Elis [28]3 years ago
3 0

Answer:

Percent by mass involves the weight in grams

While Percent by volume involves the weight in moles

Explanation:

Percent by mass (m/m) is the mass of solute divided by the total mass of the solution, multiplied by 100 %.

While Percent by volume (v/v) is the volume of solute divided by the total volume of the solution, multiplied by 100 %.

Molecular orbital theory correctly predicts paramagnetism of oxygen gas. true or false
PtichkaEL [24]

Answer: Yes.

Explanation:

Oxygen has a bond order of two. The bond order of Oxygen molecule is calculated, where the [<em>eight valence electrons in bonding molecular orbitals</em> minus (-) <em>four valence electrons in antibonding molecular orbitals</em>]/2 in the electron configuration.

Atoms/molecules where electrons are paired are diamagnetic (repelled by both poles of a magnetic); while atoms/molecules that have one or more unpaired electrons are paramagnetic (attracted to magnetic field).

The two unpaired electrons of dioxygen molecules has made it <u>paramagnetic</u>. By pouring liquid oxygen between the poles of a strong magnet, the liquid stream will be contained by the filed and fills up the space between the poles.
