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.

Explanation:

The force stopping the object's motion might be an obvious one - the ground! Friction is a force that slows or stops motion. Friction is the resistance to motion created by two objects rubbing against each other (the sled and the snow, for instance). Even air causes friction.

Answer:

Option 1

Explanation:

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.

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.

Explanation:

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

Answer:

The volume of a gas is directly proportional to its temperature. Avagadro's Law- Gives the relationship between volume and amount of gas in moles when pressure and temperature are held constant. If the amount of gas in a container is increased, the volume increases.

Answer:

actually its c convection.

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: 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

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.
