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.

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.

Therefore, the correct option is b, there were deflected towards a positive electrode.

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.

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.

One way to prove that air is made of matter is to blow up a balloon. Before you add air into the balloon, it is empty and shapeless. When you puff air into it, the balloon expands, so you know it is filled with something—air is taking up space. You'll also notice that a balloon filled with air sinks to the ground.

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.

Answer:

Unstable

Explanation:

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.

Answer:

18.58

Explanation:

From the question given above, the following data were:

Isotope A:

Abundance of A = 54%

Mass of A = 17.984 amu

Isotope B:

Abundance of B = 32%

Mass of B = 18.985 amu

Isotope C:

Abundance of C = 14%

Mass of C = 19.982 amu

Average atomic mass =?

AVERAGE = [(Mass of A × A%)/100)] + [(Mass of B × B%)/100] + [(Mass of C × C%)/100]

AVERAGE = [(17.984 × 54%)/100] + [(18.985 × 32%)/100] + [(19.982 × 14%)/100]

= 9.71136 + 6.0752 + 2.79748

= 18.58

Therefore, the average atomic mass of the isotope is 18.58 amu

Answer:

By adding acid to hydrogencarbonate you create a large concentration of CO2 in solution causing the solution to be highly supersaturated. This keeps the pH down as CO2 is in equilibrium with carbonic acid. During the day long mixing the excess CO2 strips off and as acid leaves the solution the pH increases.

A solution with a pH of 8 will have its pH reduced with the addition of hydrochloric acid.

It is the degree of acidity or alkalinity of solutions.

pH ranges from 0 to 14 with 7 being a neutral pH. Any pH below 7 is acidic while above 7 is basic.

Thus, a pH of 8 is basic and the addition of hydrochloric acid will reduce it towards 7 or even below it.

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."

After various studies and experiments conducted on Pluto's moon, Charon it has been determined that it gets to minus 459.67 degrees Fahrenheit which would be equivalent to minus 273.15 degrees Celsius. This is the coldest temperature that scientists have registered for Charon. This temperature is nearing absolute zero and puts it colder than Pluto itself since Pluto's temperature is believed to get to minus 400 degrees Fahrenheit which is equivalent to minus 240 degrees Celcius.

The scientist witnessed a chemical reaction because a gas was evolved when the two substances were mixed.

A chemical reaction is the same as a chemical change. When a chemical change occurs, atoms recombine to form new substances. Certain occurrences may accompany a chemical reaction such as;

When the scientist mixed purple powder-like substance and a clear liquid together, he noticed that a gas began to bubble out of the mixture. This implies that new substance has been formed so a chemical reaction has taken place.

Among the given options, the one which is not a major function of musculoskeletal system is helping the lungs take in air. All others including, energy, digestion, movement of bones etc. are its function.

The musculoskeletal system in human body is composed of muscles and bones. The bones in our body are wrapped by the muscles. Muscles helps for the smooth movement of bones.

Muscles convert the chemical energy from food into kinetic energy and use  it for the movement of muscles and bones. Muscles contraction needs intake of energy.

The contraction and relaxation of smooth muscles helps for the easy movement of food through the digestive track. Musculoskeletal system also helps for the movement of other organ system. Hence, option b is not the major function of this organ system.
