Electrons can spur the chemical reaction between an acid and a base, according to new results in Science, a finding that may help researchers precisely control reactions in areas from biology to ...

When writing chemical equations for reversible reactions, the usual one-way arrow is not used. Instead, two arrows are used, each with just half an arrowhead (⇌). The top one points right, and the ...

The word displace means to push out. A more reactive element can displace a less reactive element out of its compound during a chemical reaction. Displacement reactions can be used to investigate the ...

FOR the determination of vitamin A by means of the reaction of Carr and Price, the blue colour of the mixture is estimated with the Lovibond tintometer. If analysed by the spectroscope, the blue ...

Molecular self-assembly with DNA offers a route for building user-defined nanoscale objects, but an apparent requirement for magnesium in solution has limited the range of conditions for which ...
