Mrs. Batcha 816 December 2017 Research paper How does temperature affect the speed of a chemical reaction? How the temperature affects the chemical reaction rate is by increasing the temperature causes molecules to move faster, so there’s an increased chance of them colliding with each...

Although it is a metal, it is soft enough to cut with a knife. It is so light it can float on water. Lithium fires are difficult to put out. You can’t use water as water will react with the lithium and could make the...

A titration is a commonly used laboratory technique where a solution of a known concentration (the titrant) is used to determine the concentration of another solution (analyte). We slowly add the known solution with a buret to the unknown solution until it reaches neutralization, indicating...

Introduction The metathesis reaction has emerged as one of the most powerful tool for the formation of C-C bonds in organic chemistry and materials science. This prominent role has been awarded with the Nobel Prize in Chemistry 2005 “for the development of the metathesis method...

ACID RAIN: DEFINITION: Precipitation or rain with a high concentration of acids produced by, nitrogen dioxide, sulphur dioxide and other such gases which result from the combustion of fossil fuels. This has a destructive effect on buildings, aquatic life, and plant. Certain pollutants in the...

Silver will be An rather inert metal. This may be in light its filled 4d shell is not exceptionally viable done protecting the electrostatic constrains about fascination from the core of the peripheral 5s electron, What’s more henceforth silver will be close to the base...

“Towards digital soil morphometric”, author described how proximal soil sensing and other tools can be used in soil profile descriptions where techniques and toolkits have not changed in the past decades. Digital soil morph metrics is defined as the application of tools and techniques for...

Acrylamide (AA) has a toxic effect on both animals and human. The present study investigated the potential protective effect of silymarin (SIL), as an antioxidant against the toxicity of the AA in cardiac tissue. Rats were divided into four groups as follows: The control, AA,...

The power sharing curves of islanded MG when supplying nonlinear loads, star connected and delta connected three phase unbalanced loads are illustrated in Fig (). As depicted from figures, at the beginning the three-phase six-pulse diode-bridge rectifier of RL load is connected up to t=2.5...

Silica gel is an important adsorbent use as desiccant in our daily life. The term ‘gel’ merely indicates the condition of the material it is a hard glassy substance as it is manufactured from raw material. It has different characterization parameters It has porous structure...

Solvation defines the interaction of solvent with molecules or ions of a solute. Ions, and to some cases, molecules, perform along intensely with solvent, and also the strength and nature of this interaction results some properties of the solute, additionally to solubility, reactivity, and color....

The increasing interest on new drug discovery is frequently advanced as drugs do not increase endurance adequately against increasing cancer cases worldwide. Molecular hybridization is a new concept in drug design and growth based on the combination of pharmacophoric moieties of different bioactive substances to...
