Answer:  Tyndall effect

Explanation:

Colloids are defined as the mixtures where the size of the particle is within the range of 2nm to 1000 nm. In these mixtures, physical boundary is seen between the dispersed phase and dispersed medium.

Tyndall effect is defined as the effect in which scattering of light takes place by the particles present in a colloid or in very fine suspension.  For Example: Scattering of sunlight by clouds

Brownian motion is the movement of finely suspended colloidal particles due to collisions.

Mohs is a scale used to determine the hardness of materials

Faraday is a law which states that the mass of the substance deposited at any electrode is directly proportional to the quantity of electricity or charge passed.

mamaluj [8]

Answer:

A

Explanation:

Isomerism is a phenomena whereby two or more organic compounds have the same molecular formula but different structural arrangements.

This means the organic compounds may belong to different organic family but the main idea is that they have different structural and spatial arrangements but the same molecular formula. This means they have the same number of each atoms

Use the portion of the periodic table shown below to answer the questions.
Bingel [31]

The two elements that have the same properties as sodium are potassium  and rubidium .

<h3>What is periodic table?</h3>

The periodic table is an arrangement of the elements in order of increasing atomic number.

From the list, the two elements that have the same properties as sodium are potassium  and rubidium .

Proton has an atomic number of 20 and a mass number of 40. The number of electrons is the same as the number of protons. Given that the atomic number is the number of protons present, we have 20 electrons and 20 protons.

Number of neutrons = Mass number  - Number of protons

= 40 - 20 = 20 neutrons

Pls help asap!!!!
AVprozaik [17]

Answer: The pressure of the He is 2.97 atm

Explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

p_{total}=p_{N_2}+p_{O_2}+p_{He}.

Given : p_{total} =total pressure of gases = 6.50 atm

p_{N_2} = partial pressure of Nitrogen = 1.23 atm

p_{O_2} = partial pressure of oxygen = 2.3 atm

p_{He} = partial pressure of Helium = ?

putting in the values we get:

6.50atm=1.23atm+2.3atm+p_{He}  

p_{He}=2.97atm

The pressure of the He is 2.97 atm
