Metal oxide and Lean flame – signal is decreased, more oxygen for reaction with metal. Example : Determination of Vanadium in presence of Al and Ti. Fuel rich flame – gives higher absorbance for V because the little oxygen present in flame will be captured by the Al and Ti, and more V atoms available.

0 List of Harmful Chemical Reactions | Healthfully
Chemical weapons are the most dangerous, harmful chemical reactions ever made 1. They are built to be destructive, and that is exactly what they are. Chemical weapons, such as the atom bo, use several different chemical reactions to produce large amounts of heated gas--which not only causes a huge explosion, but produces gases that can be harmful to people hundreds of miles away 1 .

What Is Chemical Weathering? With Examples | Science …
Chemical weathering is the process of breaking down rocks using a chemical means, such as acids, bacteria, or enzymes. Weathering should not be confused with erosion. While both involve the changing of something from its original state, erosion is the process of removing parts of a material from its original loion to another.
