• Questions? Comments?

New Material – Virtual Lab

• iPad app = virtualBrowser
• Use this to go to the virtual lab web site [LINK]
• Go to: Stoichiometry > Reaction Stoichiometry and Limiting Reagents > Determining Stoichiometric Coefficients [LINK]
• Complete the Activity

Notes on Virtual Lab

• works perfectly on a laptop or desktop computer
• on the iPad make sure you have a stylus
• while in iPad, you will need to be patient with the time lags in the application
• concentrations are shown in scientific notation (1e-1 means 0.1M)

Homework

• complete the Oracle Problem (loaded in the File > Homework menu)
• to move the pieces on the lab you will need to double click and hold

New Material – Precipitation Reactions

• double displacement reactions
• how do we predict what forms?
• solubility rules: page 156 (Ch. 4)
• writing reactions: molecular, full ionic, net ionic
• examples

Homework

• Prep the lab for the “Precipitate Lab” (LNB)
• Purpose, Procedure, Data sections only
• there will not be a formal lab report for this (no calculations, analysis, conclusion)
