Determination of molecular SO2 needed
"You have just finished fermenting a wine and the pH = 3.7. You need 2mg/L "molecular" SO2 to protect the wine. What level of free SO2 do you have to add to achieve the level of the molecular form desired? You can ignore the sulfite(SO3) form at this pH as the levels will be negligible. Perform by calculation and give answ ...continues
I don't understand what Mass Spectrometry is. All the websites and books I have been looking in are too difficult to understand. Can you Give me a description of what it is and what it is used for. I need to write a three page paper on it and I don't want to plagerize, but I don't understand the concepts. "Mass spectrometr ...continues
please show me how to balance this equation using oxidation half reaction and reduction half reaction FecL2+kMnO4 +HCl---------->FeCl3+KCl+MnCl2+H20
What is the molarity of a K2SO3 solution if 25.0ml of it was oxidized by 30.0ml of 0.450M KMnO4 aqueous solution? Molarity=moles of solution /liters of solution Where do I go from here?
How do I calculate the moles of iron (ore sample) and how do I calculate the mass percent of iron in the ore from this problem; Ferrous ion reacts with permanganate ion Mno4 in acidic solution to produce the ferric ion fe3. A6.893 gram sample of ore was mechanically crushed and then treated with Hcl which oxidized all the i ...continues

Describe the patterns in the electronic configurations of the elements. Each row across the periodic table is called a period and the elements gradually change properties from left to right. Can you explain this in terms of the electronic configurations? Each column of the periodic table is called a family. Elements in t ...continues
