The combustion of the alternative fuel, hydrogen gas, released 286 kj per mole of hydrogen gas combusted. if 10.0 l of hydrogen gas at STP was burned to produce electricity, how long would it power a 100 watt light bulb. assume no energy is lost t
Calculate (a). the kilograms of water per minute needed to remove the sulfur dioxide assuming that the exit water is in equilibrium with the entering gas and (b) the ratio of the water stream to the gas stream. The Henry's law constant for sulfur
Why are the bond angles of methane, ammonia, and water different for each even though the electron domain geometry is the same for each
Sodium azdide, NaN3, decomposes according to the following equation. What volume of N2 at 1.1 atm and 50.0C will be produced by the decomposition of 5.0g of sodium azdide. NaN3(s) --->Na(s)+N2(g)
Calculate the values of k and kc for the reaction 3N2(g)+H2(g)<----->2NH3(g) at 25 c and 100c.
The broad features of the spectrum are thereforeexpected to resemble those of hydrogen, the differences arising largely from the mass relations. At which energy will the first three lines of the Balmer series of positronium appear?
