The enthalpy change upon dissolving 80 grams of ammonium nitrate in water is +25.7 kJ. Will the solution feel cold or warm to touch? Group of answer choicescoldwarm

Measurements show that the enthalpy of a mixture of gaseous reactants decreases by 258.kJ during a certain chemical reaction, which is carried out at a constant pressure. Furthermore, by carefully monitoring the volume change it is determined that −51.kJ of work is done on the mixture during the reaction.Calculate the change in energy of the gas mixture during the reaction. Round your answer to 3 significant digits. kJIs the reaction exothermic or endothermic?

A student is determining the enthalpy of solution for ammonium nitrate by addingammonium nitrate to a calorimeter and measuring the temperature change.The accepted value is ΔHsol’n = 25.7 kJ/mol.A student, not paying attention, adds 1.5g of ammonium nitrate instead of 1.0g.When they perform their calculations, they use 1.0g as the mass.Will their calculation result in an answer that is higher than the accepted value orlower? Explain. (2 marks)
