Consider the following chemical reaction: 2NH3 → N2 + 3H2 It was found that the rate of production of hydrogen, H2, is 0.39 mol L-1 S-1. What is the rate of decomposition of ammonia?

From their positions in the periodic table, arrange the atoms in each of the following series in order of increasing electronegativity:  Ba, H, N, O, As

Eric’s car, which weighs 1000 kg, is out of gas. Eric is trying to push the car to a gas station, and he makes the car move at 0.06 m/s2. Can you calculate how much force Eric is applying to the car? (Ignore the friction)

Suppose an oxygen tank has a pressure of 120 atm at a temperature of 25°C. If the temperature increases to 31°C, what will the final pressure of the oxygen tank be if the volume and amount of the oxygen are held constant?

There are three risky assets in your optimal risky asset portfolio:     Exp. Ret. Std. Dev. Wts in optimal portfolio                      Correlation Stock Fund Bond Fund Comm.
