... A chemical property relates to a substance’s ability to undergo changes that transform it into different substances. An example would be the ability of charcoal to burn in air to form carbon dioxide, and iron rusting to form iron oxide. A chemical change is a change in which one or more substances ...

The melting of ice, the freezing of water, the conversion of water to steam, and the condensation of steam to water are all examples of physical changes. We know that these physical properties of water are the same for ...

Registration, Evaluation, Authorisation and Restriction of Chemicals
Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) is a European Union regulation dated 18 December 2006. REACH addresses the production and use of chemical substances, and their potential impacts on both human health and the environment. Its 849 pages took seven years to pass, and it has been described as the most complex legislation in the Union's history and the most important in 20 years. It is the strictest law to date regulating chemical substances and will affect industries throughout the world. REACH entered into force in 1 June 2007, with a phased implementation over the next decade. The regulation also established the European Chemicals Agency, which manages the technical, scientific and administrative aspects of REACH.
