1)State the First Law of Thermodynamics.                                  

 

 

 

 

 

 

2)Fluorine (F2) and iodine (I2) are both Group 17 elements. Explain with reference to intermolecular forces, why fluorine is a gas and iodine is a solid at room temperature.                                                                             

 

                                                                                              

 

 

 

 

4)When 30 g of ammonium nitrate, (NH4NO3) was stirred into 10 cm3 of water, the temperature fell from 21 oC to 15 oC.

 

5)Calculate the total amount of energy (E) released in this experiment. Ignore the heat capacity of ammonium nitrate. Take the specific heat capacity of the water as 4.18 J g-1 ºC-1. Density of water is 1.00 gcm-3.                                  

 

 

 

 

 

6)This amount of energy [answer to part (i)] was produced by 30 g of ammonium nitrate.  Calculate the energy change per mole of ammonium nitrate.  Include the correct sign for the energy change. Give the answer to two decimal places in kilojoules per mole.
