The seventh day was for worship and rest.
This to my mind is totally preposterous considering the science that says that it has more or less taken billions of years, even up to the date of the Bible writings.

Can there be two hydrogen bonds between two molecules of NH3? For instance, one of hyrdogen from one NH3 molecule bonds through hydrogen bonding with the nitrogen (N) of te second molecule. And then one of the hydrogens from the second molecule connects with the nitrogen atom of the first molecule. Is this possible? Why?


Thanks,
the Gibbler

Okay this is part of a lab question I need to answer. I'm really confused as to what the answer could be, but your help is much appreciated.

"To demonstrate the presence of catalase in living tissue, cut a 1-cm3 cube of potato or liver, macerate it, and transfer it into a 50mL glass beaker containing 10 mL of 1.5% H2O2. What would happen if you boiled the potato or liver before adding it to the H2O2?

I think the answer would be there would be no reaction, since enzymes do work in an optimum temperature. When I put the catalase on the potato that was not heated there was lots of bubbles and stuff, which I think was the oxygen that had been produced from the reaction. I think the heat of the potato or liver would denature the enzyme... but I'm not sure.

Ok, here's the question....

"Suppose that a bar 1m long expands 0.5cm when heated. By how much will a bar 100m of the same material expand when similarly heated?"

It seems like I would just multiply 0.5cm by 100. But this seems like too simple of a solution. Is this a trick question? If so, how do I do it correctly?

This, I think is the correct view, rather than saying that such and such view is a billion years in the past.
