implements the suggested methodology‚ what would be the range of discount rates that AES would use around the world? If Venerus and AES implement the suggested methodology‚ the projects would change while WACC changes. To find WACC we must first calculate the leveraged bets for each the US Red Oak and Lal Plr Pakistan projects‚ using the equation unleveled beta/(1-D/V). It is easy to find debt to capital ratios‚ which are 39.5% for U.S and 35.1% for Pakistan‚ and the unleveled beta‚ which are both

EXPERIMENT 7: PERCENTAGE OF OXYGEN IN KClO3 Introduction: In this experiment you will determine the percentage of oxygen in potassium chlorate. You will calculate the theoretical value from the chemical formula and compare your experimental value to the theoretical value. Background: When potassium chlorate (KClO3) is heated‚ it undergoes chemical decomposition. Oxygen gas (O2) is given off and potassium chloride (KCl) remains as the residue. The equation for the decomposition of potassium
