Leno4ka [110]

During the course of a catalytic reaction Substrate is covalently bound and oriented with proximity to the active site residues.

The type of chemical species which can facilitate these reactions is transition metal cations.

<h3>What is an Enzyme?</h3>

These are proteins that act as biological catalysts and accelerate chemical reactions.

evablogger [386]

Answer:

The amount of molecules → 6.02×10²³

Explanation:

Avogadro Number (NA) is the amount of particles that are contained in 1 mol of anything.

It does not matter the mass of compounds, or molecules, 1 mol has 6.02×10²³ particles, the same number for every compound.

1 mol of H₂O that weighs 18 grams has 6.02×10²³ molecules

1 mol of sucrose, that weighs 342 g has 6.02×10²³ molecules

Generally, the NA  is the number of atoms in 12 grams of the carbon-12 isotope.

likoan [24]

Answer:

3.23 atm

Explanation:

Use the equation P₁V₁=P₂V₂.  P₁ and V₁ are initial pressure and volume.  P₂ and V₂ are final pressure and volume.  Solve for P₂.

(1.88 L)(3.81 atm) = (2.22 L)(P₂)

7.1628 L*atm = (2.22 L)(P₂)

P₂ = 3.226 atm
