Question

reflecting on the laboratory experiment. to find the enthalpy of a reaction in the lab, you measured the drop - down 1 of the reactants and the drop - down 2 change during the reaction. drop - down 1 options: volume, mass, temperature

Explanation:

Enthalpy change ($\Delta H$) of a reaction can be calculated using the formula $q = mc\Delta T$ (where $q$ is heat, $m$ is mass, $c$ is specific - heat capacity, and $\Delta T$ is temperature change). Mass of reactants is needed to calculate heat transferred, and temperature change during the reaction is also crucial for enthalpy determination.

Answer:

First blank: mass
Second blank: temperature
