Explain how the atomic theory was modified from Dalton’s theory to Rutherford’s. Include an explanation of why the theory was modified

Answers

Answer 1

Answer:

Thomson's results showed that atoms contain smaller particles, so Dalton's theory had to be modified. Rutherford's results showed that most of an atom is empty space and that the mass is concentrated in the center of the atom.

Answer:

Virus is living due to reproduction and non-living due to crystal appearance.

Explanation:

Characteristics that viruses display is the ability of reproduction in which they increase in population which is a living character and have DNA or RNA which help them to make exact copies of itself. Virus is parasitic in nature because it causes harm to the living host such as humans, animals and plants. Some characteristics that viruses don't display are that they are not like living cells, have no membrane around them, no organelles such as mitochondria, golgi bodies, endoplasmic reticulum and lysosomes etc. Viruses are present in crystal form outside the cell.

Which statement best describes a compound formed by an ionic bond?

A) negatively charged
B) neutral
C) contains multiple charges
D) positively charged​

Answers

Answer:

B. Neutral

Explanation:

When there is a ionic bond,  one element steals or takes away an electron from the other element.

An example is NaCl

In this compound, Chlorine atom steals an extra electron from Sodium to fill its outer shell. So, this is a Ionic bond. Since, the Sodium compound gives away an atom, it is positively charged. Since, Chlorine steals an atom, it is negatively charged. Opposite charges attract, so they become a compound.

When positive and negative mix, it becomes neutral.

Consider two bulbs seperated by a valce. Both bulbs are amintained at the same temperature. Assume that when the valve between the two bulbs is closed, the gases are sealed in their respective bulbs. When the valve is closed, the following data apply:

Bulb A Bulb B
Gas Ne CO
V 2.50L 2.00L
P 1.09 atm 0.73 atm


Assuming no temperature change, determine the final pressure inside the system after the valve connecting the two bulbs is opened. Ignore the volume of the tube connecting the two bulbs.

Answers

Answer:

The  pressure is [tex]P_f = 0.93 \ atm[/tex]

Explanation:

From the question we are told that

   The  volume of  Ne  is  [tex]V_N = 2.50 \ L[/tex]

    The volume  of  CO is  [tex]V_C = 2.00 \ L[/tex]

    The  pressure of  [tex]Ne[/tex] is  [tex]P_N = 1.09 \ atm[/tex]

      The  pressure of  CO is [tex]P_C = 0.773 \ atm[/tex]

The  number of  moles of  Ne present is evaluated using the ideal gas equation as

      [tex]n_N = \frac{P_N * V_N}{R T}[/tex]

=>   [tex]n_N = \frac{1.09 * 2.50 }{R T} = \frac{2.725}{RT}[/tex]

The  number of  moles of  CO present is evaluated using the ideal gas equation as

      [tex]n_N = \frac{P_C * V_C}{R T}[/tex]

=>   [tex]n_N = \frac{0.73 * 2.00 }{R T} = \frac{1.46}{RT}[/tex]

The  total number of moles of gas present is evaluated as

        [tex]n_T = n_N + n_C[/tex]

        [tex]n_T = \frac{2.725}{RT} + \frac{1.46}{RT}[/tex]

      [tex]n_T = \frac{4.185}{RT}[/tex]

The  total volume of gas present when valve is opened is  mathematically represented as

                [tex]V_T = V_N + V_C[/tex]

    =>        [tex]V_T = 2.50 + 2.00 = 4.50 \ L[/tex]

So

  From the ideal gas equation the final pressure inside the system  is mathematically represented as

         [tex]P_f = \frac{n_T * RT }{ V_T}[/tex]

=>      [tex]P_f = \frac{[\frac{4.185}{RT} ] * RT }{ 4.50}[/tex]

=>       [tex]P_f = 0.93 \ atm[/tex]

     

A student is reading the volume from a standard 50-mL buret identical to what you used in the lab. The bottom of the meniscus is exactly on the 20-mL line. What should she record as the correct volume

Answers

Answer:

20 mL

Explanation:

The student should record 20 mL as the correct volume.

The curved surface of a liquid that is usually observed in a buret is referred to as the meniscus. This meniscus is created as a result of the surface tension of the liquid against the walls of the buret. Hence, in order to avoid errors due to parallax, the bottom of the meniscus should be read and not the top.

Therefore, the correct volume that the student should record is 20 mL.

What happens when two objects when they are brought closer together The mass of both objects decrease The mass of both objects increase The gravitational force between them decreases The gravitational force between them increases

Answers

Answer:

The correct option is

The gravitational force between them increases

Explanation:

According to Newton's law of universal gravitation states that the force of attraction between two bodies is directly proportional to the product of the masses of the bodies and inversely proportional to the square of the distance of their centers from each other.

The formula for universal gravitation is given as follows;

[tex]F_{1} = F_{2} =G \times \dfrac{m_{1} \times m_{2}}{r^{2}}[/tex]

Where;

F₁, and F₂ = The gravitational forces of attraction on each mass

G = The gravitational constant

m₁ = The mass of one body

m₂ = The mass of the body

r = The distance between the centers of the two bodies

Therefore, the gravitational force of attraction on each object is inversely proportional to the as the distance between the centers of the two bodies

When the distance between the centers of the two bodies decreases, the two objects are brought closer together, the gravitational force of attraction between them increases.

Answer:

Gravitational force between two objects of masses m1/m2

Explanation:

is defined by Gm1xm2/r^2, where G is a universal constant, and r is the distance between the masses. This shows you why B is wrong; it would increase. Also, A is not a good choice, as shown. In the case of B, it would increase by say, 2/1 to 4/1 by doubling ones mass. In C's case the bottom would decrease on the fraction alot (square) if they were moved closer, thus the force would be greater.

Explanation:

in other words the  answer is The gravitational force between them increases

A pharmaceutical company is making a large volume of nitrous oxide (NO). They predict they will be able to make a maximum amount of 4860 grams with the materials they have in stock. From the previous 10 volumes they have made, they know that the percent yield of this reaction is fairly low at 47%. How much will the actual yield be? A. 228 grams B. 2284 grams C. 10340 grams D. 486 grams

Answers

Answer:

The answer is "Option B"

Explanation:

From the query, the following knowledge is derived:  

Yield in percentage = 47%  

Performance of theory = 4860 g  

Actual yield Rate =?  

The percentage return is defined simply by the ratio between both the real return as well as the conceptual return multiplied by the 100. It's also represented as numerically:

[tex]Rate = \frac{Existing \ Rate} {Theoretical \ Rate} \times 100[/tex]

Now We can obtain the percent yield as followed using the above formula:  

[tex]\text{Yield in percentage}= \frac{Actual \ yield \ Rate} {Theorical \ Rate} \times 100[/tex]

[tex]47\% = \frac{Actual \ yield \ Rate}{4860}[/tex]

The value of the Actual yield Rate =[tex]47\% \times 4860[/tex]

                                                        [tex]= \frac{47}{100} \times 4860 \\\\ = 2284.2 g[/tex]

The Actual yield Rate= 2284.2 g.

Answers

The correct answer is D. The native species would not have to  compete for necessary resources

Explanation:

Invasive species, which include any living organism that is not native in an ecosystem, contribute to the extinction of native species as they compete for resources such as food, shelter, etc. with native species. For example, the  Asian Carp, which was introduced to lakes in the U.S. consumes plankton, which reduces the amount of plankton available for native fish. In this context, by removing invasive species native species would not have to compete for resources and their chances to extinct will fall.
