1. Calculate the ΔH for the reaction:
CS2 (l) + 2 O2 (g) � CO2 (g) + 2 SO2 (g)
Given:
ΔHfCO2 (g) = - 393.5 kJ/mol;
ΔHfSO2 = -296.8 kJ/mol;
ΔHfCS2 (l) = 87.9kJ/mol

5. A travelling salesman records his mileage at the end of each week in order to make an accurate claim for expenses.
Write a Java code:
* With a class called Travelling which has a calculateExpenses method which is to prompt the user to input the date and the number of kilometres travelled.
* Perform a validation to ensure that the number of kilometres is an integer greater than 0.
* The method should be written within the same class:
- The first 100 kilometres is paid at R1.20 per kilometre.
- If the of kilometres is more than 100, all additional kilometres are paid at R1.50 per kilometre
* Output:
- The date : 04/28/2022
- The number of kilometres travelled: 200
- The total expenses due : R270.0
4. The Litsemba Group Life Insurance company computes annual policy premiums based on the age the customer turns in the calendar year. The premium is computed by taking the decade of the customer's age, adding 15 to it, and multiplying by 20. For example, a 34 year would pay R360 which is calculated by adding the decades (3) to 15 and multiplying by 20. Write a Java application that prompts a user for the current year and a birth year. Pass both to method that calculates and returns the premium amount and display the returned amount. Application should be named Insurance.java . Note: The customer should not be older than 59 years .
