Answer:
The correct answer is: Serine, Histidine, Aspartate
Explanation:
The catalytic triad of an enzyme is composed of three aminoacid residues which are the most important for its catalytic activity. They are located in the catalytic site of the enzyme. In the case of chymotrypsin- a serine protease, the catalytic triad is composed by serine, histidine and aspartate (Ser-His-Asp). Serine proteases hydrolyse peptidic bonds in proteins and peptides. To do that, the histidine-which interacts with the aspartate by a hydrogen bond so its pKa increases- take a proton from the serine. Thus, deprotonated serine is able to attack the peptide bond and to perform hydrolysis.
Answer:
An element is atoms with the same number of protons.
Explanation:
Protons, electrons, and neutrons.
<span>If you used more water, the molarity would go down since molarity is moles/liter, and the opposite if you used more water.
If the acid absorbed water, the molarity would go down because the absorbed moisture will skew the weight of the acid up.
That would make the molarity go down since there would have been unreacted acid in the spilled liquid.</span>

Answer:
CaCO₃(s) + 2 H⁺(aq) + 2 Cl⁻(aq) ⇒ Ca²⁺(aq) + 2 Cl⁻(aq) + H₂O(l) + CO₂(g)
Explanation:
Let's consider the molecular equation that occurs when CaCO₃(s) reacts with HCl(aq).
CaCO₃(s) + 2 HCl(aq) ⇒ CaCl₂(aq) + H₂O(l) + CO₂(g)
The complete ionic equation includes all the ions and the compounds that do not dissociate in water.
CaCO₃(s) + 2 H⁺(aq) + 2 Cl⁻(aq) ⇒ Ca²⁺(aq) + 2 Cl⁻(aq) + H₂O(l) + CO₂(g)
