3x^2-5X-2=0 that is the problem so i did this i dont know if its right
3X(3X^2 - 6X) 1(1X-2)
(x-2) (X-2)
I dont think this is right because i thought one had to be positive and one negative ...i may be wrong i was just wondering if someone could help me.. thanks

I need help on how to get started with a homework problem. Here is the problem:

Temperature of hot air = 100 degrees celsius
Temperature of cold air = 0 degress celsius
Volum of water pulled into the flask(mL) = 214 mL
Maximum volume of water the flask will hold (mL) = 300 mL

What is the volume of air in the flask at the hot temperature?
What is the volume of air in the flask at the cold temperature?

I have looked in my school book but there is no information on how to do this. If someone could help me get started with this problem, it will be greatly appreciated. You do not need to do the problem for me, just tell me what I need to do. THANKS!!!

okay im asked to arrange compounds that were tested in order by increasing extinction coefficients. There is only 2, 2.263 for CuSO4 and 3.326 for CoCl2.

Now it says to discuss what this order means in terms of ability of these substances to absorb light. Here is what I got from wiki:

The extinction coefficient for a particular substance is a measure of how well it absorbs electromagnetic radiation (EM waves). If the EM wave can pass through very easily, the material has a low extinction coefficient. Conversely, if the radiation hardly penetrates the material, but rather quickly becomes "extinct" within it, the extinction coefficient is high.

So I guess that would mean that the higher the extiction coeffcient the better the ability to absorb light?
