Answer:
The answer to your question is molality = 0.61
Explanation:
Freezing point is the temperature at which a liquid turns into a solid if a solute is added to a solution, the freezing point changes.
Data
Kf = 1.86 °C/m
molality = ?
ΔTc = 1.13°C
Formula
ΔTc = kcm
Solve for m
m = ΔTc/kc
Substitution
m = 1.13 / 1.86
Simplification and result
m = 0.61
Answer:
The Concrete has a lower specific heat.
Explanation:
It is because when copper is hammered into a sheet (malleable) or drawn into a wire (ductile), layers of atoms move past one another without disrupting the force between the cations and the negative 'sea' of electrons. it is because of the non directional nature of the metallic bond.
- malleable is a term used to describe material that can be pounded into shapes
- A ductile material is one that can be pulled out, or drawn, into a long wire
- Metal is class of elements characterized by physical properties that include shininess, malleability, ductility, and conductivity.
- Conductors are those Metals who conducts electric current and heat

If I can correct, A, B, and C are correct, but, for certain, D is not correct. Particles do have intermolecular forces.
