Give examples that illustrate the use of standard heats of formation in calculating changes in enthalpy or ΔH of reactions.
State that values of standard states of formation are important because these are
conveniently used to calculate changes in enthalpy, ΔH of many reactions.
Discuss standard state and give examples (Padolina et al., 1995)
- Create (4) java classes. Name them RunEmployee, Employee, FullTimeEmployee, PartTimeEmployee. The Runemployee class shall contain the main method and will be used to execute the program.
- Write a simple payroll program that will display employee's information. Refer to the UML Class Diagram for the names of the variable and method. This should be the sequence of the program upon execution:
- Ask the user to input the name of the employee
- Prompt the user to select between full time and part time by pressing either F (full time) or P (part time).
- If F is press, ask the user to type his monthly salary. Then, display his name and monthly salary.
If P is pressed, ask the user to type his rate (pay) per hour and the number of hours he worked for the entire month separated by a space. Then, display his name and wage.

In solvolysis of alkyl halides, substitution of alkyl groups at the B 'carbon atom increases E1 over SN1.
Objective: Distinguish between electromotive forces and potential differences.
Material: A circuit Diagram
Procedure:
- Draw a circuit diagram with two batteries, 1 light bulb, and switch. You can apply your creativity provided that the appropriate symbols are used.
- Label the electromotive force and the potential difference.
Question: How does an electromotive force differ from potential difference?
- Create a project named LabExer2
- Construct a simple purchasing program based on the UML Class Diagram below.
- itemName: String
- itemPrice: double
- itemQuantity: int
- amountDue: double
- setItemName(StringnewitemName): void
- setTotalCost(int quantity, double price): void
- getItemName(): String
- getTotalCost(): double
- readInput(): void
- writeOutput(): void
storing the input to the next variable name based on data type
For String s.nextLine()
For int s.nextInt()
For double: s.nextDouble()
