The hotter an object is, the faster the motion of the molecules inside it. Thus, the heat of an object is the total energy of all the molecular motion inside that object. Temperature, on the other hand, is a measure of the average heat or thermal energy of the molecules in a substance.
Halogens. Ex. fluorine can be the gas,bromine can be the liquid, and iodine could a solid all under room conditions.
Explanation:
The octet rule is a rule that governs how atoms combines with each other. It postulates that atoms will prefer to have the stable configuration of noble gases by having eight electrons in their outermost shell.
Compounds forms when atoms combines to attain stability. The atoms of some elements shows no tendency to combine with themselves or other kinds of atoms because their outer energy levels are completely filled.
The driving force for many interatomic bonding is the tendency to have completely filled outer energy levels like the noble gases.
The various interatomic bonds are formed in the bid of the atoms to be isoelectronic in the outer energy level with the noble gases.
This more stable form may be achieved by losing, or gaining electrons or the sharing of pairs of electrons.

Answer:
A. No precipitate is formed
Explanation:
Hello,
In this case, since the reactions are:
We evidence no formation of insoluble salts or precipitates since both calcium and barium chlorides are largely soluble in water due to the ionic bond which binds them, thus A. No precipitate is formed.
Regards.
