Ap Bio Help!

Postby mRxSodiuM » Thu Sep 07, 2006 6:46 am

I'm enrolled in an AP Bio class. I'm only a sophmore and I have never taken a Chemistry class so this course will be very difficult for me.

This is my first assignment: Write an essay about 5 chemical and physical properties of water that make it a suitable medium for life.

Here are my 5 properties of water:

1) it's a universal solvent (except for lipids)
2) can dissociate into hydroxide and hydronium
3) it's a polar molecule
4) its solid form is less dense than its liquid form (ice floats)
5) water has high specific heat

Water is also adhesive/cohesive, however, I have already listed 5. I want to know if these are appropriate/ acceptable properties of water for my essay. Which should remove and what else should I add?

Also, how can I go about to solve/approach this question to make a strong but concise essay?

Thank you for your time and help in advance! :D

well nothing of what u write is wrong. Water has one of the highest (the highest?) specific heat capacities. How much work are u going to spend writing this essay, are u going to explain what dipolar means and how it forms and why it has high heat capacity and so on? I think u have more then enough material.

Good luck

if i were you i would maybe change the third point for that adhesive property (because you've already mentioned what properties are connected with its polarity in the first 2 points).. but that's just my opinion;)
