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?
