Answer:
The Inert Pair effect renders Pb(II) as the more stable oxidation state of lead
Explanation:
SnBr4 + PbBr2 ---> SnBr2 + PbBr4
SnBr2 + PbBr4 ---->
The Inert pair effect is mostly observed between group 15-17 in the periodic table. It leads to stability of the lower oxidation state of an element.
The reason for the Inert pair effect is that the s electrons become Inert due to poor shielding of the d and f-electrons. The Inert pair effect is a tendency of the s electrons not to participate in bonding (remain an Inert pair).
Owing to the Inert pair effect, Pb II is more stable than Pb IV
Answer:
, The partial pressure of O2 is = 21 atm
Explanation:
The concept is the pressure exerted by each gas is independent of one another or in other words independent of the pressure exerted by all other gases present.
This means that total pressure is the sum of the individual pressure of each gas by dalton's law.
So, putting the given values we get
43 = P_O2 +15+7
P_O2 = 21 atm
Therefore, The partial pressure of O2 is = 21 atm
PV = nRT
Pressure times volume = number of moles times ideal gas constant times temperature
50mL = .05L
1 atm (.05) = n (.0821) (273)
.05 = n (22.4133)
.022 = n (number of moles)
6.022E23 molecules = 1 mole
.022 x 6.022E23 = 1.325E23 molecules
