A mixture of 3.78 moles of N2 and 3.78 moles of O2 is placed in a 1.00 L container at 448 °C and allowed to reach equilibrium according to the following equation.
N2(g) + O2(g) ? 2NO(g)
The equilibrium constant is 100. Calculate the concentrations of O2 present at equilibrium.
Copper metal and zinc metal react differently in the presence of certain acids. For example, while both react with concentrated nitric acid and dissolve completely, only zinc reacts and dissolves in dilute hydrochloric acid.
