Answer:

5.55 L

Explanation:

This excersise can be solved by the Boyle's law.

This law for gases states that the pressure of a gas in a vessel is inversely proportional to the volume of the vessel.

P₁ . V₁ = P₂ . V₂

The law comes from the Ideal Gases Law, in the first term.

P . V = n . R . T In this case, n . R . T are all constant.

6.35 L . 88.6 kPa = 101.3 kPa . V₂

V₂ = (6.35 L . 88.6 kPa) / 101.3 kPa

V₂ = 5.55 L

It is inversely proportional because, as it happened in this case, pressure was increased, therefore volume decreased.

The R group or side chain of the amino acid leucine is non-polar. The R group of serine is polar. Where would you expect to find

Pani-rosa [81]

Answer:

Serine will be on the exterior of the globular protein while leucine on the interior of the globular proteins

Explanation:

The nature or solubility of the side cham determines the poition of amino acid on the globular protein and it is either hydrophilic or hydrophobic.

Serine is an hydrophilic amino acid and so it is position on the surface of the globular protein (Exterior)

While Leucine side chain is hydrophobic in nature is positioned on the interior of the globular protein.

What kind of chemical bonds are represented by the product in the following diagram?

katovenus [111]

The chemical bonds in CH4 are all single bonds. C only can bond 4 times because it needs 8 electrons in it's outer shell and only has four right now. The bonds represented are all single bonds because there are two electrons present on each side of the carbon. Two electrons, in this case, equals one bond.
