Answer:
Following DNA replication, the chromosome consists of two identical structures called (sister chromatids), which are joined at the centromere.
Answer:
molecular weight (Mb) = 0.42 g/mol
Explanation:
mass sample (solute) (wb) = 58.125 g
mass sln = 750.0 g = mass solute + mass solvent
∴ solute (b) unknown nonelectrolyte compound
∴ solvent (a): water
⇒ mb = mol solute/Kg solvent (nb/wa)
boiling point:
- ΔT = K*mb = 100.220°C ≅ 373.22 K
∴ K water = 1.86 K.Kg/mol
⇒ Mb = ? (molecular weight) (wb/nb)
⇒ mb = ΔT / K
⇒ mb = (373.22 K) / (1.86 K.Kg/mol)
⇒ mb = 200.656 mol/Kg
∴ mass solvent = 750.0 g - 58.125 g = 691.875 g = 0.692 Kg
moles solute:
⇒ nb = (200.656 mol/Kg)*(0.692 Kg) = 138.83 mol solute
molecular weight:
⇒ Mb = (58.125 g)/(138.83 mol) = 0.42 g/mol
In a solid, atoms are packed very closely together, almost like an organized grid. They vibrate, and rub against each other, but stay in the same place.
In a liquid, atoms are farther apart, and slide around each other, which is why if you pour water on the ground, it won't stay in any specific shape unless it is in a container. However it does stay together. Gas on the other hand is very spread out with a lot of space in between the individual atoms. All the space allows gases to expand and contract. Gas atoms bounce around, and will not hold a form or stay together.
