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

the second part is Hess

Explanation:

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

i don,t know so just answer mine
