What were the learning goals of this lab experiment? check all that apply.

to use mass and temperature data to do computations involving heat

to demonstrate that different reactions have different enthalpies

to compute a reaction’s enthalpy directly using mass measurements and a calorimeter

to compute the enthalpy of a reaction that cannot be measured directly using a simple calorimeter

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
