Answer:
704.25 atm
Explanation:
From the ideal gas equation
PV = nRT
P = nRT/V
Molar volume (V/n) = 34.7 cm^3/mol, n/V = 1/34.7 = 0.0288 mol/cm^3
R = 82.057 cm^3.atm/mol.K
T = 25°C = 25+273 = 298 K
P = 0.0288 × 82.057 × 298 = 704.25 atm
Through mass spectrometry, we can define 4 different isotopes of the BrCl molecule:
⁸¹Br³⁷Cl, ⁸¹Br³⁵Cl, ⁷⁹Br³⁷Cl, ⁷⁹Br³⁵Cl
Masses of the different individual isotopes:
³⁷Cl=36.966
³⁵Cl=34.968
⁸¹Br=80.916
⁷⁹Br=78.918
Masses of 4 different isotopes of the BrCl molecule:
⁸¹Br³⁷Cl=80.916+36.966=117.882
⁸¹Br³⁵Cl=80.916+34.968=115.884
⁷⁹Br³⁷Cl=78.918+36.966=115.884
⁷⁹Br³⁵Cl=78.918+34.968=113.886
Answer:
the relationship between fleas and a dog is a parasitic relationship.
The pH of the solution is mathematically given as
PH=7.21
<h3>What would be the pH of the solution?</h3>
Question Parameters:
sodium hydrogen sulfite (NaHSO3) to 50 mL of water.
Generally, the equation for the Chemical Reaction for the acid dissociation is mathematically given as
HSO3- + H2O ---> H3O+ + SO3^2-
Therefore
A-=HA
pH=pKa
Since pKa NaHSO3=7.21
Hence, PH=7.21
