• Changing Gases
• questions? comments?

New Idea – Gases and Stoichiometry

• gases are a part of chemical reactions
• examples: combustion
• can include volumes of gases as a part of calculations
• MUCH EASIER if the reaction is at STP

Practice: Ch. 5

• Easy: 65, 66
• Medium: 71
• Challenging: 75

Lab Day – Class 48

• Instructions in shared GDrive [LINK]
• Mg reacting with HCl
• capture gas produced
• experimentally determine the molar volume of a gas
• Tricky: water vapor
• Tricky: adjust from room conditions

Homework
