The molal freezing point constant for copper is 23 °C/m. If pure copper melts at 1083°C, what will be the melting point of a brass made of 33.1 mass percent Zn and the remainder Cu?
Carbon monoxide and water vapor, each at 200. Torr, were introduced into a container of volume 0.250 L. When the mixture reached equilibrium at 700 degrees Celsius, the partial pressure of CO2(g) was 88 Torr. Calculate the value of K for the equilibrium CO (g) + H2O (g)⇋ CO2(g)+H2(g).
