A gas sample is made entirely of carbon dioxide and water, and there are 300 moles of CO2 and 500 moles of H2O. If the total pre

ssure of the sample is 21 atm, what is the partial pressure of H2O ? Ptotal = Pa + Pb+ Pc....... Pa = Xa(Ptotal)

Answer:

Explanation:

Total moles = 300 + 500 = 800 moles

mole fraction of carbon dioxide = 300 / 800 = 3 / 8

water = 500 / 800 = 5 / 8

Total pressure = 21 atm

partial pressure of water = total pressure x mole fraction of water

= 21 x 5 / 8

= 13.125 atm

Answer:

ΔS° = 180.5 J/mol.K

Explanation:

Let's consider the following reaction.

4 NH₃(g) + 5 O₂(g) → 4 NO(g) + 6 H₂O(g)

The standard molar entropy of the reaction (ΔS°) can be calculated using the following expression.

ΔS° = ∑np × S°p - ∑nr × S°r

where,

ni are the moles of reactants and products

S°i are the standard molar entropies of reactants and products

ΔS° = 4 mol × S°(NO(g)) + 6 × S°(H₂O(g)) - 4 mol × S°(NH₃(g)) - 5 mol × S°(O₂(g))

ΔS° = 4 mol × 210.8 J/K.mol + 6 × 188.8 j/K.mol - 4 mol × 192.5 J/K.mol - 5 mol × 205.1 J/K.mol

ΔS° = 180.5 J/K

This is the change in the entropy per mole of reaction.

Igoryamba

Answer:

internal fertilization

Explanation:

Internal fertilization enhances the fertilization of eggs by a specific male. Fewer offspring are produced through this method, but their survival rate is higher than that for external fertilization.
