if the equilibrium concentration of nitrogen at 18degrees C is 0.256M and equil. concen. of hydrogen is 0.0184M what is the equil. concen. of ammonia? N2 + 3 H2 2 NH3; so K= [NH3]^2 / [N2][H2]^3 Is this correct? Then ICE table? Giving me.... K= (2x)^2 /

How did the sun wind up in the middle of the solar system? Did the materials, gas and dust that eventually formed the planets come from the sun? Since our solar system is already formed, we must try to reconstruct its history by studying current star

An emf is induced in a conducting loop of wire 1.24 m long as its shape is changed from square to circular. Calculate the average magnitude of the induced emf if the change in shape occurs in 4.21 s, and the local 0.123 T magnetic field is perpendicular to
