Lab: Reaction in a Bag

• Combine solid A and solid B with a red liquid in a paper bag to make a reaction.
• Reaction - Warm and cold, yellow, bubbly, bag inflates, solids dissolve, and a gas filled up the bag.

Chapter 1

1.1 Lab: Baking Soda

• When baking soda is heated it turns into a different substance.
• Heated baking soda in tea is a different color than non-heated baking soda in tea.
• Condensation formed near the top of the test tube.

1.2 Notes: Volume

• L x W x H
• Standard unit of length = Meter (m)
• 100 centimeters = 1 m
• Use a graduated cylinder to measure volume
• 1 mL = 1 cm^3

1.4 Lab: Measuring Volume by Displacement of Water

• (Sand + Water) - Water = Sand alone
• (Dry sand + Air) - Sand alone = Volume of air
• % of sand that is air = is/of = air/dry sand

1.8 Lab: The Sensitivity of a Balance

• 0.02 is the sensitivity of our balances.

Chapter 2

2.1 Lab: The Mass of Dissolved Salt

• When adding salt into water, the mass decreases.

2.4 Lab: The Mass of Ice and Water

• Condensation easily forms

2.5 Lab: The Mass of Copper and Sulfur

• Condensation, white-yellow gas, bubbles, black liquid that turned clear, and a new black solid after the reaction.

2.6 Lab: Mass of a Gas

• There should be no change in mass.

Chapter 3

3.2 Lab: Mass and Volume

• Objects made of the same substance and have the same volume, will have the same mass.
• Objects made of different substances, but have the same volume, will not have the same mass.

3.5 Lab: The Density of Solids

3.6 Lab: The Density of Liquids

3.7 Lab: The Density of a Gas
