1. Which of the following atoms would you expect to release less energy than carbon when an electron is added to its valence?
neon (Ne)
2. Suppose a laboratory wants to identify an unknown pure substance. The valence electrons of the substance's atoms feel an effective nuclear charge of +4. If the unknown substance has a higher electronegativity value than silicon (Si), what other characteristics would you expect the substance to exhibit?
It would have smaller atomic radii than Si and higher ionization energies than Si.

<u>Answer:</u> The for the reaction is -810 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 given chemical reaction 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 -810 kJ.
Answer: Anabolism
Explanation:
Chemical reactions that combine simple molecules and monomers to form complex structures are known as ANABOLISM.
Anabolic reactions which are also called biosynthesis reaction is a type of metabolic reaction in the body that forms larger molecules through combination of smaller molecules with the use of energy in the form of ATP molecules. Example if anabolic reactions in the body includes:
- formation of polysaccharide from monosaccharides,
- formation of triglycerides from fatty acids,
- formation of nucleic acids from nucleotides and many among others. I hope this helps, thanks.
