Why does an ionic bond transfer electrons instead of sharing?

Chemistry
1 answer:
saveliy_v [14]3 years ago
3 0
The modern definition of electronegativity is due to Linus Pauling. It is the power of an atom in a molecule to attract electrons to itself.

When the electronegativity difference between the two atoms is greater than 2.0, the bond is considered ionic; i.e. there is complete transfer (between the two atoms) of the electrons in the bond. The electronegativity (according to Pauling scale) of chlorine is 3.0, while the electronegativity of sodium is 0.9.

So, electrons are transferred because of a larger electronegativity difference.

Which chemical process generates the atp produced in glycolysis?.
Naddik [55]

Atp is a form of energy and it is generated through a chemical process called substrate level phosphorylation.

<h3 /><h3>What is substrate level phosphorylation?</h3>

Substrate-level phosphorylation is a reaction that makes use of substrate to generate Adenosine triphosphate (ATP) which is a form of energy.

ATP is produced through the transfer of phosphate group from the substrate directly to adenosine diphosphate (ADP).

Therefore, substrate-level phosphorylation generates the atp produced in glycolysis.

A chemistry student needs 60.0 ml of ethanolamine for an experiment. By consulting the CRC Handbook of Chemistry and Physics, th
BARSIC [14]

Answer:

The student should weigh out 61.2g of ethanolamine [6.12 * 10]

Explanation:

In this question, we are expected to calculate the mass of ethanolamine needed to make 60.0ml of it given that the density of the ethanolamine in question is 1.02g/cm^3

Mathematically, it has been shown that mass = density * volume

Hence, by multiplying the density by the volume, we get the mass.

Now, from the question we can see that we have the values for the density and the volume. We now need to get the mass.

Since cm^3 is same as ml, we need not perform any conversion.

Hence, the needed mass is:

60 * 1.02 = 61.2g

The combustion of 44.45 grams of a hydrocarbon gas mixture releases 2,649 kJ of heat. How much energy, in kWh, will the combusti
Naddika [18.5K]

Explanation:

It is given that 44.45 g of hydrocarbon gas produces 2649 kJ or 2649 \times 10^{3} J of heat.

Also here, 1 lb = 453.592 g.

Therefore, amount of energy released by 453.592 g of hydrocarbon gas will be calculated as follows.

              \frac{2649 \times 10^{3} J \times 453.592 g}{44.45 g}

             = 27.03 \times 10^{6} J

It is known that 1 J = 2.778 \times 10^{-7} Kwh.

Hence, 27.03 \times 10^{6} J = 27.03 \times 10^{6} J \times 2.778 \times 10^{-7} Kwh/J

                              = 7.508 Kwh

Thus, we can conclude that the combustion of exactly one pound of this hydrocarbon gas produce 7.508 Kwh energy.

What is the difference between traits and characteristics?
Katena32 [7]

A Characteristic is the unique assets, talents, and qualities of a person. On the other hand, a trait is a feature of a person that is hereditary or inherited from parents or offspring. The characteristics are usually something that a person can learn and built by absorption, a trait, on the other hand, is something you have since birth.

Rank these photons in terms of increasing energy:<br> (a) blue (λ=453nm)
alexira [117]

The increasing order of photons in terms of energy is Er < Ey < Eb

A photon is a tiny particle of electromagnetic radiation and its energy is proportional to the frequency and rest mass as zero.

By using the formula:

E = h * ν

E = h * c / λ

h = planks constant

c = speed of light

Since h * c is constant

E is inversely proportional to wavelength  λ

For blue:

λ = 453 nm

Eb= k / 453

where k is constant

For red:

λ = 660 nm

Er = k / 660

For yellow:

λ = 595 nm

Ey = k / 595

Therefore,

The increasing order of photons in terms of energy is

Er < Ey < Eb.
