the wax from the candle is reacting with something else to make the flame. The substance that reacts with the candle wax is oxygen. It comes from the air. Putting the jar over the candle keeps oxygen ...

For example, ethene reacts with water (in the presence of heat and a catalyst) to produce the alcohol ethanol. Addition polymerisation uses addition reactions to turn alkenes into polymers.

Compounds such as ethanol, lactic acid, succinic acid and glycerol would then replace — or at least reduce our reliance on — fossil-based compounds such as ethene, propene, butadiene and benzene.

Methane is the most famous volatile organic compound (VOC) in our atmosphere. This week, our host George Zaidan follows up on a Reactions subscriber’s question about the 600 teragrams of a less famous ...

Chemical reactions make new chemicals. Atoms are rearranged during a chemical reaction, but the number of atoms does not change. Evidence of chemical reactions includes a large temperature change ...

Reaction Chemistry & Engineering Communications contain novel scientific work of such importance that rapid publication is desirable. Authors should briefly indicate in a covering letter the reasons ...

Sarah Vine and Andrew Pierce bring their own no-holds-barred opinions, insights and reaction (clue is in the title) to the biggest stories of the week. New episodes every Wednesday, wherever you ...
