Determine the [H+], [OH], and the pH of a solution made by dissolving 1.03 g of NaOH, a strong base, in water to make exactly 1.50 liters of solution?
At 1000 K the equilibrium constant for the reaction Br2 (g) === 2 Br (g) is 2.8 x 104 (pressure is in atmospheres). What does G for the reaction. Assume that the bond energy of Br2 does not change between 298 K and 1000 K and calculate S for the r..
Ultra-high-vacuum experiments are routinely performed at a total pressure of 1.0 x 10-10 torr. Calculate the binary number of collisions, Z11, of N2 molecules (per liter per second) at 350 K under these conditions. The collision diameter of N2 is ..
