ANFO stands for ammonium nitrate/fuel oil (most often diesel fuel, sometimes kerosene). It is by far the most widely used explosive in coal mining, quarrying, metal mining, and civil construction: it accounts for an estimated 80% of the 6,000,000,000 pounds (2,700,000 metric tons) of explosive used annually in North America. ANFO under most conditions is considered a high explosive: it decomposes through detonation rather than deflagration and with a high velocity of detonation. It is a secondary explosive consisting of distinc ...

A zero-order reaction is independent of the concentration of the reactants. Increasing the concentration of the reacting species will not speed up the rate of the reaction. Zero-order reactions are typically found when a material required for the reaction to proceed, such as a surface or a catalyst, is saturated by the reactants. The rate law for a zero-order reaction is If, and only if, this zero-order reaction 1) occurs in a closed system, 2) there is no net build-up of intermediates and 3) there are no other reactions occurring, it can be shown by solving a Mass ...

A first-order reaction depends on the concentration of only one reactant (a unimolecular reaction). Other reactants can be present, but each will be zero-order. The rate law for a first-order reaction is If, and only if, this first-order reaction 1) occurs in a closed system, 2) there is no net build-up of intermediates and 3) there are no other reactions occurring, it can be shown by solving a Mass balance for the system that The integrate ...

Chemoluminescence takes place in numerous living organisms, the American firefly being a widely studied case of bioluminescence. The firefly reaction has the highest known quantum efficiency, QC of 88%, for chemoluminescence reactions. ATP (adenosine tri-phosphate), the ubiquitous biological energy source, reacts with luciferin with the aid of the enzyme luciferase to yield an intermediate complex. This complex combines with oxygen to produce a highly fluorescent compound. ...

Synthesis of molecules in a combinatorial fashion can quickly lead to large numbers of molecules. For example, a molecule with three points of diversity (R1, R2, and R3) can generate possible structures, where , , and are the number of different substituents utilized. Although combinatorial chemistry has only really been taken up by industry since the 1990s, its roots can be seen as far back as the 1960s when a researcher at Rockefeller University, Bruce Merrifield, started investigating the solid-phase synthesis of peptides. In the 1980s researcher H. Mario Geysen developed this technique further, cre ...

Photosynthesis is a physiological phenomenon that coverts solar energy into photochemical energy. This physiological phenomenon may be described thermodynamically in terms of changes in energy, entropy and free energy. The energetics of photosynthesis, driven by light, causes a change in entropy that in turn yields a usable source of energy for the plant. The following chemical equation summarizes the products and reactants of photosynthesis in the typical green photosynthesizing plant: CO2 + H2O â ...

Enzymatic Chemiluminescence (ECL) is a common technique for a variety of detection assays in biology. an horseradish peroxidase molecule (HRP) is tethered to the molecule of interest (usually by immunoglobulin staining). This then locally catalyzes the conversion of the ECL reagent into a sensitized reagent, which on further oxidation by hydrogen peroxide, produces a triplet (excited) carbonyl which emits light when it decays to the singlet carbonyl. The mechanism of ...

Catalysts enable reactions to occur much faster or at lower temperatures because of changes that they induce in the reactants. Catalysts provide an alternative pathway of lower activation energy, for a reaction to proceed whilst remaining chemically unchanged themselves. This can be observed on a Boltzmann distribution and energy profile diagram. This means that catalysts reduce the amount of energy needed to start a chemical reaction. Molecules that would not have had the energy to react or that have such low energies that they probably wou ...

The active components in a secondary cell are the chemicals that make up the anode, cathode, and electrolyte. The anode and cathode are made up of different materials, both of which react with the electrolyte, causing ionic bonding. If these chemicals are known, predictions on maximum voltage and currents of the cells can be made. Example: Nickel Metal Hydride Nickel oxyhydroxide (NiOOH) is the active component in the cathode, while the anode is composed of hydrogen in the form of metal hydride. The electrolyte of this secon ...

Fuel cell - Environmental effects. A common misconception among the public is that elemental hydrogen is a source of energy. This is not the case, hydrogen is not a primary source of energy: it is only an energy storage medium, and must be manufactured using energy from other sources. The physical laws relating to the conservation of energy unfortunately create a situation where the energy needed to create the fuel in the first place may reduce the ultimate energy efficiency of the system to below t ...

A collision between reactant molecules may or may not result in a successful reaction. The outcome depends on factors such as the relative kinetic energy, relative orientation and internal energy of the molecules. Even if the collision partners form an activated complex they are not bound to go on and form products, and instead the complex may fall apart back to the reactants. ...

Dissolution of an organic solid can be described as an equilibrium between the substance in its solid and dissolved forms: We can write an equilibrium expression for this reaction, as for any chemical reaction (products over reactants): where K is called the equilibrium (or solubility) constant and the square brackets mean molar concentration in mol/L (sometimes called molarity with symbol M). Because the concentration of a solid doesn't make sense, we use the curly ...
