how are compounds with metallic bonds similar to ionic compounds?

Answers

Answer 1

Answer:

Metals do not form double and triple bonds in general because metals want to lose electrons, not share, in order to become stable, and both compounds have high melting ppints

Answer 2

Compounds with metallic bonds and ionic compounds are similar in their melting point and boiling point, conductivity, solubility in polar solvents etc.

Ionic compounds are chemical compounds that are formed by the electrostatic attraction between oppositely charged ions.

Compounds with metallic bonds and ionic compounds are similar in several ways. Some of the similarities are:

1. High melting and boiling points: Both metallic and ionic compounds have high melting and boiling points due to the strong forces that hold the atoms or ions together.

2. Conductivity: Both metallic and ionic compounds are good conductors of electricity due to the presence of charged particles that can move freely.

3. Brittle: Ionic and metallic compounds are generally brittle in nature, meaning that they are prone to breaking or shattering when subjected to stress.

4. Solubility in polar solvents: Both metallic and ionic compounds are generally soluble in polar solvents such as water, due to the polar nature of the molecules.

In conclusion, compounds with metallic bonds and ionic compounds share several similarities. Both have high melting and boiling points, are good conductors of electricity, are brittle, and are generally soluble in polar solvents.

How would you expect a positive particle approaching another positive particle to behave?

Answers

Answer:

They would produce a repulsive force to another

Explanation:

A positive particle approaching another positive particle will repulse it.

According to coulomb's law "like charges repel one another and unlike charges attract".

A charge is an intrinsic property of any matter.

When like charges e.g positive and positive or negative and negative charges are in the vicinity of one another, they repel each other.

When unlike charges; positive and negative are brought together, they simply attract one another.

Therefore, we expect that a positive particle approaching another positive particle will repel one another.  

When a positive particle approaches another positive particle, the two particles repel or move away from each other.

In electrostatics we know that like charges repel while unlike charges attract. Therefore when we have two like charges, they simply move away from each other. This is known as repulsion of charges.

Hence, two positive charges approaching each other will simply move away and repel each other according to the laws of electrostatics.

A new element was discovered. It’s average atomic mass was found to be 245.6 amu. Isotope #1 has a mass of 243.2 amu; isotope #2 has a mass of 244.9 amu; isotope #3 has a mass of 247.2 amu. Which isotope is most likely to be the most abundant?

A
Isotope 1

B
Isotope 2

C
Isotope 3

D
They all contribute the same amount

Answers

Answer:

B. Isotope 2

Explanation:

Isotopes can be defined as the atom of an element that has the same number of protons but different number of neutrons. This ultimately implies that, the isotopes of an element have the same atomic number (number of protons) but different atomic mass (number of nucleons).

Basically, the atomic mass of any chemical element found in the periodic table is equal to the weighted average of all its isotopes. Therefore, the isotope with the closest mass to the weighted average would be the most abundant.

In this scenario, a new element was discovered with an average atomic mass of 245.6 amu.

Isotope #1 has a mass of 243.2 amu.Isotope #2 has a mass of 244.9 amu.Isotope #3 has a mass of 247.2 amu.

Hence, the isotope which is most likely to be the most abundant is isotope #2 that has a mass of 244.9 amu because it is closest in mass to the relative atomic mass (weighted average) of 245.6 amu.

As we will soon see in Section 4.5, gasoline is a complex mixture of alkanes and other hydrocarbons, and the term "octane rating" is used as a standard measure of the performance of engine fuel. In the petroleum industry, one area of interest is the use of catalysts to convert unbranched alkanes and branched alkanes with higher octane ratings (Journal of the Japan Petroleum Institute 2004, 47, 1–10). For example, heptane can undergo isomerization in the presence of suitable catalysts to give eight different constitutional isomers, all of which are branched alkanes with the molecular formula C7H16. Draw all eight constitutional isomers, making sure not to draw the same compound twice.

Answers

Answer:

Explanation:

C₇H₁₆ is heptane and it has nine isomers (n-heptane and the remaining 8 constitutional isomers). Constitutional isomers are compounds with the same molecular formula but different structural formula or atom connectivity.

The constitutional isomers of n-pentane are 2-methylhexane, 3-methylhexane, 2,2-dimethylpentane, 2,3-dimethylpentane, 2,4-dimethylpentane, 3,3-dimethylpentane, 3-ethylpentane and 2,2,3-trimethylbutane. There structures are in the picture attached

What is the total pressure of a container in kpa if the partial pressures are 1.25 atm and 66.7 psi?

Answers

Answer:

586 kpa(kilopascal/1000 pascals)

Explanation:

given 1.24 atm(standard atmosphere), and 66.7 psi(pound force per square inch).

To find the total pressure we should use dalton's law of partial pressures which is the sum of the pressures of each individual gas.

then we convert them to pascals and divide by 1000 to get the measurement in kilopascal.

knowing that 1 atmosphere is proportional to around 14.696 psi. We can multiply our given measure of atm by that and sum it by psi like so. 1.24×14.6959 = 18.22298.

Then,

18.22298+ 66.7 = 84.92298

psi.

