Problem- When rubidium metal is exposed to air, two atoms of rubidium, Rb, combine with one atom of oxygen. If 1.75 grams of rubidium is exposed to air, what will be the mass of the product in grams?
It is not a question in the book, so I just need the full solution of deriving!
briefly explain how you will isolate p-tert-butylphenol after you have extracted it into NaOH solution.
A gas expands and does P-V work on the surroundings equal to 337 J. At the same time, it absorbs 177 J of heat from the surroundings. Calculate the change in energy of the gas.
How many grams of formic acid, HCOOH, must be added to 0.210 L of 0.160 M sodium formate, HCOONa, to yield a buffer solution with a pH of 4.10? Assume no volume change. Ka of HCOOH = 5.0 10-4.
what is the difference between oxy-mercuration, hydroboration, and acid hydrogenation
A cylinder, with a piston pressing down with a constant pressure, is filled with 2.10 moles of a gas (n1), and its volume is 50.0 L (v1). If 0.500 mole of gas leak out, and the pressure and temperature remain the same, what is the final volume of ..
