Brownian motion is

Chemistry
1 answer:
ioda4 years ago
6 0

Answer: A.

Explanation:

Brownian motion is the random motion of a particle as a result of collisions with surrounding gaseous molecules. Diffusiophoresis is the movement of a group of particles induced by a concentration gradient. This movement always flows from areas of high concentration to areas of low concentration.

Example:  The movement of pollen grains on still water. Motion of dust motes in a room (though largely influenced by air currents).

What is the definition of DNA in meiosis
mario62 [17]
Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell. Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes!

A closed, nonreactive system contains species Aand Bin vapor/liquid equilibrium. Species Ais a very light gas, essentially insol
musickatia [10]

Answer:

Remain unchanged.

Explanation:

The total number of moles of liquid remain unchanged as the some moles of species B are added to the system because specie B that is added in the liquid phase is again restored after addition. If the specie B did not restored after addition to the liquid phase so the total number of moles increases in the liquid phase so that's why we can say that the liquid phase remain unchanged.

Find the mass in grams of 5.34 *10^20 atoms of carbon molar mass 12g
emmasim [6.3K]

0.01068‬g

Explanation:

Given parameters :

Number of atoms = 5.34 x 10²⁰ atoms

Molar mass of carbon = 12g

Unknown:

Mass of carbon = ?

Solution:

A mole of a substance is unit that contains the Avogadro's number of particles.

   1 mole = 6.02 x 10²³ atoms ;

 In  5.34 x 10²⁰ ;

   Number of moles = \frac{5.34 x 10^{20} }{6.02 x 10^{23} }  = 8.9 x 10⁻⁴moles

Mass = number of moles  x molar mass = 8.9 x 10⁻⁴ x 12 = 0.01068‬g
