A 3.33g sample of iron ore is transfered into a solution of iron(II) sulfate and this solution is titrated with 0.150M potassiumdichromate. If it requires 41.4mL of potassium dichromate solutionto titrate the FeSO4 solution, what is the precentage of iron inthe ore? The mole ratio between FeSO4 and K2Cr2O7 is 6:1. Answer +20.

The WACC is essentially a blend of the cost of equity and the after-tax cost of debt. The cost of equity is usually calculated using the capital asset pricing model (CAPM), which defines the cost of equity as follows: re = rf + β × (rm - rf) Where: rf = Risk-free rate. β = Beta (levered) (rm - rf) = Market risk premium.

Calcination is the process of converting ore into oxide by rapidly heating it. This method is frequently used to convert carbonates and hydroxides to their corresponding oxides. In the absence of air, carbonate ores are heated. In the absence of air and heat, CO 3 is converted into CO 2 and O. The metal retains the O as metal - oxide.
