Diamond has a macromolecular structure and iodine is a simple covalent molecule. Use your knowledge of structure and bonding to explain why diamond has a higher melting point than iodine.

Answers

Answer:

Diamond is covalently bonded and has a giant covalent structure. Covalent bonds require lots of energy to break as they are strong so diamond has the highest melting point. Iodine has only weak intermolecular forces (instantaneous dipole-dipole interactions or London forces) whereas hydrogen fluoride has a permanent dipole and can hydrogen bond (as well as having London forces).

The role played by hydraulic fluid in a hydraulic machine is as a medium for

the transfer of force.

Hydraulic fluid is used primarily in a hydraulic machine for the transfer of

force from one point to another. This makes the system able to perform the

required functions.

Hydraulic fluid also has other functions such as being a coolant and as a

cleaning agent(removal of contaminants) which aren't its major function.

reaction if 0.7525 moles of oxygen gas (O2) are consumed.

Answers

Answer:

4.530 X 10^23 MOLECULES OF CO2

Explanation:

Calculate the number of carbon dioxide (CO2) molecules produced in the

reaction if 0.7525 moles of oxygen gas (O2) are consumed

so

C + O2-----------CO2

1 MOLE OF 02 produces 1 mole of CO2

so

0.7525 moles O2 produce 0.7525 moles

1 mole is 6.02 X 10^23

so

0.7525 moles is 0.7525 X 6.02 X 10^23 -

=

How do atomic and molecular interactions explain the properties of matter that we see and feel

Answers

The atomic and molecular interactions unveil the bulk properties of matter in our environment by ways of the fact that everything in the whole universe is made of either atoms, molecules or even ions

How matter is made up of atoms and molecules?

It has been proven practically everything in the whole universe is matter and everything which interact with matter is also matter. This explains to us the reasons why matter could be atoms, molecules or ions.

That being said, some substances (matter) is made up of atoms of elements, some made up of molecules or atoms and molecules and others ions or both. However, matter is anything which has mass and occupies space.

In conclusion, we can now conclude from the explanation above that the properties of matter are as a result of the interaction which exists between matter at the atomic and molecular level.

There are two modes in which unstable nuclei of radioactive elements may decay. They are by α - emission or by β - emission. Among the given options, the α - emission is ₆₄¹⁴⁸Gd → ₆₂¹⁴⁴Sm + ₂⁴He. The correct option is D.

What is α - decay?

According to the theory of radioactive disintegration, the atoms of all the radioactive elements undergo spontaneous disintegration with the emission of α or β particles to yield atoms of new elements. When a radionuclide decays by emitting an  α - particle, it is called α - decay.

When a radionuclide undergoes  α - emission, i.e. a helium nucleus there occurs a decrease of 2 units in the atomic number and a decrease of 4 units in the mass number. The new nuclide produced has an atomic number 2 units less and a mass number 4 units less than the parent.

₆₄¹⁴⁸Gd → ₆₂¹⁴⁴Sm + ₂⁴He represents α - emission.

Thus the correct option is D.

HELP QUICK carbon dioxide makes up less than 1 percent of earths atmosphere, and oxygen makes about about 20 % These percentages are maintained most directly by what

Answers

Answer:

respiration and photosynthesis

Explanation:

The percentages of carbon dioxide and oxygen in Earth's atmosphere are maintained most directly by cellular respiration and photosynthesis.

What is photosynthesis?

Photosynthesis simply refers to a biological and chemical process through which green plants convert light energy derived from the Sun into chemical energy, so as to make their food while using carbon dioxide (CO₂) and releasing oxygen.

On the other hand, cellular respiration is a series of metabolic reactions that occur in living cells and it involves the use of oxygen that are typically produced by green plants (autotrophs) during photosynthesis.

This ultimately implies that, the percentages of carbon dioxide (1%) and oxygen (20%) that are contained in Earth's atmosphere are maintained most directly by cellular respiration and photosynthesis.

Assume that the heat lost by the surface is gained by ethyl chloride. What enthalpies must you consider if you were to calculate the final temperature of the surface

Answers

Answer:

Specific heat of ethyl chloride in gas and liquid phases, enthalpy of vaporization and specific heat of solid surface.

