This is a video about the energy changes involved in chemical reactions, whether exothermic or endothermic. When exothermic reactions transfer energy to the surroundings, the temperature of the ...

In contrast to conventional organic synthesis, mechanochemistry does not use solvents that eventually become industrial ...

In this video, Fran Scott demonstrates how to measure the rate of reaction and how to increase it. The greater the frequency of successful collisions between reactant particles, the greater the ...

If they collide with enough energy, bonds can break and new bonds can form in a chemical reaction. The reactants just sit there until energy is added with the flame. The added energy is enough to make ...

E. H. Bawn and G. Ogden. Compare the reaction of a free hydrogen and a diplogen atom ; in the initial state the atoms possess no zero point energy and their energies will be equal. However ...

The U.S. Federal Reserve on Wednesday chose to hold interest rates steady, as widely expected, and signaled that it was in no ...

Hydrogen peroxide decomposes on its own into water and oxygen gas. This process is sped up by a catalyst. In this reaction, the catalyst is potassium permanganate, and the bubbles are full of oxygen ...

A new theory predicts one of the effects of macroscopic mechanical forces on mechanochemical organic synthesis by a ball mill. (left) Example of a ...

Identical concentrations of solutions A and B at three different temperatures (hot, room, and cold) are mixed. The different lengths of time needed to achieve the starch/iodine complex shows the ...
