Explanation: When an object moves from its initial position, it acquires some energy. This energy is called kinetic energy, as it is governed by the motion of an object. ... Thus, it is concluded that kinetic energy is the energy an object has due to its motion.
Answer:
The answer to your question is a balanced equation
Explanation:
Chemical formulas are extremely useful in chemistry and these formulas follow the law of proportions but not the law of conservation of matter.
Coefficients indicate that an equation is balanced if these numbers are in proportion but it is not the answer.
Balanced equation is a feature of the law of conservation of matter.
Subscripts are necessary for chemical reactions but they are not a feature of the law of conservation of matter.
Answer : The chemical formula for the compound is, 
Explanation :
When the element 'M' react with the
to give
.
The balanced chemical reaction is,

In this reaction, 'M' is in mono-atomic form and
is in diatomic form.
By the stoichiometry,
2 moles 'M' react with the 1 mole of
to give 2 moles of
.
Therefore, the chemical formula of the compound is, 
The number of protons among the 2 isotopes remain the same, what varies is the number of neutrons between the 2 isotopes. The isotope with the larger mass number possess a greater number of neutrons compared to the other one.
