A nov At a certain temperature the vapor pressure of pure diethyl ether (C4H10O) is measured to be 0.7 atm. Suppose a solution is prepared by mixing 50.0 g of diethyl ether and 50.0 g of chloroform (CHCl3). Calculate the partial pressure of diethyl ether vapor above this solution. You may assume the solution is ideal. Molar mass C4H10O

If 1.8 l of water is added to 2.5l of a 7.0 m koh solution, what is the molarity of the new solution

What is the wavelength of a 3*10^12 hz infrared wave a 3*10^20m b 1* 10^4m c 3*10^-3m d 1*10^-4 m

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
