1. ## Challenging Chem Problem

What mass of chromium metal can be produced in 1.00 h by the electrolysis of K2Cr2O7 solution using a current of 15.0 A? I know the answer is 4.85 g but how do you get that?
2. ## Independent/Dependent Variables

Do they necessary have to have quantitaitve values or can they sometimes be qualitative?? -Thanks
3. ## Geometry question

if an octagon is convex is it a regular polygon?
4. ## Ti-84 Silver Edition

i accidentally erased my memory and deleted all my orginal programs, those that came with it. is there a way to get them back without having to download them agian?
5. ## Explicit Formulas

How do you find the explicit formula of a degree higher then 4 using a matrix on the TI-83 calculator?

root(48) breaks down into 4rooot(3) and then u rationalize the denominator by multiplying root(3), so then a three falls out and u multiply the four by the three and u get 12 as the final denominator. u then multiply the numeratior by root 3, and u get 4+ root(18) ubut then u can then rationalize the numberator to 4+3 root(2)

What is: 4+root(6)/ root(48)? I got 4+3 root(2)/12 is that rite?
8. ## Molarity and Molality Problems

Can someone please explain to me how to do this problem. The molarity and molality of potassium chloride solution are 1.000 mol/L and 0.9750 mol/kg. what is the solutions density? I got an answer of 1.101 g/ml. will someone show me how to do it and verify to see if my answers right?
9. ## HCl and Mg Experiment

but if aird did enter into a sealed off eudiotmetr, then it would negativley affect the amount of h2 there would be.
10. ## HCl and Mg Experiment

i recently performed an experiment, with hcl and mg as i placed both into a eudiomter. how would air entering affect the way the reaction would occur?
11. ## HCl and Metal

so if you are looking for wether or not hcl is reactive with a metal, a change in color of the metal would not be something to look for?
12. ## HCl and Metal

Why when HCl reacts with a metal the metal changes colors.
13. ## Solubility Curves

Can someone expain to me how to interpret a solubility curve, how you know what temperture a solution is soluble, and how you know if a solution is super saturated based on the soulubility curve.
14. ## Imaginary Numbers

it would actually simplify to i^2n * i^3. but i mean as in simplify i, -1,-i , or 1
15. ## Imaginary Numbers

How would u simplify i^2n+3?????
16. ## Koch Curves

If the stage of a koch curve is at 0 and it has a length of 1, and a curve at a stage of 1 having a length of 1/3what would be the lengths of the curve at stages 2,3,and 4?
17. ## Absolute Zero

What would happen to the volume and pressure of the gas if it reached absolute zero?
18. ## Kelvin and Celcius

A temperture change of 1 K is equivalent to a change of how many degrees celcuis?
19. ## Square Root

have u ever heard of difference of perfect ssquares?
20. ## Square Root

Can someone explain to me why x^2=49, the value for x is plus or minus 7
21. ## Chemistry Problems

k thanks, that was the right answer when we checked in class
22. ## Chemistry Problems

A gas has a density of 2.857 g/l at STP. The pressure is dropped by 20.0 kpa in order to change its density to 2.000 g/l, what must be the new temperature to achieve this lower density. Any suggestions on how to start this problem is needed.
23. ## "Work" Word Problems

How do you do word problems involving "work" in them. Please, any help is appreciated.
24. ## Intermolecular Forces

I have a test tomorrow, and i have a question. Which intermolecualr forces are stronger liquids or gasses, and why. -thanks for any helps
25. ## States of Matter

so is it because in a solid, the nonpolar bonds are less dense compared to a liquid as the particles vibrate in place
