Question

reflecting on the laboratory experiment. what were the learning goals of this lab experiment? choose three correct answers. to compute the enthalpy of a reaction that cannot be measured directly using a simple calorimeter. to compute a reactions enthalpy directly using mass measurements and a calorimeter. to demonstrate that different reactions have similar enthalpies. to use mass and temperature data to do computations involving heat

Explanation:

Enthalpy calculations and using calorimetry - related data are common learning goals in chemistry experiments. Computing enthalpy of non - directly measurable reactions, direct enthalpy computation with mass and calorimeter, and using mass and temperature data for heat computations are valid chemistry - related learning goals. Demonstrating similar enthalpies for different reactions is less of a common core learning goal.

Answer:

1. to compute the enthalpy of a reaction that cannot be measured directly using a simple calorimeter
2. to compute a reaction's enthalpy directly using mass measurements and a calorimeter
3. to use mass and temperature data to do computations involving heat
