Pure vs. Mixture
Label which of the following is a pure substance and which are mixtures:
Solubility
Define the following vocab words:
Solubility is ____________________________________________________________________

Circle, in each example, which substance is the solvent and underline which substances are the solutes:
Coffee + Water + Sugar + Milk = Latte
Chicken Broth + Carrots + Chicken + Pasta = Chicken Soup
Water + Syrup + CO2 gas = Soda

_________________________ __________________________ ________________________
How does chromatography separate solutes?
___________________________________________________________________
_________________________________________________
How would salt affect the temperature of boiling water? _______________________________
If Water and Ethanol are mixed the solutions’ mass (increases/decreases/stays constant) and its volume
(increases/decreases/stays constant).

14. What is the atomic number of Manganese? _________
15. Who do you think element number 99 is named after? _______________________________________
16. A compound is made of two or more elements joined together. The subscript (small number) written after
each element symbol represents the number of atoms that are present in each molecule of that compound. If
no number is written after the element symbol then you can assume that only one atom is needed. List the
names of the elements in each of the following compounds and the number of atoms present in each
molecule.
a. Water: H2O ____________________________________________________________________
b. Table salt: NaCl ________________________________________________________________
c. Baking soda: NaHCO3 ___________________________________________________________
d. Table sugar: C12H22O11 ___________________________________________________________
