Bubbles – Many chemical reactions you see in the science lab make a chemical which is a gas, so you see bubbles. A colour change – If the new chemicals are a different colour from the original ...

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.

When chemists design new chemical reactions, one useful piece of information involves the reaction's transition state—the ...

Did you know that a really fast chemical reaction makes riding in a car safer ... Instead of transporting compressed gas in the car to inflate the airbag, we take advantage of a very fast reaction ...

means there are so many collisions that the gas comes to chemical equilibrium very quickly. Similarly, very high-altitude flight (above about 70 km) has so few collisions that essentially no chemical ...
