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.
Bond length increases because single bond is longer than double bond and strength decreases
Answer:
1 = oxidation
2 = reduction
Explanation:
Oxidation:
Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.
2I- ----> I₂+ 2e⁻
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.
F + e⁻ ----> F⁻
Consider the following reactions.
4KI + 2CuCl₂ → 2CuI + I₂ + 4KCl
the oxidation state of copper is changed from +2 to +1 so copper get reduced.
CO + H₂O → CO₂ + H₂
the oxidation state of carbon is +2 on reactant side and on product side it becomes +4 so carbon get oxidized.
Na₂CO₃ + H₃PO₄ → Na₂HPO₄ + CO₂ + H₂O
The oxidation state of carbon on reactant side is +4. while on product side is also +4 so it neither oxidized nor reduced.
H₂S + 2NaOH → Na₂S + 2H₂O
The oxidation sate of sulfur is -2 on reactant side and in product side it is also -2 so it neither oxidized nor reduced.
All given elements belong to second period of periodic table. And we know that going from left to right along the period the number of shells (Principle Quantum Number) remains constant and the number of protons (atomic number) increases, due to this increase in nuclear charge the valence electrons are more attracted towards the nucleus resulting in decreasing the atomic radii, Hence, the atomic radii from larger to smaller radii are as ,

Answer:
pH = pKa = 4.75
Explanation:
The pH of a buffer solution is calculated using Henderson Hassalbalch's equation.
The equation is:
Where
pKa = -log (Ka) = 4.75 [for acetic acid]
[salt] = concentration of salt or the conjugate base, in the given example it is sodium acetate
[acid] = concentration of acid , here it is acetic acid
As given that the concentration of both the salt and acid is same it means
Thus the pH of solution will be equal to its pKa.
