Answer: (D) Are there solvents mixed in (or is it water based)?
The correct option is D. 2) Anti-bonding electrons or lone pairs. These lone pairs, and bonds helps to form the shape which keeps these electrons separate as possible.
Given mass of Scandium = 50.0 g
Increase in temperature of the metal when heated = 
Heat absorbed by Scandium = 
The equation showing the relationship between heat, mass, specific heat and temperature change:

Where Q is heat = 
m is mass = 50.0 g
ΔT = 
On plugging in the values and solving for C(specific heat) we get,
=50.0g(C)(
)
C = 0.491
Specific heat of the metal = 0.491
It's a thermodynamic quantity equal to the enthalpy minus the product of entropy and the absolute temperature
Answer:
he average atomic mass of an element is the sum of the masses of its isotopes, each multiplied by its natural abundance
