«When a new substance forms during a chemical reaction, many students think that the atoms and molecules have actually changed into something new, whereas they simply rearranged, that the mass increase of plants is due to minerals in the soil, or that cell division alone accounts for animal growth,» said Cari Herrmann Abell, a senior research associate at Project 2061.

The scientists used a chemical detection device called a proton - transfer reaction mass spectrometer to, for the first time, track the odors emitted by flowers in the wild just as moths might encounter them.

The privately funded Space Studies Institute, which he ran in Princeton, built working models of «mass drivers», electromagnetic launchers for putting payloads into lunar orbit, and commissioned investigations into the most efficient chemical reactions for extracting oxygen and other useful elements from the Moon.

Research & teaching: multiphase chemistry in the Earth system, climate and public health, i.e., chemical reactions, mass transport and phase transitions of gases, liquids and solids linking the atmosphere, biosphere and hydrosphere on molecular to global scales.

Using the total energies of these phases obtained in first - principle calculations, we calculate the Gibbs free energy changes in the corresponding chemical reactions, and subsequently evaluate the equilibrium concentrations of the phases in every sample according to the law of mass action.

E = MC2 also tells us that the mass of the reactants is the same as the mass of the products in a chemical reaction (Lavoisier 1770's) and law of conservation of energy in that particular reaction are not right.
