Question

5 g of ammonium nitrate was dissolved in 60 g of water in an insulated container. The temperature at the start of the reaction was 23.0°C and at the end it was 19.0°C. Use the equation below to calculate the energy absorbed by the reaction. (Hint: the mass of the solution changes when ammonium nitrate is added.)

Answer 1

Answer: The energy absorbed by the reaction from the water is 996 Joules.

Step-by-step explanation:

Energy absorbed by the reaction or energy lost by the water to the reaction,Q.

Mass of the the reaction ,m = 60 g

Specific heat of water = c = 4.15 J\g ^oC

Change is temperature=

Negative sigh indicates that energy was given by the water to the reaction.

The energy absorbed by the reaction from the water is 996 Joules.
