The answer is asparagine interactions between aspartate and arginine side chains at neutral pH
<h3>
What side chain does arginine have?</h3>
- The amino acid arginine has the formula (H2N)(HN)CN(H)(CH2)3CH(NH2)CO2H.
- A guanidino group is attached to a typical amino acid framework in the molecule.
- The carboxylic acid is deprotonated (CO2) and both the amino and guanidino groups are protonated, resulting in a cation at physiological pH.
- The guanidine group in arginine is the precursor for nitric oxide production. it is a white, water-soluble solid, like all amino acids.

Answer : Al
Explanation :
- For a given redox reaction there must be an oxidizing agent/(s) and a reducing agent/(s).
- the oxidizing agent is the substance that undergoes reduction process (gaining electrons or loss of oxygen atoms), meanwhile, the reducing agent is the substance that undergoes oxidation process (loss of electrons or gaining of oxygen atoms).
- In the reaction above, the oxidation number of (Al) in AlCl3 is (3+). However, the oxidation number of (Al) in the products is zero because it exists as a single element.
Therefore, changing from (3+) to zero means gaining of (3) electrons to neutralize the previously existing (3) protons on (Al) in AlCl3.
So Al is the oxidizing agent..
In 1911, Rutherford performed experiment to determine the structure on atom
Answer:
C) LiOH + HCl → LiCl + H₂O
General Formulas and Concepts:
<u>Chemistry - Reactions</u>
- Synthesis Reactions: A + B → AB
- Decomposition Reactions: AB → A + B
- Single-Replacement Reactions: A + BC → AB + C
- Double-Replacement Reactions: AB + CD → AD + BC
Explanation:
<u>Step 1: Define</u>
RxN A: 2Na + 2H₂O → 2NaOH + H₂
RxN B: CaCO₃ → CaO + CO₂
RxN C: LiOH + HCl → LiCl + H₂O
RxN D: CH₄ + 2O₂ → CO₂ + 2H₂O
<u>Step 2: Identify</u>
RxN A: Single Replacement Reaction
RxN B: Decomposition Reaction
RxN C: Double Replacement Reaction
RxN D: Combustion Reaction
The balanced chemical reaction is:
<span>Mg(OH)2 + 2HCl
--> MgCl2 + 2H2O</span>
So we can see that 2 moles of HCl reacts for every 1 mole
of Mg(OH)2.
moles HCl left = 0.125 M * 0.150 L – (0.125 M * 0.040 L) *
2
moles HCl left = 0.00875 mol
So the concentration of H+ ion is:
[H+] = 0.00875 mol / (0.150 L + 0.040 L)
[H+] = 0.046 M
So the pH is:
pH = - log 0.046
<span>pH = 1.34</span>
