Chemical reactions describe the changes between reactants (the initial substances that enter into the reaction) and products (the final substances that are present at the end of the reaction). Chemical equations are notations that used to concisely...

A chemical reaction is a transformation resulting from the interaction between two atoms or molecules. Reactions involve the breakage and reformation of the chemical bonds which hold atoms together and can therefore cause changes in the structure or...

The number of possible chemical reactions is so vast that chemists have divided them into categories. Although there is no single, universally recognized classification schemes, there are relatively few classification schemes and some very important...

A chemical reaction is a process that results in the interconversion of chemical substances.[1] The substance or substances initially involved in a chemical reaction are called reactants. Chemical reactions are usually characterized by a chemical...

Pressure for federal safety standards builds as experts warn of the threat of a terror attack on chemical plants It turns out all those not-so-scenic vistas of chemical plants and tank farms along the New Jersey Turnpike are more than just fodder for...

With petrochemical expansions making up a sizeable portion of more than $6 billion in new construction for the Baton Rouge metropolitan area, it's one of the vital economic drivers this year. "We'll have a very stable petrochemical industry for the remainder of this...

A German scientist received a startling present Wednesday on his 71st birthday: a $1.5 million Nobel Prize to honor his groundbreaking studies of how chemical reactions take place on surfaces.Gerhard Ertl laid the foundation for studies of modern surface chemistry, a field that will help...

Chance of showers during the 2008 Beijing Olympics: 50 percent. But Chinese meteorologists have a plan to bring sunshine. The meteorologists say they can force rain in the days before the Olympics, through a process known as cloud-seeding, to clean the air and ensure clear...

What a chemical reaction is and different types of chemical reactions are described: Hydrogen Peroxide and Manganese Dioxide; Silver Nitrate and Copper Foil; Sodium Hydroxide and Phenolphthalein; Carbon Dioxide and Magnesium Ribbon; Sodium Hydrogen Carbonate and Lime Water; Copper Foil and Yellow Solid Chalk; Ammonium Hydroxide and Copper (II) Nitrate.

An overview of an experiment to test the effects of concentration on the rate of reaction between a magnesium ribbon and hydrochloric acid. Includes an outline of the experiment and an analysis of its results.
