Metal hydrides are metal alloys that can store significant quantities of hydrogen in their atomic lattice. For this reason, they are considered potentially attractive for the on-board storage of hydrogen for hydrogen fuel cell vehicles. A certain metal hydride alloy can store 2 wt% hydrogen and has a density (including the hydrogen) of 12 g?cm3. Treating hydrogen as an ideal gas, what pressure would beneeded tocompressgaseous hydrogen tothesameequivalent concentration thatit attains when absorbed in the metal hydride?

Metal hydrides react with water to form hydrogen gas and the metal hydroxide. Use significant figures. SrH2(s) + 2 H2O(l) Sr(OH)2(s) + 2 H2(g) You wish to calculate the mass of hydrogen gas that can be prepared from 4.71 g of SrH2 and 4.26 g of H2O. (a) How many moles of H2 can be produced from the given mass of SrH2? (b) How many moles of H2 can be produced from the given mass of H2O? (c) Which is...

In the ground state of atomic hydrogen the electron can be pictured as existing some- where within a distance ∆x from the position of the nucleus with ∆x interpreted as the uncertainty in the position of the electron. (a) If ∆x is taken ot be the Bohr radius, calculate the uncertainty in the momentum of the electron. (b) If the uncertainty relation is written as rp = h(bar)?, the energy of the hydrogen atom can be expressed by E(p)=(p^2/2m)-(e^2p/h) Calculate...
