If 3.7 g of butanoic acid, C4H8O2, is dissolved in enough water to make 1.0 L of solution, what is the resulting pH?
a mixture of nitrogen and hydrogen reacts as fully as possible to form a 56 l mixture of ammonia and hydrogen at stp. when this mixture is compressed to 10.0 atm and chilled to 200.0 K, all of the ammonia is liquefied leaving 3.2 L of hydrogen sti..
The Haber process is used in industry to produce ammonia from N2 and H2. A reactor contains NH3, N2, and H2 at equilibrium at 1000 K. The concentration of NH3 is 0.102 moles/liter, N2 is 1.03 moles/liter, and H2 is 1.62 moles/liter. Calculate the ..
