With any microscope or with any machine to be developed in the future - Can we see the neutrons? If it is possible can we see the atoms of glass? Generally more than 90% of light passes directly through a glass. Then very less light may redirect to our eyes through microscope. Can we watch the atoms or molecules of pure glass then?

I need help putting a specific program onto my calculator, I cannot for the life of me figure this one out. It doesn't just "send" like the other ones; so I assume it is an "assembly" program?

The program I want, is first on the list! http://www.ticalc.org/pub/83plus/asm/games/mirageos/rate.html

Hi
my chemistry teacher did an experiment that has something to do with the kinetic molecular theory. She burned a cylindiric piece of paper. As it was about to burned down, it just flew like 8 ft into the air. She expects me to know what happened and turn it in on Mon.

Can someone explain to me what happened?

PS: sry if i wasn't clear enough.

Ive worked this problem out, but it seriously doesnt make sense to me PLEASE HELP

When 1 mol Ca reacts with 1 mol water in the following reaction:
Ca +2H2O ----> Ca(OH)2 + H2

which reactant is limiting?
how much of the limiting reactant is left over in the previous reaction?

if 25.0 g of Ca reacts w/ 25.0 g of water what is the mass of calcium hydroxide formed in the formula used above? what is the mass of the excess reagent?

Sorry, i missed the lecture in class and ive treid to fig it out time and time again, please leave how to do the problem as well as the answer so i can learn as well. Thank you.

I can up with this rule, can somone please check to see if its right and then to write a proof for it?

Rule for y = f(x+k)
As the constant increases, the graph is moved farther to the left, and as the constant decreases the graph is moved farther to the right.

This is a school project, and i came up with this rule, can someone check this and then tell me how to prove this?

Rule for y = f(x) + k
The constant k controls the movement of the graph vertically, without modifying the shape of the graph meaning
