... CONSERVATION OF MASS • Law of conservation of mass: mass is neither created or destroyed during a reaction. • The atoms form new bonds and thus are present after reaction only bound to some other atoms. • E.g. 2H2(g) + O2(g) 2H2O(l); 2 g of H2 plus 16 g of O2 produce how many grams of water? ...

Energy exchange at high T has a smaller impact on the entropy of the surroundings as its particles already have access to many different states. On the other hand, an energy transfer at low T should affect t ...

The phrase “Less of them” when discussing the amount of a substance is correct, not the phrase “Less of it”. The difference is in the word “them”. That indicates a numbe ...

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.
