Which of the following will occur if a prokaryotic cell is placed in a solution that has a higher concentration of solutes (that

cannot readily diffuse across the plasma membrane) than does the cytoplasm of the cell?

Answer:

This Question is incomplete

Explanation:

What is needed to be understood here is the concept of hypertonic and hypotonic solutions and their effects on cells.

Hypertonic solution is a solution in which the concentration of the solutes outside of the cell is greater than inside (in the cytoplasm) of the cell while hypotonic solution is a solution in which the concentration of solutes inside of the cell (in the cytoplasm) is greater than outside of the cell.

From the above, we can deduce that the question is about the effect of placing a prokaryotic cell in a hypertonic solution. When a prokaryotic cell is placed in a hypertonic solution, water moves (through osmosis) from inside of the cell to the outside environment causing the prokaryotic cell to shrink.

Which aqueous solution has the highest boiling point at standard pressure?(1) 1.0 M KC1(aq) (3) 2.0 M KCl(aq)(2) 1.0 M CaC12(aq)
miss Akunina [59]

Answer:

(4) 2.0 M CaCl₂(aq).

Explanation:

  • Adding solute to water elevates the boiling point.
  • The elevation in boiling point (ΔTb) can be calculated using the relation:

<em>ΔTb = i.Kb.m,</em>

where, ΔTb is the elevation in boiling point.

i is the van 't Hoff factor.

  • van 't Hoff factor is the ratio between the actual concentration of particles produced when the substance is dissolved and the concentration of a substance as calculated from its mass. For most non-electrolytes dissolved in water, the van 't Hoff factor is essentially 1.

Kb is the molal elevation constant of water.

m is the molality of the solution.

<u><em>(1) 1.0 M KCl(aq):</em></u>

i for KCl = no. of particles produced when the substance is dissolved/no. of original particle = 2/1 = 2.

suppose molarity = molality, m = 1.0 m,

∴ ΔTb for (1.0 M KCl) = i.Kb.m = (2)(Kb)(1.0 m) = 2(Kb).

<u><em>(2) 2.0 M KCl(aq):</em></u>

i for KCl = no. of particles produced when the substance is dissolved/no. of original particle = 2/1 = 2.

suppose molarity = molality, m = 2.0 m,

∴ ΔTb for (1.0 M KCl) = i.Kb.m = (2)(Kb)(2.0 m) = 4(Kb).

<u><em>(3) 1.0 M CaCl₂(aq):</em></u>

i for CaCl₂ = no. of particles produced when the substance is dissolved/no. of original particle = 3/1 = 3.

suppose molarity = molality, m = 1.0 m,

∴ ΔTb for (1.0 M KCl) = i.Kb.m = (3)(Kb)(1.0 m) = 3(Kb).

<u><em>(4) 2.0 M CaCl₂(aq):</em></u>

i for CaCl₂ = no. of particles produced when the substance is dissolved/no. of original particle = 3/1 = 3.

suppose molarity = molality, m = 2.0 m,

∴ ΔTb for (1.0 M KCl) = i.Kb.m = (3)(Kb)(2.0 m) = 6(Kb).

  • <em>So, the aqueous solution has the highest boiling point at standard pressure is: (4) 2.0 M CaCl₂(aq).</em>

The balanced equation for the generation of sugar from sunlight water and co2 is
asambeis [7]

The balanced equation for the generation of sugar from sunlight water and CO₂ is

6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂

carbon dioxide + water → sugar + oxygen

<span>The process of photosynthesis occurs when the chlorophyll present in the leaves of plants absorb sunlight to make food in the presence of carbon dioxide (enters through the stomata of leaves) and water (absorbed from the roots). As a result of this reaction sugar and oxygen is formed. After that sugar is converted in to starch and oxygen is released into air.</span>
