According to my mind and my biology test, it is B) Low concentration of oxygen IN THE BLOOD; high concentration co2 in the tissue
konstantin123 [22]3 years ago
3 0

Answer:

A. High concentration of oxygen in the blood; high concentration of carbon dioxide in the body tissues

Explanation:

Diffusion occurs from a region of higher concentration to a region of lower concentration. Diffusion occurs against a concentration gradient.

High concentration of oxygen in the blood causes oxygen to leave the blood and enter body tissues.  High concentration of carbon dioxide  in the body tissues causes carbon dioxide to leave body tissues and enter the blood.

From top to bottom in most groups of elements atomic radii tend to
kogti [31]
As you go down a group on the periodic table, atomic radii tend to increase because elements with larger atomic numbers have more occupied electron levels which take up more space surrounding the nucleus.

I hope this helps.

Calculate the standard emf for the following reaction:
krek1111 [17]
In order to solve this, we need to know the standard cell potentials of the half reaction from the given overall reaction.
The half reactions with their standard cell potentials are:
<span>2ClO−3(aq) + 12H+(aq) + 10e- = Cl2(g) + 6H2O(l) 
</span><span>E = +1.47 
</span>
<span>Br(l) + 2e- = 2Br- 
</span><span>E = +1.065
</span>
We solve for the standard emf by subtracting the standard emf of the oxidation from the reducation, so:
1.47 - 1.065 = 0.405 V

How many of the following molecules have sp2 hybridization on the central atom? hcn so2 ocl2 xecl2.
GrogVix [38]

Only one molecule have <u>sp2 </u>hybridization on central atom and that is <u>SO₂</u>.

<u>XeCl₂</u> have <u>sp3d </u>hybridization.

<u>OCl₂</u> have <u>sp3 </u>hybridization.

<u>HCN </u>have <u>sp </u>hybridization.

Hybridization is defined as the concept of mixing two atomic orbitals to give rise to a new type of hybridized orbitals.

Hybridization intermixing usually results in the formation of hybrid orbitals having entirely different energies, shapes, etc.
