To make a solution of lemonade, lemon juice and sugar are dissolved in water. the water is the <u>Solvent </u>in this example.

Solvent Examples. Common examples of solvents consist of water, ethanol, methanol, and acetone. The term 'solvent' may be defined as a substance that has the ability to dissolve a given solute to form a solution with it.

Solvents are substances that are used to dissolve the solutes used in the formulation. These solutes can be solids, liquids, or gaseous in nature. Thus solvents are used to get a solution upon interacting the solute with a suitable solvent.

Solvents are usually, however not usually, liquids. They can also be gases or solids. The material dissolved in the solvent is referred to as the solute. collectively, the solvent and solute comprise the solution.

Particles of Substance X are dispersed in water to form a colloid. Which describes the electrical charges on the particles of Su

Novay_Z [31]

The correct answer is option A.

All the particles carry the same charge, which could be either positive or negative.

All the particles of substance X will have same charge on its surface, which is balanced by the oppositely charged ions in the water.

For example, soap solution (sodium palmitate) dissociates into ions:

C₁₅H₁₁COONa --> C₁₅H₁₁COO⁻ + Na⁺

The cations (Na⁺) passes into the water while the anions (C₁₅H₁₁COO⁻) form aggregates or colloids.

#1: How are the elements arranged in the modern periodic table?

Alekssandra [29.7K]

1- The correct answer is C :

the elements arranged in the modern periodic table by increasing atomic number.

The explanation:

-The elements in the periodic table are arranged to increase the atomic number. All of these elements display several other trends and we can use the periodic law and table formation to predict their chemical, physical, and atomic properties.

2- The correct answer is C:

strontium, magnesium, calcium, beryllium are the elements which have similar properties.

The explanation:

-strontium, magnesium, calcium, beryllium, these belong to the alkaline earth metal group.

Because the outer electron structure in all of these elements is similar, they all have somewhat similar chemical and physical properties .

3- The correct answer is A :

Potassium

The explanation:

-The elements potassium and sodium have similar chemical properties because they have the same number of valence electrons and form +1 ions.

4- The correct answer is D

The explanation:

Mendeleev didn't include helium, neon, and argon in his periodic table because these elements had not yet been discovered.

5- The correct answer is B:

The periodic law describes trends seen across periods within the periodic table.

The explanation:

When the chemical elements are arranged, there is a pattern called the “periodic law” in their properties, in which elements in the same column (group) have similar properties

I’m learning about heredity

Morgarella [4.7K]

Answer:

1. (See explanation)

2. 46. 23 from the mother’s egg and 23 from the father’s sperm.

Explanation:

ok for number one I am not entirely sure, but I am pretty sure that light, chemicals and temperature can all affect which genes get turned on and off. I am not entirely sure if the question is asking about the environment influencing inherited traits in the form of natural selection tho? If that is something you’re seeing right now, it might be a possible answer. But honestly I am not completely sure.

Suppose 'A' is a liquid aromatic compound with molecular weight 78 and burns with sooty flame. a.Give the name of the compound '

Oliga [24]

Aromatic compounds are compounds that contain carbon-carbon multiple bonds.

The question did not mention that a heteroatom is present in the compound so we can assume that there is none of such. In that case, the compound contains only hydrogen and carbon.

So,

(CH)n = 78

where n is the number of each atom present.

(12 +1)n = 78

n = 78/13

n = 6

The molecular formula of the compound is C6H6

When C6H6 is treated with .conc.HNO3/conc.H2SO4 the compound shown in image 1 is formed. The reaction occurs at the C-C multiple bond.

When C6H6 is reacted with chlorine in the presence of sunlight, hexachlorobenzene (shown in image 2 attached) is formed.
