A molecular compound is defined as a molecule whose formula states the actual number of atoms bonded together in the molecule.

The atoms are joined to give a definite shape which is defined by the angles between the bonds and by the bond lengths. Molecular compounds can contain discrete molecules, which are held together by sharing electrons in covalent bonding.

Examples of molecular compounds are water, which contains H2O molecules; methane contains CH4 molecules; and hydrogen fluoride, which contains HF molecules.

As a rule of thumb, compounds that are involved in a metal binding with either a non-metal or a semi-metal will display ionic bonding.

Compounds can be composed with only non-metals or semi-metals and non-metals will display covalent bonding and will be classified as molecular compounds.

The number of moles of C₃H₈ that must be consumed via the given reaction is 0.168 mole

We'll begin by obtaining the mole of CO₂ produced. Details below:

PV = nRT

3.68 × 4 = n × 0.0821 × 355

Divide both sides by (0.0821 × 355)

n = (3.68 × 4) / (0.0821 × 355)

n = 0.505 mole

Finally, we shall determine the mole of C₃H₈ consumed by the reaction. This is illustrated below:

C₃H₈ + 5O₂ -> 3CO₂ + 4H₂O

From the balanced equation above,

3 moles of CO₂ were obtained from 1 mole of C₃H₈

Therefore,

0.505 mole of CO₂ will be obtained from = (0.505 × 1) / 3 = 0.168 mole of C₃H₈

Thus, number of mole of C₃H₈ consumed is 0.168 mole

The statement c. This change exposes more reactant particles to a possible collision explains why the speed of some chemical reactions is increased when the surface area of the reactant is increased.

The surface area of a reactant is directly related to the speed of a chemical reaction because as the surface area increases, the speed also increases due to the larger surface area allowing more particles to come into contact.

Therefore, with this data, we can see that the speed of a chemical reaction is directly proportional to the surface area of its reactants.

The law of definite proportions states that regardless of the amount of reactants used, a chemical reaction will always produce the same proportion of products. In this case, both reactions will produce the same mole ratio of PCL3 (1:1) even though they produce different numbers of moles of the product. To demonstrate this, let's take a look at the first reaction:

Reaction 1:

2HCl + Ca3(PO4)2 → 2CaCl2 + PCl3

2 moles of HCl + 1 mole of Ca3(PO4)2 → 2 moles of CaCl2 + 1 mole of PCl3

Therefore, the mole ratio of PCL3 is 1:1.

Now let's look at the second reaction:

Reaction 2:

HCl + P4O10 → PCl3 + H3PO4

1 mole of HCl + 2 moles of P4O10 → 1 mole of PCl3 + 2 moles of H3PO4

Once again, the mole ratio of PCL3 is still 1:1. Therefore, both of these chemical reactions obey the law of definite proportions.

What is the ideal room temperature?

Generally speaking, room temperature refers to a range of air temperatures that people favour indoors. When someone is dressed in regular indoor attire, they feel at ease. Depending on humidity, air circulation, and other factors, human comfort can go beyond this range.

Around 20°C, or 68° Fahrenheit, is usually the standard room temperature. Though it's crucial to keep in mind that different rooms will need to be heated to different temperatures, this is a good ambient temperature to aim for.

Store at 15°-25°C (59°-77°F) above room temperature. Ambient temperature: Keep your items at the temperature outside. Considering the vast range of ambient temperatures, this word is not commonly used.

Molecules with the stronger intermolecular forces are pulled tightly together  to form solid at higher temperatures and that's why the freezing point is higher.

Also, molecules with the stronger intermolecular force have greater interaction between the molecules and thus on heating do not boil easily and have high boiling point also.

Thus, melting point and boiling point increases with increase in number of carbon atoms and also increase in intermolecular forces (like hydrogen bonding, if present).

Thus, the compound which is gas at room temperature is  because it has least number of carbon atoms and absence of hydrogen bonding.

Solvents affect the polymers in way that they affect the strength of non-bonding interactions, which in return control the formation of supramolecular polymers in solution.

Solvents affect the polymers in way that they affect the strength of non-bonding interactions, which in return control the formation of supramolecular polymers in solution. Solvent effects and implications/parameters measured in supramolecular polymer systems are selectively reviewed. A rather new solvent scale, solvation ability (SA), which is based on the balance point between extended and stacked polymers is then introduced.

One of the most common processes used to produce polymer nanoparticles, is the solvent-displacement method, wherein the polymer is first dissolved in a "good" solvent and then the solution is mixed with an "anti-solvent". The processability of the polymer is therefore determined by polymer's structural and transporting properties in solutions of pure solvents and at the intermediate compositions.

If we put a polymer molecule into a pure solvent, three things might happen to it.

-it might curl up on itself

-it might not really notice/react with the solvent

-it might prefer the solvent used, to itself, and stretch out.

Molarity is a unit of measure used to indicate the concentration of a solute in a solution. It is expressed in moles of solute per liter of solution (mol/L). This measure is useful for describing the amount of a particular chemical species present in a solution, as well as for determining the amount of a reactant or product that is produced in a chemical reaction. Molarity is also used to calculate the amount of a substance that must be added to a solution to achieve a desired concentration.

The number of liters of a 0.26 M solution of Na₂MnO4 that would contain 0.38 mole of Na₂MnO4 can be calculated using the following equation:
