CH49 – Recapping

Dates

• P4 – Wednesday, May 16th
• P5 – Thursday, May 17th
• P7 – Thursday, May 17th

Lab Recap – Calculations

• moles of gas (from Mg)
• volume of gas (L)
• pressure of the gas (subtract P of water)
• temp of gas (K)
• combined gas law – volume @ STP
• molar volume @ STP
• comparison to known

Class Business

• Lab Report expectations

New Idea – KMT (Section 5.7)

• T related to KE of particles
• KE = 1/2 mv2
• basic math… can compare “v” to “m”
• inverse square relationship
• diffusion and effiusion
• four times as heavy = half as fast

Moving Ahead

• Long Block = review & test
