Answer:
Element
Explanation:
A Substance, either an element or compound, is a single kind of matter that is pure, having a consistent makeup and specific properties. Elements consist of a single type of atom while compounds consist of two or more types of atoms.
The single kind of matter that is pure, having a specific makeup and specific properties is termed as a Substance. A substance can be classified as an element or a compound. Elements consist of only one type of atom and cannot be broken down by a chemical change. On the other hand, compounds consist of two or more types of atoms. It's essential to note that both elements and compounds have a constant composition from point to point, but mixtures don't necessarily maintain the same composition throughout.

Cl2(aq) + 2Brmc003-1.jpg(aq) mc003-2.jpg 2Clmc003-3.jpg(aq) + Br2(aq)
I think the chemical reaction is:
Cl2(aq) + 2Br-(aq) = 2Cl-(aq) + Br2(aq)
The oxidation in this reaction is the reaction for bromine where the charge goes from -1 to a neutral charge while the reduction reaction is showed by the chlorine from a neutral charge to a -1 charge.
The experiment shows that the atoms are mostly empty spaces with most of the mass concentrated at the center, which is the nucleus of the atom.
Rutherford's model also called Rutherfords' atomicmodel was a model describing the nuclear atom or the planetary model of the atom. It gave a description of the structure of atoms.
It was proposed the year 1911 by the New Zealand-born physicist named ErnestRutherford. This model was used to describe the atom. It described the atom as tiny and dense which has a positively charged core called the nucleus.
In the nucleus of the atom, almost all the mass is the atom is concentrated. Around the nucleus, there are the light, negative particles which are called electrons. These circulate around the nucleus at some distance like planets revolve around the Sun.
Therefore, the experiment shows that the atoms are mostly empty spaces with most of the mass concentrated at the center, which is the nucleus of the atom.

2.specific Heat
3.thermal equilibrium
4.Heat of Fusion
Answer: Option (3) is the correct answer.
Explanation:
When two substances or objects at the same temperature do not exchange heat with each other then this state is known as thermal equilibrium.
Whereas latent heat is the release or absorption of energy at a constant temperature.
Specific heat is the amount of heat per unit mass necessary to increase the temperature by one degree Celsius.
Heat of fusion is the amount of energy required to change the state of matter or substance.
Thus, we can conclude that out of the given options, thermal equilibrium describes the point when two objects reach the same temperature and there is no longer a transfer of energy through heat.
B) neutralization
C) deposition
D) reduction
