Why do gases diffuse more quickly than liquids?

Choose the correct answer.

A) Liquids can be compressed easily.

B)The particles in gases are not mobile.

C)Liquids are always at lower temperatures than gases.

D)Gas particles move rapidly and have space between them.

Answers

Answer:

D)Gas particles move rapidly and have space between them.

Explanation:

Matter exists in three states namely: solids, liquids and gases. The particles contained in these three states are different from one another. In the gaseous state, the particles are FAR APART from one another i.e. space exists and they move at a very fast rate in contrast to the particles of a liquid, which have less space and move slower.

This rapid movement of gas particles within a less restricted space accounts for the reason why gaseous substances DIFFUSE more quickly than liquids.

Given the two half-reactions, what must be done in the next step before the reaction can be balanced?

Answer: Show the number of electrons being lost or grained.

Explanation:

For a two given half-reactions, before the reaction can be balanced determine the number of electrons being lost or grained.

What is a half-reaction?

A half reaction is either the oxidation or reduction reaction component of a redox reaction.

The half reaction is obtained by considering the change in oxidation states of individual substances involved in the redox reaction.

Thus, for a two given half-reactions, before the reaction can be balanced determine the number of electrons being lost or grained.

Which diagram best shows the field lines around two particles with opposite
charges?

Answers

The diagram best shows the field lines around two particles with opposite charges is the third diagram. Therefore, option C is correct.

What is field line ?

A graphic tool for viewing vector fields is a field line. It is made up of a fictitious directed line that is perpendicular to the field vector over its whole length.

Among many other sorts, they are employed to display magnetic, electric, and gravitational fields. In the study of fluid mechanics, streamlines are field lines that display the velocity field of a fluid flow.

The field lines are parallel to the charge's surface. Both the size of the charge and the quantity of field lines are proportional. The positive charge is where the field lines begin, and the negative charge is where they come to a conclusion.

Thus, option C is correct.

What is periodic table?

Periodic table is defined as a table with the chemical elements ordered by increasing atomic number, displaying the elements to show trends in their characteristics. The elements are arranged in the Periodic Table in accordance with their related chemical and physical characteristics. There are rows and columns in the table. The periodic table's vertical columns stand in for Groups. Periods are shown in the table as horizontal rows.

Ions are defined as any atom or collection of atoms that carries one or more electrical charges, either positive or negative. The positive ions are known as cation while the negative ions are known as anion. When an atom's number of protons and electrons is out of balance, ions are created.

Thus, one ion is represented in each block of the periodic tables. Hence option C is correct.

A sample of 87.6 g of carbon is reacted with 136 g of
fluorine gas to produce carbon tetrafluoride. Using
the balanced equation below, predict which is the
limiting reactant and the maximum amount in moles
of carbon tetrafluoride that can be produced.
C +2F2 → CF4
A. fluorine, 1.79 moles
B. carbon, 7.29 moles
C. fluorine, 6.72 moles
D. carbon, 4.63 moles

Answers

Answer:

A. fluorine, 1.79 moles

Explanation:

Given parameters:

Mass of carbon  = 87.7g

Mass of fluorine gas  = 136g

Unknown:

The limiting reactant and the maximum amount of moles of carbon tetrafluoride that can be produced  = ?

Solution:

   Equation of the reaction:

             C    +   2F₂ →   CF₄  

let us find the number of the moles the given species;

  Number of moles = [tex]\frac{mass}{molar mass}[/tex]  

  C;   molar mass = 12;

            Number of moles  = [tex]\frac{87.7}{12}[/tex]   = 7.31moles

 F;  molar mass  = 2(19)  = 38g/mol

             Number of moles  = [tex]\frac{136}{38}[/tex]   = 3.58moles

 So;

   From the give reaction:

          1 mole of C requires 2 moles of F₂

         7.31 moles of C will then require 2 x 7.31 moles of F₂ = 14.62moles

But we have 3.58 moles of the F₂;

