It is either a proton or a neutron . B
<h3>
How to identify the particle</h3>
The particle labeled with an X is a neutral atom or a proton which is symbolically represented as :
AZX
where,
Z = atomic number of the element and is known as the number of protons and number of electron (in the particle)
A = Mass number of the element which is represented as the sum of the protons and neutrons (in the nucleus)
Thus, the statement that best identifies the particle X is that it is either a proton or a neutron

Answer:
melting of ice
Explanation:
Factors decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.
Answer:
(3) Equals the mass of CaO plus the mass of CO₂
Explanation:
The important principle to remember is the Law of Conservation of Mass — the total mass of the reactants must equal the total mass of the products.
Reactants ⟶ products
CaCO₃ ⟶ CaO + CO₂
Mass of CaCO₃ = Mass of CaO + mass of CO₂

(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
Dalton turned Democritus' views on atoms into a scientific theory by employing experimental methods. Atoms can join or detach during chemical processes, but they never transform into a different atom.
Dalton was an excellent polymath, a natural philosopher, and a real scientist. His thorough investigations prompted him to suggest an early atomic theory for which exceptions would be difficult to uncover today:
Dalton offered the following:
Atoms are microscopic particles that make up elements. Atoms of the same element have the same size and mass; however, atoms of other elements have varying sizes and masses when compared to atoms of other elements. Subdivision, creation, and destruction of atoms are all impossible.
All of these ideas were developed after a great deal of testing. Other researchers may replicate his work, and new findings could be included into this atomic idea.
Democritus, on the other hand, was a 5th-century BC Greek philosopher. He conducted no experimental work as far as we know, and none of his publications have survived. He postulated that matter was made up of a single indivisible element known as an atom; the word atom originates from the Greek word oos, which meaning "uncuttable" or "indivisible." So the name atom might be a homage to Democritus.
Answer: Index fossil correlation
Relative dating refers to the age estimation method in which the order of the past events is determined to compare the age of an object, rock or organism with the respect to the other. This method gives the estimated or approximate age of the entity under consideration. It does not give the absolute age. Index fossils are the fossils which are found in a particular geological time. They have a short life span and wide geographical distribution. These fossils can be used to determine the relative age. As, these fossils can be compared with the layers of strata and rocks, where they are found, to know their approx age.
