A direct current of 0.125 ampere was passed through 200 milliliters of a 0.25 molar solution of Fe2(SO4)3 between platinum electrodes for a period of 1.100 hours. Oxygen gas was produced at the anode. The only change at the cathode was a slight change in the color of the solution.

At the end of the electrolysis, the electrolyte was acidified with sulfuric acid and was titrated with an aqueous solution of potassium permanganate. The volume of the KMnO4 solution required to reach the end point was 24.65 milliliters.
a. How many faradays were passed through the solution?
b. Write a balanced half-reaction for the process that occurred at the cathode during the electrolysis.
c. Write a balanced net ionic equation for the reaction that occurred during the titration with potassium permanganate.
d. Calculate the molarity of the KMnO4 solution.

Or does it?

I'm wondering, because the Immigration section is getting REALLY bogged down in the hate lately (a latest "goodie" is people getting upset over "white girls" having immigrant boyfriends) to the point that it's almost scary. I'd really love to crunch some numbers and see if there's a religious correlation.

So.... what's your religion and do you have a problem with immigration (legal? illegal?) to your country?

Someone gave me a computer worm a link to http://ns1.hosting101.biz/~metalurg/images/template/index.php that automatically makes itself my homepage in Internet explorer..

Also my run command dissapeared from my start menu...

Yahoo messenger keeps automatically trying to email the virus link to my friends....

I've tried AVG, Spybot and Lavasoft, all found the virus but none do anything to fix it. deleting it or moving it to the "vault" doesn't work. Healing it doesn't work either!

I've done full scans also...

Help!

We just found a tic on my dog, and it was really big- like a big bump (you could hardly see it was a bug, just looked like a bump.) We got it completely off of him, but I am still very worried. I heard that tics can carry lyme disease. What should I do?

I live in Powhatan Va and my landlord has offerd to sell me the house I currently rent. The property is about 3.3 acres and the house is a 1950 cenderblock home. The house does need some work, but I see it as more of an investment. The offer is $127500.00 for the property and i KNOW it will increase in value do to its location. My wife and I have never bought a home and need advice about how to go about buying it directly from our landlord. We both work have good credit and little debt. Thanks so much for any help. :)
