Answer: 1.00464 kJ of energy is absorbed by the ammonium nitrate from the water.
Explanation:
[tex]NH_4(NO_3)+H_2O\rightarrow NH_4OH+NHO_3[/tex]
Mass of water used in reaction = 60 g
Initial temperature of the water before reaction = 23°C
Final temperature of the water after temperature = 19°C
Specific heat capacity of water = [tex]4.186J/g^oC[/tex]
Change in temperature =[tex]\Delta T=19^oC-23^oC=-4^oC[/tex]
[tex]Q=mC\Delta T=60 g\times 4.186J/g^oC\times (-4^oC)[/tex]
[tex]Q=-1,004.64 J=-1.00464 kJ[/tex] (1 kJ = 1000J)
The negative sign means that energy from the water is absorbed by the ammonium nitrate that is this reaction is an endothermic reaction.
The energy of 1.00464 kJ of energy is absorbed by the ammonium nitrate from the water.
