Chemistry is a big problem when you have a teacher who won't teach
PLEASE help

1. How many molecules are in one mole of: glucose; C(6)H(12)O(6)?
2. Calculate the mass of one mole of: glucose; C(6)H(12)O(6)?
3. How many atoms are in one molecule of: glucose; C(6)H(12)O(6)?

all I know is that she wants us to use the conversion
1 mole = 6.0221367x10(23) molecules

I've been struggling with this for TOO long and my friends and parents are no help
any help or answers you can give me is great thanks

I just want to make it clear that I am NOT a creationist. I'm a theistic evolutionist and am just genuinely curious about what a good response should be. I want to be able to argue FOR evolution in an effective way.

Creationists use the following examples to prove that evolution is false: http://www.creation-museum.net/fossils/index.php

Hare Krishnas also make a number of claims about archaeological "cover-ups". What do you make of them?:

http://www.forbiddenarcheology.com/ (This website makes weird claims about modern man-made objects being found in millions of year old rock)
http://krishnascience.com/6_Coverups_1.html

Please try to have at least a brief look at the websites, because it is this type of claims that I'm interested in an explanation for.

This is a question for evolutionists, NOT creationists, so please don't reply with "Evolution is false" or "That ain't true, coz the Bible done say so..." I'm not interested.

The equation (x-1)^2+(y-2)^2+(z-3)^2=9 represents a sphere in 3D space. Find the equation in the form of Ax+By+Cz+D=0 of the plance that is tangent to the sphere at (2,4,5), a point at one end of the diameter of the sphere.

Can someone please explain to me in detail, i've not learn how to solve this in class.

Thanks.

Oh and also,
How do you find the equation of the sphere whith centre (2,1,3) and tangent to the plane 3x-4y+2z=12.

Im really confused that this point, but i managed to start the question and am stuck now.
