Answer:
Aluminum, because it is in group 13 and has three valence electrons.
To determine the heat required to raise a body's termperature by a certain number of degrees C, we use the equation,
H = mcpdT
where m is mass, cp is specific heat, and dT is the temperature difference. Substituting the known values,
H = (30.0 g)(0.90 J/gC)(75 - 25)
H = 1350 J
Thus, there is a need for 1350 J of heat for the process.
