Predict the number of each atom needed to form a molecule of potassium Sulfide.
vladimir2022 [97]

Answer:

2.0 atoms of K and 1.0 atom of S are needed to form a molecule of potassium sulfide.

Explanation:

  • The potassium sulfide has the chemical formula <em>K₂S.</em>

∴ Every 1.0 molecule of K₂S composed of 2.0 atom of K and 1.0 atoms of S.

<u><em>So, 2.0 atoms of K and 1.0 atom of S are needed to form a molecule of potassium sulfide.</em></u>

A purified protein has a molecular mass of 360 kDa when measured by size exclusion chromatography. When analyzed by gel electrop
Dimas [21]

Answer:

A protein has four subunits whose molecular masses are 140, 80, and 60 kDa.

A disulfide bond links the two 80 kDa subunits (possibly identical).

Explanation:

Given that:

A protein has four subunits whose molecular masses are 140, 80, and 60 kDa.

A disulfide bond links the two 80 kDa subunits (possibly identical).

As a result of SDS and dithiothreitol analysis treatment, the molecular masses can not be 360 in total. They are 280, which implies that they are in short of 80 kDa. This means that there are possibilities that two groups with a molecular mass of 80 kDa which are joined by a disulfide bond.

The presence of SDS and dithiothreitol acts as a reducing agent, and they can break disulfide bonds whose pH is greater than 7, i.e. those in basic condition.

An ion with a -2 charge has? A) one missing protein B) two missing protons c) two missing electrons D) two extra electrons
Andreyy89

Answer:

D.

Explanation:

It would not be gain because it would say +6 instead of -2. Having a -2 charge means it wants to loose 2 electrons so it can form a full shell of 8 electrons. It wants to be inert (stable).

- Hope that helps! Please let me know if you need further explanation.
