Answer:
Explanation:
since the problem involves pressure and volume, boyle's law is used.
P1V1= P2V2
P1 = 1.85 atm
P2 =?????
V1
Answer:
3.913x10^22 atoms
Explanation:
We have come to discover that 1 mole of any substance contains 6.02x10^23 atoms as explained by Avogadro's hypothesis.
This means that 1 mole of Hg contains 6.02x10^23 atoms.
Therefore, 0.065 moles of Hg will contain = 0.065 x 6.02x10^23 = 3.913x10^22 atoms
The helium would expand into the air of the room. Depending on how big the room is, and the amount of helium in the jar, it could cause damage to health. The only way this would happen is if the room was small and the jar was big.
I hope this helps!
Answer:
CH3NH2 : Hydrogen bonding and London dispersion forces
F2 : Hydrogen bonding, dipole-dipole and London dispersion forces
NOF : Dipole-dipole forces
C2H6 : London dispersion forces
H2O : Hydrogen bonding and London dispersion forces
Increasing order of boiling point:
F2
C2H6
NOF
CH3NH2
H20
Explanation:
London dispersion forces exist in all substances
CH3NH2 : The hydrogen bonding in the amine group and the assymetry of the molecule makes the hydrogen bonding and dipole-dipole bonds from the methyl group.
F2 : The bond is non polar because its a homonuclear bond
NOF : Dipole-dipole forces due to difference in elecronegativity between all the atoms involved and assymetry
C2H6 : London dispersion forces because all dipole-dipole forces are cancelled out due to the symmetry of the molecule
H2O : Hydrogen bonding between hydrogen and oxygen and the assymetry of the molecule
Order of boiling points: London dispersion forces, followed by dipole-dipole forces and hydrogen bonding is the strongest
Answer:
1& 4
Explanation:
1. The average kinetic energy of the particles in a substance determines the substance's temperature.
4. How fast a substance's particles are moving determines how hot or cold the substance is.
