Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!
You will do much better asking your Chemistry questions on a Chemistry homework help site as opposed to an Algebra homework help site. Just like you will have an easier time of it if you go to the grocery store instead of the hardware store to buy a loaf of bread. Also, putting a time requirement on volunteer (read unpaid) tutors and ignoring the rules for posting are both indicators of an overabundance of arrogance on your part. Just sayin'
