Given equilibrium pressure, calculate Kp
When heated, ammonium carbonate decomposes as follows.
NH4CO2NH2(s) f/r2NH3(g)+CO2(g)
At a certain temp, the equilibrium pressure of the system is 0.318 atm. Calculate Kp for the reaction.
How many molecules of carbon dioxide are produced when 130 molecules of acetylene (HCCH) to react in excess oxygen produce carbon dioxide and water.
In a calorimeter, 100 g of ice melts at 0oC. The enthalpy of fusion of the ice is 334 J/g. How much heat was absorbed.
These 3 solutions including 2.362 g of Rb2S, 1.635 g of NaClO 4 , and 0.796 g of CuCl 2 , respectively are combined together? now calculate what would be the mass of this precipitae?
