Answer:

The relationship of pH and concentration of H+ ion is pH = -lg[H+]. So the concentration of H+ is 10^(-2). And [OH-][H+]=10^(-14). pOH + pH = 14. So the right answer is A.

The following reactions take place in the ozone layer by the absorption of ultraviolet light.
____ [38]

Answer:

Option B will require a shorter wave length of light.

Explanation:

The bonding between Ozone (O3) and Oxygen (O2) can be used to explain why the breaking of oxygen into Oxygen radicals will require a shorter wave length.

  • The bond between Oxygen (O2) is a double bond while Ozone (O3) has an intermediate bond between a double bond and a single bond.
  • The bond order of Oxygen (O2) is equals 2 while that of Ozone (O3) is 1.5. Since the bond order of oxygen is higher, it will require more energy to break the bond compared to breaking the Ozone (O3) bond.
  • Recall that Energy is inversely proportional to wave length.
  • So it will require a shorter wave length to break the Oxygen (O2) into its radicals.

A sealed flask contains Ne, Ar, and Kr gas. If the total pressure in the flask is 3.782 atm, the partial pressure of Ne is 0.435
spin [16.1K]

Answer:

P_{Ar}=1.734atm = partial pressure of Ar

Explanation:

Acccoding to dalton's law of partial pressure total pressure of system is equal to alzebraic sum of all partial pressure.

P_{total} =P_{Ne}+P_{Ar} +P_{Kr}

P_{total}=3.782atm

P_{Ne}=0.435 atm

P_{Kr}=1.613atm

P_{Ar}=P_{total}-P_{Ne}-P_{Kr}

P_{Ar}=3.782-0.435-1.613

P_{Ar}=1.734atm =partial pressure of Ar
