5g 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.

1.00464 kJ of energy is absorbed by the ammonium nitrate from the water.

Explanation:

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 =

Change in temperature =

 (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.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
