1.     Find the enthalpy change for the reaction       (5 points)

         CS2 (l)  + 3 O2 (g) → CO2 (g)  + 2 SO2(g)      

When:   C(s) + O2(g) → CO2 (g)             

                       S(s) + O2 (g) → SO2(g)              

               C(s) + 2S(s) → CS2(l)       


the mass of a typical car is m=1000 kg, so it's weight on the earth's surface is mg=9800N. suppose you have two containers, one with N electrons and another with N protons. These two containers are placed a distance 10 m apart, and the electric force between them is equal to the weight of the car. find N.

· Declare an array as Car with size 10.

· Take 10 Car’s information from user and store them in specified array.

· Call findCarList method from Main class to get all cars information related to a given model name and display then within this method.

· Model name should be taken from Main class and pass to findCarList method as argument as well as Car array (with size 10).

Design findCarList method in Car classas follows:

· it will take a model(car model) as parameter and array of cars (with size 10)

· displays List of cars for the given model from the list .

· If there are no cars, then shows “No cars found”.


Input numbers from the user and find the sum of all those input numbers until the user inputs zero. In other means, the loop should end when the user enters 0. Finally, display the sum of all those numbers entered by the user
