What is Chemistry? Chemistry is the study of matter and energy and the interactions between them. This is also the definition for physics‚ by the way. Chemistry and physics are specializations of physical science. Chemistry tends to focus on the properties of substances and the interactions between different types of matter‚ particularly reactions that involve electrons. Physics tends to focus more on the nuclear part of the atom‚ as well as the subatomic realm. Really‚ they are two sides of the

Sustainable Chemistry Terry Collins* Chemistry has an important role to play in achieving a sustainable civilization on Earth. The present economy remains utterly dependent on a massive inward flow of natural resources that includes vast amounts of nonrenewables. This is followed by a reverse flow of economically spent matter back to the ecosphere. Chemical sustainability problems are determined largely by these economy-ecosphere materials flows (see the figure‚ below)‚ which current chemistry education

Chemistry of cosmetics Few people would whip out a chemistry set‚ uncork the vials‚ and slap the compounds on their face. Yet‚ millions of women and girls essentially do that every day when they unzip their makeup bags and apply lipstick‚ mascara‚ and other makeup. Like the compounds in a chemistry set‚ makeup consists of chemicals. Although the chemicals in cosmetic products are intended to improve the appearance of skin‚ lips‚ and lashes‚ some can cause adverse effects. Emulsions The majority
