At 273 K and 1.00*10^-2 atm the density of a gas is 1.24*10^-5 g/cm^3 a) find Vrms for the gas molecules b)find the moloculer weight of the gas and identify it.
calculate the theoretical yield percentage of a reaction between sodium and water if 25.0 g of sodium react with excess
determine the amount of heat energy is needed to raise the temperature of 0.362 kilograms of cu from 23. degree celsius
What product or products would you expect to obtain by the addition of bromine to cis-cinnamic acid, assuming that it reacts by the same mechanism as the trans acid
Suppose that coal of density 1.5 g/cm3 is pure carbon. (It is, in fact, much more complicated, but this is a reasonable first approximation.)
What is the pH after 0.150mol of HCL is added to the buffer from part A? Assume no volume change on the addition of the acid.
Suppose Joule encountered the waterfall at Niagara Falls. Calculate the height if the temperature difference between the top and bottom of the waterfall is 0.20° F.
For a particular reaction it was found that the reaction rate was 16 times faster at 35oC than it was at 25oC. It was also found that the equilibrium constant at 25oC was four times bigger than it was at 35oC.
Although the mechanism of the coupling process is not well understood, it is known that ratre appears to depend on the square of the concentration of the halide.
What volume in mL of concentrated nitric acid (72.0% HNO3 (w/w), sp. gr. 1.42) is required to prepare exactly 3.85 L of 0.330 M HNO3?
Write the overall equation for the reaction. B) Do you expect this reaction to go by an E1 or an E2 mechanism?
Which of the following substances would be most efficient per unit mass at melting snow from sidewalks and roads: glucose, sodium chloride, ethylene glycol, or calcium nitrate. Your explanation should include possible environmental impact.
