In this lab, you will study an enzyme that is found in the cells of many living tissues. The name of the enzyme is catalase; it speeds up a reaction which breaks down hydrogen peroxide, a toxic chemical, into 2 harmless substances--water and oxygen. Light can also break down H 2 O 2 which is why the chemical is sold in dark containers.
The periodic table may look complicated, but much of it comes down to one simple pattern: the transition from metal to nonmetal elements. The classic Periodic Table organizes the chemical elements according to the number of protons that each has in its atomic nucleus.
