Molecular Geometry / Polarity Practice

Tutorial on polar vs. nonpolar

Polar vs. Nonpolar Practice Problems  (with Ionic!)

As for practice problems thinking about molecules in 3D - go to the applet to the right and look at the "real" molecules.  Try to build them using only the formula and then click on them to see if you were correct

Project 1 EXAM - Wednesday October 21st

Here is some extra practice

Atomic Structure 


Unit Conversion


SigFigs Practice Problems


Ionic and Covalent Naming - Use your Polyatomic Ion Sheet


EM Radiation Practice

Biochemistry Exam - Material to be Assessed

Here is the content that will be covered on this exam:

• Atomic Structure
• Protons, Neutrons and Electrons (symbols, location, charge)
• Isotopes
• Periodic Table (avg atomic mass, atomic number)
• Ions
• Cations and their charges (groups 1, 2 and 3 only)
• Anions and their charges (groups 15, 16 and 17)
• Naming Ionic Compounds
• Monatomic Ions (i.e, NaCl)
• Polyatomic Ions (i.e. NaNO3) **can't subscript on blogspot, my apologies)
• Naming Covalent Molecules
• Binary molecules use prefixes (CO vs CO2) ** 
• EM Radiation
• EM Spectrum
• Higher vs Lower Energy
• speed of light  = wavelength x frequency
• Relationship between wavelength, frequency and energy
• Energy of Photons
• E = h x V
• Calculating Energy to compare to EM Spectrum
• Experimental Design
• Hypothesis 
• Representing Data
• Using Data to Draw Conclusions
• Constants vs. Variables vs. Controls
• Precision vs. Accuracy
• Precision in the equipment
• Precision in the form of repeatable data/results
• Accuracy comparing you results to known, accepted values
• Significant figures
• Number of Sigfigs in a given measurement
• Sigfig rules for zeroes
• Rounding to correct sigfigs during calculations

Significant Figures and Rounding Resources

Here are a few websites that reiterate the work done last class and what we will continue to do in the next day or two

Lab Write-Up: DIY vs. Store Bought Sunscreen

This lab is due at the end of the day on FRIDAY OCTOBER 9th.  If you get me a copy of your lab by TUESDAY OCTOBER 6th, I will give you feedback.  See the description of the write-up below.
