What is meant by oxidation and reduction processes? What is meant by anode and cathode? Write both half reaction equations and total equations in an electrochemical cell that consists of Pb and Zn in their respective 1M ion solutions. Write both half reaction from the …
A membrane is a type of selective barrier that is used to separate or concentrate the feed stream as it passes through the membrane, which selectively allows some constituents to pass as others are retained on the surface of the membrane. The constituents that are …
“MRI contrast is used for a variety of reasons. Primarily, it is used to improve the detection of disease; that is, to increase sensitivity and diagnostic confidence, to enhance the ability to differentiate normal and abnormal tissue; and to identify the extent of the disease” …
We all live on the planet that provides us everything; we do not go anywhere else for anything. We get all we need on Earth. It might sound odd but its true and we take it for granted. In certain cultures, the Earth is called …
Until the nineteenth century industrial revolution, the power of C had fuelled the moving ridge of economic development which has delivered the modern society ‘s greatest achievements such as electric lighting, cars and flights. However in the latter half of the century it was noted …
Methane Recovery from Landfills Utilization as a Potential Energy Source and Impact on Reduction of Green House Gasses According to The Conference Board of Canada, current Canadian municipal solid waste (MSW) generation levels are approximately 30 million tonnes per year, with a rate of 894 …
A chemical substance (typically, a corrosive or sour-tasting liquid) that neutralizes alkalis, dissolves some metals, and turns litmus red.

THE EFFECTS OF Migration Since the 1950’s migration has by no means on a small scale. The main reason people from the Caribbean migrate is to make a better type for themselves and their families. Many sacrifices are made when West Indians deceive their home …
Determination of an Equilibrium Constant Objectives: To study the chemical reaction of Fe3+ and SCN- to produce Fe(SCN)2+ in aqueous solution. To measure concentrations of ions in a solution using a spectrophotometer. To determine the equilibrium constant of this reaction at a given temperature. Procedure: …
Streams or rivers are bodies of water that constantly travel from its source, which is usually a mountain or an underground source, towards an exit point into the sea. These bodies of water carry different kinds of materials. There are three kinds of loads that …
Breathing into a wrapping tube that’s quite long will most likely have the same effect as when breathing through a paper bag, a practice most commonly associated with trying to relieve hyperventilation. Although the wrapping tube is open at the other end and will not …
Abstraction This paper shows the function of sludge keeping clip in aerophilic granulation under negligible hydraulic choice force per unit area. Consequences showed that no successful aerophilic granulation was observed at the studied SRTs in the scope of six-eight months. A comparing analysis revealed that …
Although water-assisted injection moulding is a relatively new and advanced technique to produce hollow parts, several problems which reduce the product quality can occur. Namely, water inclusions in the wall, severe fingering and double wall defects reduce the product part stiffness. This study investigated the …

Conjugation
The word "conjugation" is derived from a Latin word that means "to link together". In organic chemistry terms, it is used to describe the situation that occurs when π systems (e.g. double bonds) are "linked together". An "isolated" π (pi) system exists only between a single pair of adjacent atoms (e.g. C=C)
Kinetic energy
Kinetic energy is the energy associated with objects in motion. Potential energy is the type of energy associated with an object's potential to do work. Chemical energy is the type of energy released from the breakdown of chemical bonds and can be harnessed for metabolic processes.
Physics
Chemical physics is concerned with the application of the concepts and theories of physics to the analysis of chemical systems and their physical behaviour. While also at the interface between physics and chemistry, it is distinct from physical chemistry.
