Problem- What is the pH of the resulting solution if 45 mL of 0.432 M methylamine, CH3NH2, is added to 15 mL of 0.234 M HCl? Assume that the volumes of the solutions are additive. Ka = 2.70 Ã? 10-11 for CH3NH3+.
I just need a general explanation of it please- Thanks!
Explain how long will the system produce 15.00 amperes of current and what is the Grxn for this reaction if the resistance is 0.08750 ohms. The Faraday constant is 96485.3C/mole of electrons; V=I*R, the reduction reaction of O2 is O2 + 4H+ + 4e-->..
Solid iron reacts with chlorine gas to produce iron(III) chloride. If 10.0 grams of iron reacts with excess chlorine gas and 18.5 grams of iron(III) chloride is produced, what is the percent yield of the iron(III) chloride
