Ammonium nitrate decomposes to N2O and water at temperatures between 250 deg. celcius and 300 deg. celcius. write a balanced chemical recation describing the decomposition of ammonium nitrate, and calculate the standard heat of reaction using the appropriate enthalpies of formation. please include phases.2)chlorofluorocarbons (CFCs) such as CF2CL2 are refrigerants whose use has been phased out because of tehir destructive effect on earth's ozone layer. the standard enthalpy of evaopration of CF2Cl2 is 17.4 kj/mol, cmpared with delta H of vaporization= 41 kj/mol for liquid water. how many grams of liquid CF2CL2 are needed to cool 105.7g of water from 42.4 to 26.3 degrees celcius? the specifi heat of water is 4.184 j/g degrees celcius.
