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.

Explanation:

well I'm not 100% sure but I studied a little bit with rocks and crystals I've noticed that the hotter the temperature are it does not matter if it is Obsidian the hotter it is the more shinier it will become so the texture of it has to be a right temperature to be able to create a different texture such as a diamond and a diamond has to be compressed so hard that it will turn into diamond this is just an explanation please do not take this as a real answer I hope this help you though

One ion is represented in each block of the periodic tables. Hence option C is correct.

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.

Answer:

If some of the stearic-acid hexane solution had evaporated before using it, this would increase Avogadro's number, or the number of atoms per mole. This is because with less hexane in the solution (because only the hexane evaporates), the grams of stearic acid used would be smaller.

Explanation:

If some of the stearic-acid hexane solution evaporated before using it, this would increase Avogadro's number or the number of atoms per mole. This is because grams of stearic acid used would be smaller, with less hexane in the solution .

Proportionality factor that relates number of constituent particles in a sample with the amount of substance in that sample is called Avogadro constant .

Avogadro's number is equal to 6.02214076 × 1023. The units can be electrons, atoms, ions, or molecules, depending on the nature of the substance and the character of the reaction .

Avogadro's law is used to for the relationship between the amount of gas and the volume . Volume of a gas is proportional to the number of moles in the gas sample as it's a direct relationship.

Answer:

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.

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.

Answer:

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.

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.

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

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.

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

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
