Re: Sapling Week 5/6 #13

not only are there 4 hydrogen atoms, there are also 4 lone pairs between the nitrogen and the oxygen. these act as receptors of hydrogen atoms that are bonded to F, O, N. meaning there would be 8 possible hydrogen bond points

because they are created as molecules move around, and since the dipole that is created is not permanent that means it is easily broken

Re: How to remember what v is in equations

When i write them down I deliberately make v=frequency as like a cursive looking one and the velocity in my own handwriting. The best way to know is on the equation sheet is just to remember which equation uses which. Most of the time it will be for frequency, unless you're calculating momentum.
