When a reaction is in equilibrium, it means the rate of the forward reaction is equal to the rate of the backwards reaction. The concentrations of the reactants and products remain constant, but this does...

Metal + Acid --> Metal salt + H2 (g)E.g. Cu + HCl --> CuCl2 + H2

Answer= 0.144gWorking out:mol= conc x volume (in dm^3)mass = mol x RFFSo,mol = 0.18 x (20/1000) = 0.0036molMass= 0.036 x 40 = 0.144g

Okay so first always write out the equation...N₂(g) + 3H₂(g) ⇌ 2NH₃(g)Now we need to ask ourselves what equations we know are relevant to the question. The question gives ...

20/1000 *0.18
final answer 0.144 Answer must be explained in person. It is very difficult to explain in writing.
