A research team from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) has directly measured the masses of two highly unstable atomic nuclei, phosphorus-26 and sulfur-27.

Note that the mean energy of the collisions changes when the temperature changes. Not only does the rate of collisions increase, the proportion of collisions that are successful also increases. A ...

The greater the frequency of successful collisions between reactant particles, the greater the reaction rate. Temperature, concentration, pressure and the use of catalysts affect reaction rate. Heat ...

Note: This demo has two parts, I & II. When ordering, please specify whether you want Part I, Part II, or both at the same time. I. The reaction between iodate and bisulfite in acid medium produces ...

Molecular reactant Ball-and-stick model of carbon monoxide. The rate at which the molecule reacts with helium ions can be controlled using microwaves. (Courtesy: Benjah-bmm27) Through new experiments, ...

Some chemical reactions change temperature, change color, produce a gas, or make a solid from two liquids. Try this reaction and see what it does! Pour 1 tablespoon of hydrogen peroxide into a cup.

Photosynthetic electron transport reactions of succulent plants from hot deserts are able to tolerate extremely high temperatures and to acclimate to seasonal increases in temperature. In this study, ...
