When ammonium nitrate is added to water, an endothermic reaction occurs and ________________________.Question 8AnswerA.nothing changes.B.the temperature rises.C.heat is given out.D.the temperature of the reaction mixture falls.

A student adds a small amount of ammonium chloride to a beaker of water. The temperature of water decreased from 21oC to 17oC. Which type of reaction has occurred and why? Question 3AnswerA.Endothermic reaction because heat is absorbed. B.Exothermic reaction because heat is released.C.Exothermic reaction because heat is absorbed.D.Endothermic reaction because heat is released.

When ammonium nitrate, NH4NO3(s) is added to water at 25 °C, it dissolves spontaneously and the temperature of the solution decreases. This indicates that the factor causing the substance to dissolve is a change in ________.Group of answer choicestemperatureenergyenthalpyentropy

Liam investigates the energy released when ammonium nitrate is dissolved in water.His method is as follows:Liam’s results were:Initial temperature = 20 ºCFinal temperature = 14 ºCHow can you tell from the student’s results that the reaction is endothermic?There is a rise in temperature.Effervescence (fizzing) occurs due to the production of a gas.There is a fall in temperature.The ammonium nitrate crystals disappear and dissolve into the solution.I DON'T KNOWSUBMIT ANSWER

Label each of the following as being an example of an endothermic or an exothermic reaction.a. a reaction where the surroundings decrease in temperature from 25 oC to 19 oC  Blank 1 Question 26b. N2(g)  +  3 H2(g)  -->  2 NH3(g)    ΔH = -92.4 kJ

. A reaction is allowed to take place in an insulated container containing 100 mL of water. If the reaction is endothermic, what happens to the temperature of water?*2 pointsThe temperature of water goes down.The temperature of water goes up.The temperature of water does not change.
