C. nucleus because that is where most of an atom's weight is located.
Answer: Medicine is a scientific field whose subject of research is the health and well-being of living whips.
Explanation:
Primarily medicine deals with the study of man and the treatment of man, but also of some animal species. Two principles are founded: theoretical research and practical, or often called a clinical policy. The academic and research law will enable a specific area, disease, congenital disability, or condition to be defined, studied in detail, and after the conclusion of tests performed. Concluded medical theory is most often put into a usable form through various educational processes, which will lead to the ultimate goal - to improve the health of living forms on which this theory will be applied.

<u>Answer:</u> The for the reaction is -205.4 kJ.
<u>Explanation:</u>
Hess’s law of constant heat summation states that the amount of heat absorbed or evolved in a given chemical equation remains the same whether the process occurs in one step or several steps.
According to this law, the chemical equation is treated as ordinary algebraic expressions and can be added or subtracted to yield the required equation. This means that the enthalpy change of the overall reaction is equal to the sum of the enthalpy changes of the intermediate reactions.
The chemical equation for the reaction of methane and chlorine gas follows:
The intermediate balanced chemical reaction are:
(1)
(2)
The expression for enthalpy of the reaction follows:
Putting values in above equation, we get:
Hence, the for the reaction is -205.4 kJ.
Answer:
yes is very possible to be
