Ethanolamine, HOC2H4NH2, is a weak base. Its base-dissociation constant at 25°C is 3.2 ✕ 10−5. Calculate the pOH of a 0.474 M ethanolamine solution in water at 25°C.
Enhanced Binary Search Consider the binary search algorithm in Section 14.6. If no match is found, the search method returns -1. Modify the method so that if a is not found, the method returns -k - 1, where k is the position before which the element should be inserted. (This is the same behavior as Arrays.binarySearch.) Upload a file named BinarySearcher.java that has the same methods the binary search class in Section 14.6. Test Case 2 Test Case 1 Console...
