... By adding a nonvolatile solute to the water in the radiator, not only is the freezing point of the resulting solution substantially lower than the freezing point of water, the boiling point is raised substantially. Thus a water/ethylene glycol mixture protects the radiator both from freezing and fro ...

Coordination and Chemistry of Stable Cu (II) Complexes in the Gas
... A mixture of argon as a carrier gas and a solvent undergoes supersonic expansion through a pulsed conical nozzle. For ammonia, carbon dioxide, and ethene, high-pressure cylinders containing 99% Ar and 1% solvent were used to produce the required mixture of gases. For the remainder of solvents studie ...

... So why do chemists use maths? Mostly, because it’s good for describing patterns clearly and because it allows chemists to put a number on things: rather than saying something increases we’d like to be able to say by how much. This might mean that you find your chemistry teachers look at equations an ...
