The standard emf for the cell using the overall cell reaction below is +2.20 V:
2Al(s) + 3I₂(s) →→ 2AI³⁺(aq) + 6I^-(aq)
The emf generated by the cell when [AI³⁺] = 3.5 × 10^-3 M and [I^-] = 0.30 M is ________ V.

Which of the following systems (i.e. pair of metals) would you expect to exhibit complete solid solubility? Explain your answers. (i) Cr-V (ii) Mg-Zn (iii) Al-Zr (iv) Ag-Au (v) Pb-Pt

Let T be an operator on a finite-dimensional complex vector space V, and suppose that dim Null T = 3, dimNullT2 =6. Prove that T does not have a square root; i.e. there does not exist any S ∈ L (V) such that S2 = T.

14. From the half-reactions below, calculate the solubility product of Mg(OH)₂.

          Mg²⁺ + 2e º Mg(s)                        E° = -2.360 V

          Mg(OH)₂(s) + 2e º Mg(s) + 2OH^- E° = -2.690 V

Find V(X) of the geometric distribution (Hint for the problem: Use the interchange derivative and summation, Find E(X^2), and then use the formula V(X) = E(X^2) - E(X)^2). Please show all work and all steps.

Cost can be classified in 5 categories-behavior, traceability, controllability, relevance and function. Briefly explain each category.

Your objective is to write a well-documented simple program using classes, a loop, and nested ifs to simulate an ATM using JAVA.

1. Create an ATM class with class variables name, pin, and balance, a constructor with parameters to assign values to the three instance variables, methods to get the name, pin, and balance, and methods to handle validated deposits and withdrawals ( deposit and withdrawal amounts cannot be negative, and withdrawal amount must not be greater than the existing balance).

2. In the ATMTest class, read the names, 4 digit pin numbers, and account balances of two customers into two instances of the ATM class. Display the two customers names, pins, and balances formatted.

3. Now that you have all your customers’ information start your ATM to accomplish the following within an infinite loop,

a). Display a welcome screen with your bank’s information and prompt for and read the customer entered pin.

b). Use a nested if to match the entered pin with one of the two customers’ pins. If the entered pin number matches that of one of the customers, then:

i. Welcome the customer by name and display the balance.

ii. Display option to 1. DEPOSIT, 2. WITHDRAW or 3. EXIT.

iii. If option 1 is selected, then use the instance deposit method to prompt for deposit amount, read, and add a valid deposit amount to the customer’s balance

iv. If option 2 is selected, then use the instance withdrawal method to subtract a valid withdrawal amount from the customers balance

v. If option 3 is selected, go to step a.

4. Should the entered pin number not match either of the two customers, notify the customer that the entered pin is not valid and go to step a.

5. Selection of the EXIT option must display welcome/login screen (step a).

6. Should an incorrect option be entered, notify the user and display the original welcome/login screen (step a).
