DO-NOW Volume 0 Use complete sentence and complete your Do Now in your comp book. Georgia was absent last week. Please write her a text explaining how to find density. Include the formula and the names of the tools you need.

Today’s Schedule 1. Do-Now 2. Finish Density Lab 3. Density Practice/Check 4. Microchemistry Objectives: Today we will… 6.6 (B) calculate density to identify an unknown substance 8.5 (E) investigate how evidence of chemical reactions indicate that new substances with different properties are formed Dark Matter

Take 5 minutes to finish your density lab. Voice Level 0 Take 5 minutes to finish your density lab. Please double check your calculations. Show all work. When you are done begin on the Density Practice.

Observing Chemical Reactions Chemical A Cobalt Nitrate Calcium Carbonate Sodium Bicarbonate Chemical B Ammonium Vannidate Na3PO4 H2O Acetic Acid Observations before and after.

Evidence of Chemical Reactions 1. 2. 3. 4.

Evidence of Chemical Reactions Gas formed (bubbles/odor) Color Change Heat absorbed or released (gets hot or cold) Precipitate formed (mix two liquids and solid forms) Evidence of chemical reactions indicates that new substances with different properties are formed.
