A sample of 4.00 mL diethylether (C2H5OC2H5 ; density 0.7134 g/mL) is introduced into a 5.00 L vessel
that already contains a mixture of O2 (PO2 =0.208 atm)
and N2 (PN2 = 0.751 atm). The temperature is held at
35.0oC and the diethylether totally evaporates.
Calculate (a) the partial pressure of the diethylether;
and (b) the total pressure in the container.

The atomic radius of sodium is 186 pm and of chlorine is 100 pm. the ionic radius for na+ is 102 pm and for cl– is 181 pm. in going from na to cl in period 3, why does the atomic radius decrease while the ionic radius increases? a. the inner electrons in the sodium cation shield its valence electrons more effectively than the inner electrons in the chloride anion do. b. the inner electrons shield the valence electrons more effectively in the chlorine atom than in the chloride anion. c. the outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. d. the outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. e. monatomic ions are bigger than the atoms from which they are formed.

The three types is stress that act on earths rocks are compression, tension, and

Need what is special about water as a compound? how does water regulate climate? what drives water evaporation?   why is the water vapor fresh water when it rises from the ocean? why might freshwater in the form of snow take longer to enter the water cycle again than liquid precipitation?   what is an aquifer? what role do people play in the water cycle? plz just answer as many as you can ! thx if you !
