A sample of 5.0 L of diethyl ether (C2H5OC2H5, density = 0.7134 g/L) is introduced into a 6.00 L container that already contains a mixture of N2 and O2, whose partial pressures are PN2 = 0.751 atm and PO2 = 0.208 atm, respectively. The temperature is held at 35.0 °C. Calculate the partial pressure of the diethyl ether.
Calculate the total pressure in the container.

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

What do electromagnetic waves carry? how are they produced through which media can they move? where do they transfer energy? what do they not transfer? what do mechanical waves carry? how are they produced? through which media can they move? where do they transfer energy? what do they not transfer?

Hey, could someone me answer this? much appreciated!
