1. Ion selectivity in voltage gated channels depends on the hydration status of the ion. What is the basis of K+ selectivity in

voltage gated K+ channels? a. K+ is repelled by positive charges in the channel pore b. A K+ ion that is not hydrated is stabilized at the outside of the pore and then loses a neutron to allow it to pass

Anni [7]

Answer:

Ka = 4.76108

Explanation:

  • CO(g) + 2H2(g) ↔ CH3OH(g)

∴ Keq = [CH3OH(g)] / [H2(g)]²[CO(g)]

                      [ ]initial         change         [ ]eq

CO(g)              0.27 M       0.27 - x        0.27 - x

H2(g)              0.49 M       0.49 - x        0.49 - x

CH3OH(g)          0                0 + x               x = 0.11 M

replacing in Ka:

⇒ Ka = ( x ) / (0.49 - x)²(0.27 - x)

⇒ Ka = (0.11) / (0.49 - 0.11)² (0.27 - 0.11)

⇒ Ka = (0.11) / (0.38)²(0.16)

⇒ Ka = 4.76108

The O2 molecule breaks apart at lower wavelengths than the O3 molecule. What is the main reason for this?
kozerog [31]

The main reason for this is Average bond of O₂ is shorter and strong from O₃.

<h3>What is ozone?</h3>

Ozone is a blue gas composed of three oxygen atoms bonded together.

It occurs naturally high up in the Earth's atmosphere, where it protects the surface from harmful ultraviolet (UV) rays,

UV radiation will dissociate ozone into an oxygen atom and an oxygen molecule.

Ozone molecules are tetrahedral so the bond angle is  109 degree the electrons in the double bond occupy more space that the non-bonding electron pair.

Oxygen has a small size that leads to smaller O-O bond length.

A lone pair of electrons on both the oxygen repel each other leading to weakening of O-O bond.

O3 has longer and weaker bonds than O2, whereas SO2 has shorter and stronger bonds than SO.

Molecular oxygen, O2, is photolyzed by light of 241 nm and has a bond energy of 498 kJ/mol.

The main reason for this is Average bond of O₂ is shorter and strong from O₃.

uppose you are titrating an acid of unknown concentration with a standardized base. At the beginning of the titration, you read
sweet-ann [11.9K]

Answer:

V_{base}=18.00mL

Explanation:

Hello,

In this case, since you have both the final and initial volume for the titration procedure, clearly, the used volume is computed by the subtraction between them, since it accounts for the employed volume of the base, it turns out:

V_{base}=20.03mL-2.03mL\\\\V_{base}=18.00mL

Best regards.
