Help with my dimensional analysis homework in chemistry?

You are not done. That appears to be the number of km per second. I do not see the conversion from 100 km to?

Miles.It should be 100 km = X miles, and then X / 3600 = miles per second. I hope this helps .

The key to dimensional analysis is to always put the units on the fractions used in the conversions. If your conversion ratios are right, and your units all cancel out, you should be left with the right dimensions and the right answer.100 km/hr * 1.6 mi/km * 60 min/hr * 60 sec/minRemember that they call them dimensional "units" for a reason; each equivalence is equal to a unit, or 1, so you're multiplying the original by 1*1*1 to get the units to change. 1.6 km=1 mi, so 1.6 km/1 mi = 1.

If you leave ones on the conversion it can make it clearer. Do your problem again with the above and see what you come up with.

You hopefully notice I threw a curve in my answer so that you have to adjust it for the units to come out right. Can't do all the work for you, defeats the role of the teacher. :-) .

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
