Conversion Factors/Equality Statements/Units

Ok, I don't expect this post to be very long. I just wanted to say, mainly due to the lesson yesterday, I can see why I will need to write my units and the equation out. The equations at chs I guess just weren't complicated enough for me to see why they warranted writing out. Now that there're so many more elements (pardon the pun) in the equations, it's clear that I'll need to be sure to write the units for everything so I can make sure they're actually cancelling out so I don't end up with answers in mol/g/sec/km. /new topic/ man, back to the names.. I really need to make sure I get these down this time. First quarter I was lost for the majority of it, and that made my grade fall apart. Now that it's back up to where I my mom won't out, i need to try to keep it somewhere around here. i think i mainly need to get the difference between nitrate and nitrite, along with some other stuff. maybe. hopefully.
