I'm planning a trip to the "land down under", and my mom started making jokes about stuff falling out of my pocket (because I'll be on the bottom of the globe) and such. This led to a discussion about why people DON'T fall off the bottom of the earth. I Googled it and found several scientific explanations, but I would like someone to explain it to me in simple layman's terms.

Thanks in advance.

Using tabulated standard reduction potentials from your text, calculate the standard cell potential, E°cell (always positive for a galvanic cell), based on the following (unbalanced) reaction:

IO3^- (aq) + Fe^2+(aq) <--> Fe^3+(aq) + I2(s)


Can someone please help me with this because I've been retrying it for soo long and I just can't get the right answer. Please anyone help me. Thanks soo much.

OK....So if someone went back in time to say....10,000 B.C. Well wouldn't that mean that 17,000 years ago the person that went back in time was already there? I mean think about it, how could you go back in time if you weren't even alive at that time? Does this mean that the past and future are already set?

I'm sorry if you guys don't get my question, it is a little confusing, but I thought it was very thought provoking, and fun to think about =) Thanks!

This is the second time I've posted this question. I've already received a good answer from the first time I posted. The problem is that I forgot to say that I only have like 2 minutes for the problem. Once again.... NO CALCULATORS are allowed.
The question is below and the answer I got before is also below to help out.


There is a boy who is standing at the center of a circular field that had a radius of 135 feet. He walks due north halfway to the circle. He then turns and walks due east half way to the circle. He turns again and walks due south half way to the circle. Finally he turns and walks due west half way to the circle. When he stops, how many feet is the boy from the center of the circle? Round the answer to the nearest foot.

I'm confused. I'm insulin resistant, but have been told to try Stevia. I looked it up, and supposedly it does not raise blood glucose levels, but rather lowers them because it stimulates insulin secretion. But I thought that one of the problems I was having (I have PCOS) is that the level of insulin in my blood is too high, therefore causing some wonky hormone reactions. Is there some sciency person out there who can tell me why Stevia is supposedly good for diabetics and other insulin challenged folks? Is it only good for diabetics but not insulin resistant people?

In the circulatory system of an osteichtyes (bony fish), the heart only pumps deoxygenated blood, so how does the heart get its oxygen? Or does it function without it? How does that work?

An unknown compound contains only carbon, hydrogen, and oxygen. Combustion analysis of the compound gives mass percents of 31.57% C and 5.30% H. The molar mass is determined by measuring the freezing point depression of an aqueous solution. A freezing point of -5.20°C is recorded for a solution made by dissolving 10.56 g of the compound in 25.0 g water. Determine the empirical formula, molar mass, and molecular formula of the compound. Assume that the compound is a nonelectrolyte.