Explanation:

In order to determine the final temperature, the heat lost by the chloride needs to be found. This would require the specific heat in both phases and the enthalpy of vaporization. (you will use q=mc(delta)T and q=m(delta)H)

Then the energy gained by the surface needs to be found. This will require the specific heat in order to use the q=mc(delta)T equation.

The enthalpies that we consider to calculate the final temperature of the surface are Specific heat of surface and ethyl chloride as well as Heat of vaporization of liquid & vapor ethyl chloride.

What is enthalpy?

Enthalpy of any reaction tells about the total amount of heat absrobed and released during a chemical reaction.

According to the question, heat released by the surface is absorbed by the ethyl chloride and by absorbing this energy ethyl chlorode will change into the vapor form. In the whole process if we want ot calculate the final temperature on the surface then we should consider:

Specific heat of surface.Specific heat of ethyl chloride.Heat of vaporization of liquid ethyl chloride.Heat of vaporization of vapor ethyl chloride

Hence, required enthalpies are Specific heat of surface and ethyl chloride as well as Heat of vaporization of liquid & vapor ethyl chloride.

Answer:

Gas>Liquid>Solid

Explanation:

Entropy by definition is the degree of randomness in a system. If we look at the three states of matter: Solid, Liquid and Gas, we can see that the gas particles move freely and therefore, the degree of randomness is the highest.

As the reaction goes through phases, the phase that has the highest entropy is the gas state. This is further explained below. Option A is correct.

What is entropy?

A thermodynamic number that represents the inability of a system's thermal energy to be converted into mechanical work, and is commonly understood as the system's degree of disorder.

In conclusion, we have that as the reaction goes through phases, the gaseous state has the highest entropy.

Calculate the pH at the equivalence point for the following titration: 0.25 M HCOOH versus 0.25 M NaOH.

Answers

The pH at the equivalence point for the titration of 0.25 M HCOOH versus 0.25 M NaOH is 8.5.

Let's consider the following neutralization reaction.

HCOOH + NaOH ⇒ HCOONa + H₂O

At the equivalence point, 0.25 M HCOOH completely reacted with 0.25 M NaOH to form 0.25 M HCOONa.

HCOONa undergoes hydrolysis. The net ionic equation is:

HCOO⁻(aq) + H₂O(l) ⇄ HCOOH(aq) + OH⁻(aq)

Given the concentration of HCOO⁻ is 0.25 M (Cb) and the basic dissociation constant of HCOO⁻ is 4.8 × 10⁻¹¹ (Kb), we can calculate the concentration of OH⁻ using the following expression.

[tex][OH^{-} ] = \sqrt{Kb \times Cb } = \sqrt{(4.8 \times 10^{-11} ) \times 0.25 } = 3.5 \times 10^{-6} M[/tex]

The pOH of the solution is:

[tex]pOH = -log [OH^{-} ] = -log (3.5 \times 10^{-6} ) = 5.5[/tex]

The pH of the solution is:

[tex]pH = 14 -pOH = 14 -5.5 = 8.5[/tex]

The pH at the equivalence point for the titration of 0.25 M HCOOH versus 0.25 M NaOH is 8.5.

The volume of a ballon is 2.85L at 1.00 atm. What pressure is required to compress the balloon to a volume of 1.70L?

Answers

Answer:

1.68 atm (if temperature is constant)

Explanation:

p1 * v1 = p2 * v2

1 * 2.85 = p2 * 1.70

2.85 / 1.70 = p2

p2 = 1.6764

There are so many gas laws like Charles's law, Avogadro’s law and many more, out of which Boyle's law is one of the most important law among all gas laws. The pressure is required to compress the balloon to a volume of 1.70L is  1.6764 atm.

What is Boyle's law?

According to Boyle's law pressure is inversely proportional to volume at constant Temperature. It is applicable only on the ideal gases. Since temperature is constant here, we can apply this law.

Mathematically

P₁V₁=P₂V ₂

P₁= initial pressure of balloon =1.0atm

V₁= initial volume balloon =2.85L

P₂=final pressure balloon =?

V ₂=final volume balloon =1.70L

Putting all values

1 × 2.85 = P₂×1.70

2.85÷ 1.70 = P₂

P₂ = 1.6764 atm

Therefore, the pressure is required to compress the balloon to a volume of 1.70L is 1.6764 atm.
