What happens when the concentration of water inside a cell is lower than the concentration of water outside the cell?
adell [148]

Answer:

Water outside the cell will flow inwards by osmosis to attain equilibrium

Explanation:

In the hypotonic environment, the concentration of water is greater outside the cell and the concentration of solute is higher inside. A solution outside of a cell has a lower concentration of solutes relative to the cytosol.

If concentrations of dissolved solutes are greater inside the cell, the concentration of water inside the cell is correspondingly lower. As a result, water outside the cell will flow inwards by osmosis to attain equilibrium.

Osmosis is a process by which molecules of a solvent tend to pass from a less concentrated solution into a more concentrated one through a semipermeable membrane.

A 1.10 mol sample of krypton gas is collected at a pressure of 427 mmHg and a temperature of 6.0°C. The volume of the sample is
Aleksandr [31]

Answer:

Volume = 44.96L

Explanation:

p = 427mmHg = 0.56atm

R = 0.08206

T 6°C = 279k

V = ?

n = 1.10 mol

using ideal gas equation

pv=nRT

0.56 x V = 1.10 x 0.08206 x 279

0.56 x V = 25.18

V = 25.18/0.56

V = 44.96L

If wave A has a frequency of 4.60 x 10^14 s-1, what is the wavelength in nanometers (show your work)?
victus00 [196]

Answer:

652.174nm

Explanation:

We need to know that the speed of light never changes. It has a value of 3 × 10^8 m/s.

Given only the frequency, we can find the wavelength by dividing the value of the speed of light by the value of the frequency.

That equals = (3 × 10^8) ÷ ( 4.6 × 10^14) = 0.000000652174 m = 652.174 ÷ 10^-9m = 652.174nm
