<span>The ideal gas law.
PV=nRT
pressure x volume = moles x Faraday's constant x Temp Kelvin (C+273)
Original data
Pressure 1 atmosphere
Volume 1 liter
Temp 25C = 298K
New data
Volume 0.5 liter
pressure X
Temp 260C = 533K
P1v1T1 = P2v2T2
plug and chug.
(1)(1)(293) = (x)(0.5)(533)
Solve for X, which is the new pressure. </span>
Answer:
Explanation:
A) Formal charges represent an actual separation of charges.(FALSE)
(B) ΔHo rxn can be estimated from the bond enthalpies of reactants and products.(TRUE)
C)All second-period elements obey the octet rule in their compounds(FALSE).
(D)The resonance structures of a molecule can be separated from one another in the laboratory.(FALSE)
Bond enthalpy which is also reffered to as bond energy is the amount of energy that is required to break one mole of a bond.
taking the single bond between Oxygen and Hydrogen into considerationthe bond energy between their single bond is 463 kJ/mol.
formal charge is used for the comparison of the number of electrons present around an atom in a particular molecule with the number of electrons present around a neutral
What did Dalton's atomic theory contribute to science?
Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass.
7 is neutral on the pH scale
