Calculate the moment of inertia, I, of the molecule 1H35C when the masses of the two atoms are m = 1.673 x 10^27 kg and mci = 5.807 x 10^26 kg. The equilibrium bond length of the molecule is 1.275 Ã…. 2. Corrected_text: Calculate the bond length of the OH molecule in the gas phase if the first two lines of the microwave spectrum occur at 8.562 cm^-1 and 17.124 cm^-1. 3. Corrected_text: A reaction 5A-P has a fifth-order rate law. Write the rate law expression and derive an equation for the time required for the concentration of A to change into P. 4. Corrected_text: A second-order reaction of the type A + 2B -> P was carried out in a solution that was initially 0.085 mol.dm^-3 in A and 0.160 mol.dm^-3 in B. After some time, the concentration of A had fallen to 0.065 mol.dm^-3 with a rate constant of 0.000023 dm^3.mol^-1.s^-1. Calculate the time h required for the concentration of A to change from 0.085 mol.dm^-3 to 0.065 mol.dm^-3.

Please answer ASAP 1. An individual has $25,000 invested in a stock with a beta of 0.3 and another $45,000 invested in a stock with a beta of 1.4. If these are the only two investments in her portfolio, what is her portfolio's beta? Do not round intermediate calculations. Round your answer to two decimal places. 2. Assume that the risk-free rate is 5% and the required return on the market is 11%. What is the required rate of return on a stock with a beta of 2.3? Round your answer to two decimal places. 3. Assume that the risk-free rate is 4% and the market risk premium is 4%. What is the required return for the overall stock market? Round your answer to two decimal places. What is the required rate of return on a stock with a beta of 0.6? Round your answer to two decimal places. 4. Calculate the required rate of return for Mudd Enterprises assuming that investors expect a 4.2% rate of inflation in the future. The real risk-free rate is 3.0%, and the market risk premium is 6.0%. Mudd has a beta of 1.2, and its realized rate of return has averaged 15.0% over the past 5 years. Round your answer to two decimal places.
