Ammonium is formed from Nitrogen(g) and Hydrogen(g). At 200 degree N(g) =2.0 atm , H(g) gas are transferred in sealed container.
At equilibrium, Ptotal(total Partial Pressure) = 2.0 atm. Calculate Kp.
Please solve it step by step. I am struggling to understand how to solve it.

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