Since 1 psi is proportional to around 6894.76 pascals. 1 psi will be 68.9476 kilopascal. 84.92298 * 6.89476 = 585.523336 ≈ 586

in an experiment it was found that the total charge on an oil
drop was 5.93 X 10^-18 C How many negative charges does
the drop contain? (#51)

Answers

Answer:

37 negative charges.

Explanation:

We're being asked to determine how many negative charges a drop contains from an oil drop experiment where the total charge was 5.93x10-18 C. The drop contains 37 negative charges.

It was stated and identified that we are to attempt question #51 alone.

From the given information;

The total charge on an oil drop = 5.93 × 10⁻¹⁸ C

According to Oil drop experiment carried out by Robert Milliken in (1910);

In the oil drop laboratory experiment, It was possible for Him to substitute oil for water (because water quickly evaporate). Robert Milikan adjusted the electrical voltage among the two metal plates while the oil drop continues to drop until it stopped. When the drop was stopped, the gravitational downward force on the oil drop was equivalent to the electrical upward force on the charges thereby enabling Robert Millikan to be able to estimate the electrical charge drop.

Robert Milliken identified that the magnitude of a single negative electron charge is:

= 1.6 × 10⁻¹⁹ C

If in an experiment, the total charge =  5.93 × 10⁻¹⁸ C

Then;

The number of negative charges in the oil drop can be calculated as;

[tex]\mathbf{=\dfrac{5.93 \times 10^{-18}}{1.6 \times 10^{-19}}}[/tex]

= 37.063 negative charges

Therefore, we can conclude that the numbers of negative charges contained in the total drop = 37.063.

Shells

The maximum number of electrons that can be accommodated in a shell is based on the principal quantum number (n). It is represented by the formula 2n2, where ‘n’ is the shell number. The shells, values of n, and the total number of electrons that can be accommodated are tabulated below.

Shell and ‘n’ value Max. Electrons in the Electron Configuration

K shell, n=1 2*12 = 2

L shell, n=2 2*22 = 8

M shell, n=3 2*32 = 18

N shell, n=4 2*42 = 32

L shell:  n =2

hence,

Which statement describes an intensive property of matter?

Answers

Answer:

hope it helped you.

Explanation:

The properties of matter that do not depend on the size or quantity of matter in any way are referred to as an intensive property of matter. Temperatures, density, color, melting and boiling point, etc., all are intensive property as they will not change with a change in size or quantity of matter.

An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount. Other intensive properties include color, temperature, density, and solubility.

One differentiating characteristic between vascular and nonvascular plants is the lack of active transport structures in the nonvascular plants. How does the lack of xylem or phloem contribute to the smaller size of the nonvascular plants?

Nonvascular plants are smaller because xylem and phloem help a plant stand up taller.
Nonvascular plants have other transport structures that are microscopic and therefore take up less room.
Nonvascular plants rely upon concentration gradients to move food and water, which only works over small distances.
Nonvascular plants are smaller because they don’t photosynthesize as much as vascular plants and don’t get enough food.

Answers

Answer:

One of the most important characteristics of non-vascular plants is the absence of vascular tissues. Non-vascular plants do not have the vascular tissues known as xylem and phloem. ... As they do not have any vascular tissue, they cannot retain water for long time or transport it to other parts of the plant.

Which property shows that electrons are quantized?

B. Each electron has its own "address."
C. Each electron carries a charge.
D. Electrons have very little mass.

Answers

Answer:

B. Each electron has its own "address."

Explanation:

This is the correct answer.

Good luck with the rest, and have a good day : )

Each electron has its own "address." Therefore, the correct option is option B among all the given options.

What is quantization?

The elementary electric charge of the electron is a negative one, making it a subatomic particle. Due to their lack of components or substructure, electrons, which are part of the lepton particles family's first generation, are typically regarded to be elementary particles. The mass of an electron is roughly 1/1836 that of a proton.

The electron has a half-integer intrinsic rotational momentum that is represented in terms of the decreased Planck constant,, among its quantum mechanical features. The rule of exclusion developed by Pauli states that because electrons are fermions, no two of them may be in the same quantum state. Since they're capable of collide against other particles as well as can be bent like light, electrons, like all primary particles, display both wave and particle characteristics.  Each electron has its own "address."

Therefore, the correct option is option B.

would remain after 10 seconds?
What’s the answr

Answers

Answer:

25 g

Explanation:

The following data were obtained from the question:

Half life (t½) = 5 s

Original amount (N₀) = 100 g

Time (t) = 10 s

Amount remaining (N) =..?

Next, we shall determine the decay constant for the disintegration. This can be obtained as follow:

Half life (t½) = 5 s

Decay constant (K) =.?

K = 0.693 / t½

K = 0.693 / 5

K = 0.1386 s¯¹

Finally, we shall determine the amount of the isotope that remained after 10 s as follow:

Original amount (N₀) = 100 g

Time (t) = 10 s

Decay (K) = 0.1386 s¯¹

Amount remaining (N) =..?

Log (N₀/N) = kt /2.303

Log (100/N) = (0.1386 × 10) / 2.303

Log (100/N) = 1.386 / 2.303

Log (100/N) = 0.6018

Take the anti log of 0.6018

100/N = antilog (0.6018)

100/N = 4

Cross multiply

100 = N × 4

Divide both side by 4

N = 100/4

N = 25 g

Therefore, the amount remaining after 10 s is 25 g
