The competition primarily judges the accuracy of the chemical reaction for stopping the car more so than speed or power. Given that the load the car must carry is typically unknown until the day ...

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 ...

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 ...

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.

A chemical reaction that's vital to a range of commercial and industrial goods may soon be initiated more effectively and less expensively. A chemical reaction that's vital to a range of ...

A biochemical reaction is the transformation of one molecule ... which are biological catalysts that can alter the rate and specificity of chemical reactions inside cells. In this Perspective ...
