Mazyrski [523]

Answer: The correct answer is Heterogeneous mixture

Explanation:

Heterogeneous mixture are those mixture in which:

  • Substance is distributed in non uniform manner.
  • Two distinct layers are formed

Thus when water and dirt are mixed together it results in the formation of  a heterogeneous mixture and after sometimes two different layers will be observed.

Hence, in the bottle there is a heterogeneous mixture of water and dirt.

What volume of a 0.33-M C12H22O11 solution can be diluted to prepare 25 mL of a solution with a concentration of 0.025 M?
Vsevolod [243]

The dilution formula can be used to find the volume needed

c1v1 = c2v2

Where c1 is concentration and v1 is volume of the concentrated solution

And c2 is concentration and v2 is volume of the diluted solution to be prepared

c1 - 0.33 M

c2 - 0.025 M

v2 - 25 mL

Substituting these values in the equation

0.33 M x v1 = 0.025 M x 25 mL

v1 = 1.89 mL

Therefore 1.89 mL of the 0.33 M solution needs to be diluted up to 25 mL to make a 0.025 M solution

Which of the following is defined as the mass of an atom based on the mass of an atom of carbon-12?
iogann1982 [59]
<span>This would be the atomic mass. In an atom of carbon-12, there are 6 protons and 6 neutrons at rest (electrons have a negligible mass and are usually not part of the overall mass calculation). All atomic masses are based off the measurements of this specific iteration of carbon.</span>
