Calculate the concentration of hydrochloric acid if 50.0 mL of hydrochloric acid is neutralized by 25.0 mL of 2.0 M sodium hydro

xide. The neutralization reaction is shown below HCl + NaOH > H2O + NaCl

Answer:

1.0M HCl is the concentration of the acid

Explanation:

Based on the reaction, 1 mole of NaOH reacts per mole of HCl. That means the moles added of NaOH in the neutralization = Moles of HCl in the solution. With the moles and the volume in Liters we can find the molar concentration of HCl

<em>Moles NaOH = Moles HCl:</em>

25.0mL = 0.025L * (2.0moles / L) = 0.050moles HCl

<em>Molarity:</em>

0.050moles HCl / 0.0500L =

<h3>1.0M HCl is the concentration of the acid</h3>

Sodium thiosulfate, na2s2o3, is used as a "fixer" in black and white photography. identify the reducing agent in the reaction of
aev [14]
Answer is: reducin agent in this reaction is thiosulfate (S₂O₃²⁻).
Balanced chemical reaction: 2S₂O₃²⁻(aq) + I₂(aq) → S₄O₆²⁻(aq) + 2I⁻<span>(aq).

In uncompetitive inhibition, the inhibitor can bind to the enzyme only after the substrate binds first. (T/F)
Veronika [31]

Answer:

True

Explanation:

In an uncompetitive inhibition, initially the substrate [S] binds to the active site of the enzyme [E] and forms an enzyme-substrate activated complex [ES].

The inhibitor molecule then binds to the enzyme- substrate complex [ES], resulting in the formation of [ESI] complex, thereby inhibiting the reaction.

This inhibition is called uncompetitive because the inhibitor does not compete with the substrate to bind on the active site of the enzyme.

Therefore, in an uncompetitive inhibition, the inhibitor molecule can not bind on the active site of the enzyme directly. The inhibitor can only bind to the enzyme-substrate complex formed.

When do d orbitals start getting filled
Ghella [55]

Answer & Explanation:

D orbitals begin filling with electrons after the orbital found in the 4s sublevel is filled. This occurs because the d sublevel is first found in the.
