution effectively replaced the poor leaving group (OH) with a more favorable leaving group…

What is an “Expansive Soil”? Expansive soils contain minerals such as smectite clays that are capable of absorbing water. When they absorb water they increase in volume. The more water they absorb the more their volume increases. Expansions of ten percent or more are not uncommon. This change in volume can exert enough force on…

Antigens usually bind to the side chain of the antigen binding site of the antibody, which may either be a protein, polypeptide or lipid. Antigens and antibody interactions are mediated by non-covalent bonds such as electrostatic forces, van der Waals forces and hydrophobic forces. Binding mediated by this type of bonds produces a reversible reaction….

Dyes may be defined as compounds that, when applied to a substrate provide coloring material by a procedure that alters, at least temporarily, any crystal construction of the colored substances. Such substances with considerable coloring capacity are widely employed in the fabric, pharmaceutical, nutrient, cosmetics, plastics, photographic and paper industries. The dyes can adhere to…

Plants utilize nutrition in the form of inorganic minerals for growth and development. Plant nutrients can be divided into two groups and these are macronutrients and micronutrients. Macronutrients are elements required by plants in relatively large quantities and these include Carbon (C), hydrogen (H), oxygen (O), phosphorus (P), potassium(K), nitrogen (N), sulfur (S), magnesium (Mg)…

Mild SteelIntroduction:Steel is not a single alloy rather it a generic name for iron based alloys or an alloy which has Iron (Fe) as the major component. Based on the alloying elements in iron we have different classes of steel. For example Fe with 12 or more wt% of chromium (Cr) is stainless steel, which…

There are many different types of grounds that can be found at a offense scene, these can be categorised into chemical, physical and biological grounds. Physical grounds can be collected at the offense scene and are chiefly physical objects such as a slaying arm or a broken window. Chemical grounds is any residue from liquids…
