Question Solved1 Answer I do not want to explain by writing, calculations help me to understant better. The thermite reaction involves aluminum and iron(III) oxide 2Al(s) +Fe2O3(s) -Al2O3(s)+2Fe(1) This reaction is highly exothermic and the liquid iron formed is used to weld metals. > Calculate the heat released in kilojoules per gram of Al reacted with Fe2O3. The AH in kJ/ mol for Fe(/) is 12.40, Al2O3 -1669.8, and Fe203 - 822.2.

2) Create a maths problem and model solution corresponding to the following question: "Find the directional derivative of the following two-variable function for the supplied point and unit vector" Evaluate the directional derivative at the point (2, 5). Ensure that your supplied function uses both x and y, has 3 terms, and that at least one of those terms 2) Create a maths problem and model solution corresponding to the following question: "Find the directional derivative of the following two-variable function for the supplied point and unit vector" Evaluate the directional derivative at the point (2, 5). Ensure that your supplied function uses both x and y, has 3 terms, and that at least one of those terms contains √x. You may choose the vector representing the direction you will evaluate the directional derivative in, and the derivative must be a multiple of √2.

Answer the following in 100 words(each). “Because debt interest lowers a company’s tax bill, companies should always try to borrow as much as possible”. Say whether you agree or disagree and explain why. “The cost of debt for a company is always lower than the cost of equity. For this reason, a company should always finance new projects with debt”. Say whether you agree or disagree and explain why. Explain why standard methods of calculating the NPV of a project do not capture the value of ‘real options’. “Companies whose assets have low betas have low costs of capital and this gives them a competitive advantage in takeover battles since they will place a higher value on the assets of takeover targets than companies with high beta assets”. Say whether you agree or disagree and explain why. “A company’s lenders and its shareholders can sometimes disagree about the investments that the company should make. Keeping leveraging low helps to keep these disagreements to a minimum”. Say whether you agree or disagree and explain why.
