How is an element different than a compound?
While elements and compounds are both pure substances elements are only made of one kinds of atom while compounds are composed of two or more atoms.
Zinc hydrogen carbonate
ZnHCO3
mixture of two compounds
two types of compounds present
What is a compound? Two examples
A compound is a pure substance composed of two or more elements that are chemically combined. Compounds have a specific ratio. EX water (hydrogen and oxygen) and salt (sodium chloride)
What is a mixture? (remember two types-heterogenous and homogenous) two examples of each.
A mixture is composed of two or more substances physically combined. A mixture has no specific ratio. *** Heterogeneous mixtures look different throughout, you can see individual parts and the mixture may settle upon standing EX trail mix and milk. *** Homogeneous mixtures look the same throughout, you cannot see differences, are also called solutions EX: lemonade and air
