Answer:
Explanation:
300 ml x300mm Hg/500 mm Hg= 180 ml
pressure goes up volume goes down
P1V1 =P2V2
V2= V1 x P1/P2
Answer:
See explanation
Explanation:
Electrons transition between energy levels in an atom due to gain or loss of energy. An electron may gain energy and move from its ground state to one of the accessible excited states. The electron quickly returns to ground state, emitting the energy previously absorbed as a photon of light. The wavelength of light emitted is measured using powerful spectrometers.
Atoms can be excited thermally or by irradiation with light of appropriate frequency.
Answer:
circulatory system
Explanation:
it is what makes oxygen circulate
A polar bond is a bond where there is an uneven distribution of charge in the molecule, due to the ability of more electronegative atoms to attract electron pairs towards themselves which creates an electric dipole. The more electronegative atom gets a partial positive charge and the less electronegative atom gets a partial positive charge.
For a bond between two atoms to be polar, the difference in electronegativity between the two atoms should be roughly between 0.5 and 2.0. In this case, the more electronegative atom will draw the charge density towards itself to create the dipole, but not strong enough to completely strip the other atoms of electrons. The bigger the difference in electronegativity, the more polar the bond.
Answer:
Explanation:
Hello,
In this case, by using the ideal gas equation:
We can compute the mass of neon gas at the given conditions by firstly computing the moles and also considering the temperature in kelvins (298K):
Finally, by using the atomic mass of neon gas (20.18g/mol) we compute the required mass to fill the 5.00-L container:
Best regards.
