Lucite is 71.4% carbon, 9.59% hydrogen, and 19.01% oxygen. What is the empirical formula for Lucite?
C5H8O
C89HO31
C7HO2
The formula cannot be determined with only this information.
Catalysts are substances that increase the rate of reaction but can be recovered unchanged at the end of the reaction. Catalysts can be classified as either homogeneous or heterogeneous
