INTRODUCTION For this experiment we studied an oxidation-reduction reaction of magnesium and hydrochloric acid solution. We compared the experimental measured amount of a product and the amount predicted by the theoretical calculation of a balanced equation: Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g) PROCEDURE First we obtained a strip of pre-cut magnesium ribbon‚ cleaned it with steel wool to remove any signs of oxidation from the strip (which would alter our results)‚ and then weighed it (individual

Assignment questions 1. What is the WACC and why is it important to estimate a firm’s cost of capital? Do you agree with Joanna Cohen’s WACC calculation? Why or why not? WACC means the weighted average cost of capital. WACC is based on the respective weights of the firm’s financing sources‚ equity and debt at the respective return rates. A firm’s capital comes from two main ways

assumptions implicit in Bill French’s determination of his company’s breakeven point? There are a number of simplifying assumptions made by Bill French in his calculations of the breakeven point of his company‚ Duo – Products Corporation. First‚ he had assumed that the market conditions will remain the same. Second‚ his calculations are based on the last year prices; it does not take into account in any change in prices. Third‚ he also ignores any changes in the fixed and variable costs of the

2. Let us assume two students must prepare a presentation for their marketing class. As part of their class presentation‚ they must do a series of calculations and prepare 50 PowerPoint slides. It would take Larry 10 hours to do the required calculation and 10 hours to prepare the slides. It would take Kate 12 hours to do the series of the calculations and 20 hours to prepare the PPT slides. A. How much time would it take the two students to complete the project if they divide the two tasks equally

the only service performed is the giving of haircuts‚ the unit price of which is $12. Andre has asked you to find the following information. 1. Find the contribution margin per haircut. Assume that the barbers’ compensation is a fixed cost. Show calculations to support your answer. Contribution margin is the marginal income per unit sold. The formula is the per unit sales price minus the variable cost per unit. For Andre‚ with a sales price of $12.00 and a variable cost of $0.40 per cut‚ his Contribution

Purpose: To determine the most powerful group in carrying someone upstairs. Background Information: A force is a push or pull on an object with the effect of the object’s interaction with another object. Forces only exist as a consequence of an interaction. To find the force of an object use the formula: F = m • a. Where F‚ stands for force‚ m stands for mass and a for acceleration. Displacement is how far away the endpoint is from the starting point in a straight line. Work is the means of transferring
