Chemical reaction: 4PBr₃(g) → P₄(g) + 6Br₂<span>(g).
</span>Pressure equilibrium constant (Kp) express the relationship between product pressures and reactant pressures. The partial pressures of gases are used to calculate pressure equilibrium constant.
Kp = (p(P₄) · p(Br₂)⁶) ÷ p(PBr₃)⁴.
p(P₄) - partial pressure of phosphorus.
p(Br₂) - partial pressure of bromine.
Answer:
The answer to your question is below
Explanation:
Elements in group 1A all:
a. gain 1 electron This option is wrong, elements in group 1A loses one electron.
<u>b. lose 1 electron </u><u>This option is right.</u>
c. are non-metals This option is incorrect, elements in group IA, are metals.
d. have 2 energy levels This option is incorrect, only one element in each group has 2 energy levels.
If we work it out with direct proportions, the vapor pressure of propanone is 56 degrees Celsius. The atmospheric pressure is about 101 kPa. If the vapor pressure is equal to the atmospheric pressure, the substance boils. Therefore, if we hold a linear proportion, 45/56 = x/101. 56x = 101*45, x = 101*45/56 = 81. The closest choice here is (3) 70 kPa.

Ionic bond:
A bond resulting from the attraction between oppositely charged ions; one atom gives another electrons.
Covalent Bond:
A bond resulting from the shaing of pairs of electrons between two atoms.
(+1) + (-1) = 0
Answer:
The pump work is 3451 kJ/s
Explanation:
Pump work (W) is calculated as
where
is the enthalpy of water at its final state
is the enthalpy of water at its initial state
is water mass flow
For liquids, properties are evaluated as saturated liquid. From the figure attached, it can be seen that
