2nh_3(g) \longleftrightarrow n_2(g) + 3h_2(g) \hspace{30pt} k_p = 0.83 2 n h 3 ( g ) ⟷ n 2 ( g ) + 3 h 2 ( g ) k p = 0.83 consider your answers above, if the initial pressures for all three species is 1 atm what is the equilibrium pressure of h2? (hint: your quadratic will have two solutions, which one is impossible? )

What is important to study for nios grade 12 chemistry? i have only one month left.

Hot air balloons float in the air because of the difference in density between cold and hot air. in this problem, you will estimate the minimum temperature the gas inside the balloon needs to be, for it to take off. to do this, use the following variables and make these assumptions: the combined weight of the pilot basket together with that of the balloon fabric and other equipment is w. the volume of the hot air inside the balloon when it is inflated is v. the absolute temperature of the hot air at the bottom of the balloon is th (where th> tc). the absolute temperature of the cold air outside the balloon is tc and its density is ďc. the balloon is open at the bottom, so that the pressure inside and outside the balloon is the same. as always, treat air as an ideal gas. use g for the magnitude of the acceleration due to gravity.

Asample of ammonia reacts with oxygen as shown. 4nh3(g) + 5o2(g) 4no(g) + 6h2o(g) what is the limiting reactant if 4.0 g of nh3 react with 8.0 g of oxygen? o2 because it produces only 0.20 mol of no. nh3 because it produces only 0.20 mol of no. o2 because it produces two times less no than nh3. nh3 because it produces three times more no than o2.
