Answer:
As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points. This means that the melting point and boiling point of metals are more similar to those for ionic compounds than for covalent substances.
Explanation:
The mass in a chemical reaction remains (mostly) the same.
(except for radiation/nuclear fission, in which mass gets converted into energy)
A) The mixing of a substance with another substance due to the motion or movement of its particles is called diffusion.
b) Gaseous particles tend to undergo diffusion because they have kinetic energy.
