This question came to mind as I was studying for an exam, and I looked at Occam's razor for what seemed like the hundredth time.

I've been told of entropy and Occam's razor numerous times, but no one's ever explained both of them in the same thought. At first glance, they seem to be in conflict with one another. What are your thoughts on it?

The 1994 Winter Olympics included the aerials competition in skiing. In this event skiers speed down a ramp that slopes sharply upward at the end. The sharp upward slope launches them into the air, where they perform acrobatic maneuvers. In the women's competition, the end of a typical launch ramp is directed 61° above the horizontal. With this launch angle, a skier attains a height of 15 m above the end of the ramp. What is the skier's launch speed?

5.00 mL of concentrated HCL is diluted to give 25.0 mL of 1.60 M HCL. What was the molarity of the concentrated HCL?

The answer is 8.00 M.

The formula is Mi=Mv (i and v are subscripts) but I dont understand how to use it.

If I am determining the chemical formula of an ionic compound containing two moles of iron and three moles of sulfate ions per mole of the compound

I understand it would be set up as
2 moles Fe 2 Fe atoms
_______________ ___________
1 mole compound 1 formula unit

and

3 moles sulfate 3 sulfate ions
____________ ____________
1 mole compound 1 formula unit

What I don't understand is why the chemical formula is
Fe2(SO4)3 ... why isn't it Fe2S3?
Can someone please explain it to me... and why it is Fe2(SO4)3.

I get the logic of "springing forward" (sports can go longer into the night, better for retail, arguably better for energy usage) but why not stick to that time all year? Why does it need to become dark at 4 rather than 5 in northern locales? I've always thought this sucks. What's the advantage of the winter "fall back"?
