A battery contains two metals that have different tendencies to attract electrons. If one is lithium with an electron affinity of −3.05, and the other is zinc with an electron affinity of −0.76, describe how the electrons will flow. Then, describe how you could make this an even stronger battery.

Answers

Answer 1

This battery could be made stronger when we make lithium the anode and make zinc the cathode.

What is the electron affinity?

We know that the term electron affinity has to do with the fact the a specie is able to attract electrons. Hence, the specie that can be able to attract electrons is said to be have a greater electron affinity.

If we look at the order of the reactivity of the metals, we can see that the lithium has more tendency to exist as a positive ion as such the electron affinity of the lithium atom is very negative and it does not attract electrons.

Answers

Answer:

Gggg

Explanation:

The indication of the cathode rays that has a large charge to mass ratio is there were deflected towards a positive electrode. The correct option is b.

What are cathode rays?

Cathode rays are the rays that move through the negatively charged electrode the cathode charge to the positively charged electrode which is the anode charge in a vacuum tube.

These rays travel through a pipe in a straight line with speed when there is voltage is applied. They are also called electron beams. There is a cathode ray tube, CRT, which is a vacuum tube on which cathode rays travel.

So, the correct option will be for the cathode rays would be deflected towards a positive charge anode.

A gas at 127 celsius and 10.0 L expands to 20.0 L. What is the new
temperature in kelvin? (You must convert to Kelvin before calculating
this problem

Answers

Answer:

800.3 Kelvin

Explanation:

127°C = 400.15 Kelvin   (because 127 + 273.15)

Charles Law:

[tex]\frac{V1}{T1} = \frac{V2}{T2}[/tex]   Thus, [tex]\frac{10.0 L}{400.15 K} = \frac{20.0 L}{T2}[/tex]

Then, work out the math algebraically.  

T2 = 20.0 / (10.0/400.15)

= 20.0 / 0.02499...

= 800.3 Kelvin

This is assuming the pressure remains constant.

Fire ants move in to a new environment with the lizards.what will most likely happen to the lizard population over the next several years

Answers

Answer:

Some lizards in the eastern U.S. have adapted to invasive fire ants -- which can bite, sting, and kill lizards -- reversing geographical trends in behavioral and physical traits used to avoid predators. A new study describing this reversal appears online on November 29, 2018, in the journal Global Change Biology and reveals that new environmental challenges can override the historical influences that originally determined geographical trends in traits.

"Rapid environmental change, be it from changing climate or the introduction of invasive species, is putting a lot of pressure on native species," said Christopher Thawley, graduate student at Penn State at the time of the study and first author of the paper. "Usually when researchers look at how native species might respond to these kinds of threats, they might measure one characteristic of the animal and at one or a few sites. In this study, we looked at three separate characteristics of eastern fence lizards from thirteen sites spanning a thousand miles and found that these lizards are capable of adapting in a concerted way to meet the threat of invasive fire ants, and in a relatively short time frame."

A chemist analyzes two samples. One sample contains 14g of element x and 6.0 g of element y. The second sample contains 28 g of element x and samples are the same substance

Answers

Answer:

Explanation:

Here's the complete question:

A chemist analyzes two samples.One sample contains 14g of element x and 6.0g of element y.The second sample contains 28g of element x and 6.0g of element y. Does it appear that the two samples are the same substance?

The two samples that we are given in the question are different. They are not the same thing because we can deduce that their components ratio are different.

Sample One contains 14g of element x and 6.0g of element y. The ratio of element x to y is 14/6 = 7/3 = 7:3.

Sample Two contains 28g of element x and 6.0g of element y. The ratio of element x to y is 28/6 = 14/3 = 14:3.

Therefore, they have different ratio for their components and are therefore not thesame.

Heavier noble gases are able to form compounds with other elements under specific conditions because their valence ____are farther from the _____

Answers

Answer:

Heavier noble gases are able to form compounds with other elements under specific conditions because their valence electrons are farther from the nucleus.

Explanation:

The name of noble or inert gas is due to the lack of reactivity with other elements. This is due to its electronic configuration, because its outermost shell or valence shell is always complete, without the need to share, give or receive electrons forming bonds. That is, its outer layer is so stable that the element tends not to react with others except in very specific cases.

These exceptions generally involve the heavier noble gases, such as xenon or radon, capable of forming compounds with fluorine and oxygen. This is because the heavier noble gases have more electron shells than the lighter ones. This characteristic causes the outermost electrons to experience a "shielding" effect due to the action of the inner electrons, and they can then be ionized more easily, since the attraction they receive from the positive charges of the nucleus is weaker. That makes the ionization energy low enough to form stable compounds with more electronegative elements, such as fluorine and oxygen.

Heavier noble gases are able to form compounds with other elements under specific conditions because their valence electrons are farther from the nucleus.

cell

Explain why you have them in this order. Be sure
to use a 5 complete thoughts.
:

Answers

Answer:

Atom, cell, dust particle, ant, ping pong ball

Explanation:

Firstly, atoms make up all matter, including each of the items on that list. The only things smaller than atoms are the parts of the atom itself, protons, neutrons and electrons. Because none of those are on that list, atoms have to be the smallest. Next smallest is the cell. Cells are made up of atoms, but they also in part make up dust. You can see a dust particle with the naked eye, but in order to see a cell you must use a microscope. Thus, cells are smaller than dust particles. Next is an ant. Obviously, an ant is bigger than a speck of dust, and is made up of cells and atoms. Lastly all you have is the ping pong ball, which is much larger than the rest of the items. Hope this helps!

All matter, including each thing on the list, is made up of atoms. The protons, neutrons, and electrons that make up an atom are the only particles smaller than atoms.

Thus,  Atoms must be the tiniest object because none of those are included in that list. The cell is the next smallest. Atoms make up cells, but dust also makes up a portion of them.

A dust particle can be seen with the unaided eye, but a microscope is required to see a cell.

Cells are hence smaller than dust particles. An ant comes next. Of course, an ant is composed of cells and atoms and is larger than a particle of dust.

Thus, All matter, including each thing on the list, is made up of atoms. The protons, neutrons, and electrons that make up an atom are the only particles smaller than atoms.