  Therefore, the reactant in short supply is F₂ and it is the limiting reactant;

 So;

       2 moles of F₂ will produce  mole of CF₄  

       3.58 moles of F₂ will then produce [tex]\frac{3.58}{2}[/tex]  = 1.79moles of CF₄

What is the final concentration of a solution prepared by diluting 35.0 mL of 12.0 M HCl to a final volume of 1.20 L

Answers

Answer: The final concentration of a solution is 0.350 M

Explanation:

According to the dilution law,

[tex]C_1V_1=C_2V_2[/tex]

where,

[tex]C_1[/tex] = concentration of concentrated acid solution = 12.0 M

[tex]V_1[/tex] = volume of concentrated acid solution = 35.0 ml

[tex]C_2[/tex] = concentration of diluted acid solution= ?

[tex]V_2[/tex] = volume of another acid solution= 1.20 L = 1200 ml

( 1L=1000ml)

Putting in the values:

[tex]12.0\times 35.0=C_2\times 1200[/tex]

[tex]C_2=0.350M[/tex]

The final concentration of a solution prepared by diluting 35.0 mL of 12.0 M HCl to a final volume of 1.20 L is 0.350 M

Explanation:

my teacher asked the same question but with  diffrent oppstions.

and diffusion is DEFINATALY not the answer. its convection.  

Molecules of air in direct contact with Earth's solid, warm surface absorb heat energy with conduction.

What is conduction ?

The process by which heat is transmitted from an object's hotter end to its cooler end is known as conduction. The term "thermal conductivity" refers to an object's capacity to transfer heat, and it is represented by the letter k. Along a temperature gradient, heat flows naturally.

When two materials or objects come into direct touch with one another, conduction takes place. More quickly than in a cooler item, the molecules in a warmer one vibrate. The slower molecules clash with the faster vibrating molecules.

Ground-level heat is radiated into the lower atmosphere. In conduction, heat is transferred directly from hotter regions to cooler ones. Warmer molecules bounce vigorously and clash with molecules close by, exchanging energy.

Thus, option A is correct.

If plants do not receive enough light, they will not grow at their maximum rate or reach their maximum potential, regardless of how much of any other variable – water, growth medium or fertiliser – they receive. Light is the driving force for photosynthesis, a plant process that changes sunlight into chemical energy.

Which explanation accounts for why carbon monoxide is not a polar molecule?

The electronegativity differences between carbon and oxygen are not very large.

Carbon and oxygen do not form ions.

Carbon is a metal, and oxygen is a nonmetal.

There are no hydrogen atoms in the molecule.

Answers

Answer:

The electronegativity differences between carbon and oxygen are not very large.

Explanation:

Between the atoms of carbon monoxide exists a covalent bond which attaches the carbon to the oxygen.

In this type of bonding, both atoms shares a given number of valence electrons to attain chemical stability.

A substance is polar when there is a distinct charge separation between the species.

For covalent bonds, the electronegativity difference plays in important role in determining the polarity of the compound. When the difference is large, the compound will be polar but when the difference is very small or zero, no polarity will exist.

In between carbon and oxygen of carbon monoxide, the electronegativity difference is very low.

Chemistry is the study of matter, which is anything that has mass and takes up spaces. Changes in matter is best described as physical properties, can be observed without changing the substance into another substance, and chemical properties, a substance that describes it's ability to change into other substances. An example of a physical property is melting point and flexibility. An example of a chemical property is burning and rusting.

Chemical changes may also occur when bonds break and new bonds are then formed. As a result of this, a new substance is formed. Something you can look for in physical properties are changes in color and if gases are produced from solids or liquids.

chemistry is the science of changing of objects into other substances, and the study of matter. Chemical change can be seen with things like irreversable burns, and cooking while physical change can be seen as changes of apperance like moving an object, or painting it.
