When Cl2 gas is added to water during the disinfection of drinking water, it hydrolyzes with the water to form HOCl. The disinfe

ction power of the acid HOCl is 88 times better than its conjugate base, OCl-. The pKa for HOCl is 7.5. (a) What % of the total disinfection power (i.e., HOCl + OCl-) exists in the acid form at a pH = 6? (b) At pH = 7? (By "percentage of disinfection power" MZ means  expressed as a percent.) Answer: 97% and 76%

Which atom, selenium (Se) or Arsenic (As), has the higher electron affinity and why?
IrinaVladis [17]

Answer:

5. Selenium, because it does not have a stable, half-filled p subshell and adding an electron does not decrease its stability.

Explanation:

Electron affinity is the amount of energy released when an isolated gaseous atom accepts electron to form the corresponding anion.

Selenium:-

The electronic configuration of the element is:-

[Ar]3d^{10}4s^24p^4

Arsenic:-

The electronic configuration of the element is:-

[Ar]3d^{10}4s^24p^3

The 4p orbital in case of arsenic is half filled which makes the element having more stability as compared to selenium.

Thus, selenium has higher electron affinity because adding electron does not decrease the stability as in case of arsenic.

What type of compound does the formula, CuCl2, represent?<br> a. ionic salt<br> b. covalent molecule
Rainbow [258]
The answer is:  [B]:  "ionic salt" .
___________________________________________________
Note:  There is no "sharing of electrons" among the elements in this compound; so this compound in NOT a "covalent molecule".

However, there is ionic bonding:  Cu²⁺ and  Cl⁻  ;  to form:  "CuCl₂" .
