Answer: Option (a) is the correct answer.
Explanation:
A chair is a solid substance and it is known that particles in a solid are closely held together by strong intermolecular forces of attraction.
Therefore, solids are rigid and have a definite shape.
Thus, we can conclude that the chair in which you are currently sitting retain its same shape over time because the particles of the chair are strongly held together.
Density = mass / volume
Substitute
And is 7.80555 g/cm cube
Answer:
1.08 g/mL
Explanation:
Density=Mass/Volume therefore you would do the mass which is 7.481 g divided by the volume which is 6.9 mL and get 1.08 g/mL since you combine the two labels!
Answer:
B) The chromosomes in the cell lack a homologous pair in the same cell
Explanation:
Meiosis is the cellular division that reduces the chromosomal number of the parent cell by half in the daughter cells produced. In a somatic (body) human cell, chromosomes are found in homologous pairs i.e. each pair coming from each parent to form a diploid organism (2n).
However, when meiosis occurs, this homologous pair is separated into individual chromosomes. This is the case of the human cell which contains 46 chromosomes or 23 pairs of chromosomes. Each pair is an homolog of the other, however, meiotic division causes the homologs to separate. This will cause the chromosomes in the cell lack a homologous pair in the same cell.
Answer:
High
Explanation:
When the unknown compound contains an impurity that is insoluble in cyclohexane, the solute will not dissolve in the solvent (cyclohexane) completely. ∆T of the solution would be smaller than it is supposed to be, when compared to a compound without such insoluble impurity. Molecular weight determination won't be accurate because the molecular weight obtained will be higher as a result of the fact that the mass of the solute would include the actual solute that is changing the temperature and the excess mass of the impurity.
