Based on the concentration of the solutions, the increase in volume is as follows:

  • the volume of the 20% (m/v) starch increases
  • the volume of the 10% (m/v) albumin increases
  • the volume of the 5% (m/v) sucrose increases

<h3>What is osmosis?</h3>

Osmosis is the movement of water molecules from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane.

The movement of water molecules in the solution pairs is as follows:

  • the volume of the 20% (m/v) starch increases because water moves in from the 10% (m/v) starch solution.
  • the volume of the 10% (m/v) albumin increases because water moves in from the 2% (m/v) albumin
  • the volume of the 5% (m/v) sucrose increases because water moves in from the 0.5% (m/v) sucrose.

Therefore, the increase in volume depends on the concentration ofvthe solutions.

Why is it important to know what temperature scale is being used in a given situation?
Arisa [49]
It depends, for example, it is quite important to know the Kelvin scale (i.e 0 degrees Celsius is 273 K and -273 degrees Celsius is 0 K ) when dealing gases. But I don't know other situations where you would need to know other temperature scales.

Hope this helps and also if you are using Fahrenheit 1 Fahrenheit is -17.22 degrees Celsius

Answer:

PART A: 412.98 nm

PART B: 524.92 nm

Explanation:

The equation below can be used for a diffraction grating of nth order image:

n*λ = d*sinθ_{n}

Therefore, for first order images, n = 1 and:

λ = d*sinθ_{1}.

The angle θ_{1} can be calculated as follow:

tan θ_{1}  = 9.95 cm/15.0 cm = 0.663 and

θ_{1} = tan^{-1} (0.663) = 33.56°

Thus: d =λ/sin θ_{1}  = 461/sin 33.56° = 833.97 nm

PART A:

For a position of 8.55 cm:  

tan θ_{1}  = 8.55 cm/15.0 cm = 0.57 and

θ_{1} = tan^{-1} (0.57) = 29.68°

Therefore:

λ =d*sin θ_{1}  = 833.97*sin 29.68° = 412.98 nm

PART B:

For a position of 12.15 cm:  

tan θ_{1}  = 12.15 cm/15.0 cm = 0.81 and

θ_{1} = tan^{-1} (0.81) = 39.01°

Therefore:

λ =d*sin θ_{1}  = 833.97*sin 39.01° = 524.92 nm

Does the mass of a ball affect how far it rolls
dybincka [34]
Yes, it depends on the size of the ball and the weight. If it's heavy and big then it'll affect how far it rolls, if it's small and has no weight then it won't really move as much

Which reaction may be described as an acid-base neutralization reaction? 1. be(oh)2 + h2so4 → beso4 + 2 h2o 2. ba(oh)2 + 2 licl
Svetradugi [14.3K]
 The reaction that describe an acid an acid- base neutralization reaction is

Be(OH)2 + H2SO4 = BeSO4 +2 H2O

Neutralization reaction involve an acid  and a base reaction whereby the acid  neutralization the base. for the reaction above Be(OH)2 is  the base while H2SO4 is the acid  thus H2SO4  neutralizes  Be(OH)2 to form BeSO4 and H2O
