    How Do I Calculate the Molarity of Potassium Iodate in a Redox Titration?

    IO3- + 6H+ + 5I- = 3I2 + 3H2O I2 + 2S2O3 2- = 2I- + S4O6 2- You have to figure out the number of IO3(-)/S2O3(2-) Let me help you out here: For every IO3(-) 3 I2 are made and the relationship between them are 1/3 Okay. In the equation number 2, you have 1 I2 to 2 S2O3(2-). This...

    Lim((cosx/x^2)-(sinx)/x^3)) x->0 L'hopital

    Hey Everybody. I was just wondering about this query: lim((cosx/x^2)-(sinx)/x^3)) x->0 My teacher is telling me to use L'hopital, but the problem is that the first part (cosx)/(x^2) isn't a "0/0", cosx-> 1 for x->0 So what should I do, i know the right answer is -1/3, but i need...
