A chemist must determine the coefficients x, (for 1 j 5) that balance the reaction Cu + xHNO3 23Cu(NO3)2 +

A chemist must determine the coefficients x, (for 1 j 5) that balance the reaction Cu + HNO3 23Cu(NO3)2 + xNO+x5HO. In order to balance this reaction, there must be an equal number of each element on both sides of the reaction. a. Use this information to derive a linear system satisfied by the unknown coefficients xj. Hint: Derive an equation that balances each element. b. What are the dimensions of this system? c. Is this system overdetermined, square, or underdetermined? Based on your answer, is it most likely this system has no solution, a unique solution, or infinitely many solutions? Exercise 2. (Component Skill 1.2) Express the linear system in Exercise 1 in matrix-vector form and as an augmented matrix.
