Suppose we want to make a 10 item queue starting from location x4000. In class, we discussed using a HEAD and a TAIL pointer to keep track of the beginning and end of the queue. In fact, we suggested that the HEAD pointer could point to the first element that we would remove from the queue and the TAIL pointer could point the last element that we have added the queue. It turns out that our suggestion does not work.

Part a) What is wrong with our suggestion? (Hint: how do we check if the queue is full? How do we check if it is empty?)

Part b) What simple change could be made to our queue to resolve this problem?

Part c) Using your correction, write a few instructions that check if the queue is full. Use R3 for the HEAD pointer and R4 for the TAIL pointer.

Part d) Using your correction, write a few instructions that check if the queue is empty. Again, using R3 for the HEAD pointer and R4 for the TAIL pointer.

Balancing Redox Equations in Acidic or Basic Solutions

In addition to mass balance, oxidation-reduction reactions must be balanced such that the number of electrons lost in the oxidation equals the number of electrons gained in the reduction. This balancing can be done by two methods. The oxidation number method balances the net increase in oxidation of the substance oxidized with the net decrease in the oxidation number of the substance reduced. The half-reaction method balances the electrons lost in the oxidation half-reaction with the electrons gained in the reduction half-reaction. In both methods

H2O(l),OH?(aq), and H+ (aq) may be added to complete the mass balance. Which substances are used depends on the reaction conditions.

Acidic solution

In acidic solution, bromate ion can be used to react with a number of metal ions. One such reaction is

BrO3?(aq)+Sn2+(aq)?Br?(aq)+Sn4+(aq)

Since this reaction takes place in acidic solution,

H2O(l)andH+(aq) will be involved in the reaction. Places for these species are indicated by the blanks in the following restatement of the equation:

BrO3?(aq)+Sn2+(aq)+ ____ ?Br?(aq)+Sn4+(aq)+ ___

Part A

What are the coefficients of the six species in the balanced equation above? Remember to include coefficients for

H2O(l)andH+(aq)

in the appropriate blanks.

Enter the equation coefficients in order separated by commas (e.g., 2,2,1,4,4,3).

     

Basic solution

Potassium permanganate,

KMnO4, is a powerful oxidizing agent. The products of a given redox reaction with the permanganate ion depend on the reaction conditions used. In basic solution, the following equation represents the reaction of this ion with a solution containing sodium sulfite:

MnO4?(aq)+SO32?(aq)?MnO2(s)+SO42?(aq)Since this reaction takes place in basic solution,H2O(l)andOH?(aq)

will be shown in the reaction. Places for these species are indicated by the blanks in the following restatement of the equation:

MnO4?(aq)+SO32?(aq)+ ____?MnO2(s)+SO42?(aq)+ ___

Part B

What are the coefficients of the six species in the balanced equation above? Remember to include coefficients for

H2O(l)andOH? (aq) in the blanks where appropriate.

Enter the equation coefficients in order separated by commas (e.g., 2,2,1,4,4,3).

A cart is attached to a hanging mass by a string that passes over a pulley. a) Draw free-body diagrams for the cart and the hanging mass (Clearly label all forces present and indicate their relative magnitudes) when the cart is moving:(i) on a horizontal track.(ii) up a track inclined at an angle .b) When the cart moves on an incline at constant speed, it is in equilibrium; i.e., the net force on it is zero. Does it require more, less, or the same tension in the string to pull the cart up the track at constant speed or down the track at constant speed? Explain your answer.c)Derive an equation for the work done by friction when the cart is moving up the track at constant speed. Show your work.

Here is a picture of a Binary Search Tree.



First, construct the Binary Search Tree using the following BinaryNode as we discussed in class.

public class BinaryNode {
        private int value;
        private BinaryNode leftChild;
        private BinaryNode rightChild;

        public BinaryNode(int value) {
                this.value = value;
                leftChild = null;
                rightChild = null;
        }

        public BinaryNode(int value, BinaryNode leftChild, BinaryNode rightChild)
        {
                this.value = value;
                this.leftChild = leftChild;
                this.rightChild = rightChild;
        }

        public int getValue() {
                return value;
        }

        public void setValue(int value) {
                this.value = value;
        }

        public BinaryNode getLeftChild() {
                return leftChild;
        }

        public void setLeftChild(BinaryNode leftChild) {
                this.leftChild = leftChild;
        }

        public BinaryNode getRightChild() {
                return rightChild;
        }

        public void setRightChild(BinaryNode rightChild) {
                this.rightChild = rightChild;
        }

        @Override
        public String toString() {
                return "BinaryNode: " +
                                "value=" + value;
        }
}

Second, print the nodes in level order, that is, the root node first, then the children of the root node, then the grand-children, etc. It is recommended that you accomplish this by using a queue to store the nodes, printing the first nodes that have been added to the queue.

Your program should print the following when it runs.

42 27 50 21 38 60 33 41 72

Submit the file LevelOrder.java when done.
