Recall all the atomic models you described in task 1. think about the results each model would predict for rutherford’s gold foil experiment. which atomic models does rutherford’s experimental evidence support? explain why these models are compatible with the experimental results.

the models in task 1 were dalton's, thomson's, rutherford's, and bohr's.

Answer:

Bohr's

Explanation:

Rutherford's theory laid the foundation upon which Bohr's model is founded. Rutherford established the fact that at the center of the atom, there is a nucleus whose radius is smaller than the radius of the atom. This nucleus is positively charged and most of the mass of the atom is concentrated there. Electrons move round this nucleus in orbits.

The experimental evidences of the Bohr's model shows that Rutherford's model was fundamentally correct. However, Bohr's model introduced the idea of quantization of the energy of electrons in an atom. The model went further to explain the spectra lines of the hydrogen atom.

Explanation:

When you are writing a scholarly paper, you have to conduct a thorough search for source materials online. These sources must be reliable, credible and contain verifiable information. In a project such as writing a paper on the topic 'ocean acidification', the following materials are relevant;

Source 1) 'Functional impacts of ocean acidification in an ecologically critical foundation species,'; Brian Gaylord, Tessa M. Hill, Eric Sanford, Elizabeth A. Lenz, Lisa A. Jacobs, Kirk N. Sato, Ann D. Russell, Annaliese Hettinger; Journal of Experimental Biology 2011 214: 2586-2594; doi: 10.1242/jeb.055939

Source 2) 'Impacts of ocean acidification on marine fauna and ecosystem processes'; Fabry, V. J., Seibel, B. A., Feely, R. A., and Orr, J. C. ; ICES Journal of Marine Science, 65: 414–432; doi: 10.1093/icesjms/fsn048

Answer:

I think that a  pure substance is a form of matter that has a constant composition and properties that are constant throughout the sample. Mixtures are physical combinations of two or more elements and/or compounds.

Explanation:

Answer:

0.067 ton/Litre.

Explanation:

645 Newtons per quart to tons per liter.

We'll begin by converting 645 Newton/quart to gram/quart (g/q). This can be obtained as:

1 N/q = 100 g/q

Therefore,

645 N/q = 645 N/q × 100 g/q / 1 N/q

645 N/q = 64500 g/q

Therefore, 645 Newton/quart is equivalent to 64500 grams per quart.

Next, we shall convert 64500 grams per quart to pounds per quart. This can be obtained as follow:

454 g/q = 1 pound/q

Therefore,

64500 g/q = 64500 g/q × 1 p/q / 454 g/p

64500 gram/quart = 142.07 pound/quart

Therefore, 64500 gram/quart is equivalent to 142.07 pound/quart.

Next, we shall convert 142.07 pound/quart to ton/quart. This can be obtained as follow:

2000 p/q = 1 ton/q

Therefore,

142.07 p/q = 142.07 pq × 1 ton/q / 2000 p/q

142.07 pound/quart = 0.071 ton/quart

Therefore, 142.07 pound/quart is equivalent to 0.071 ton/quart.

Finally, we shall convert 0.071 ton/quart to ton/litre. This can be obtained as follow:

1 ton/q = 1/1.06 ton/L

Therefore,

0.071 ton/q = 0.071 ton/q × 1/1.06 ton/L / 1 ton/q

0.071 ton/quart = 0.067 ton/Litre

Therefore, 0.071 ton/quart is 0.067 ton/Litre.

From the above illustration, 645 Newton/quart is equivalent to 0.067 ton/Litre.

Answer:

B and C are the correct answers.

Answer:

Each atom is left with a complete outer shell. An ionic bond forms between a metal ion with a positive charge and a nonmetal ion with a negative charge.

Answer with Explanation:

A "suspension" is said to be unstable because some of its particles settle at the bottom when it is left for some time. One example of this is the "antibiotic suspension." If you might have noticed, the particles settle at the bottom and this is the reason why it is important to shake the medicine before giving it to patients. Another point to consider is the fact that the suspension has a residue when you try to filter out the particles. This means the solute can be separated from the solvent; thus, it cannot be distributed uniformly. So, this makes it unstable.

Answer:

The study population is the subset of the target population available for study (e.g. schizophrenics in the researcher's town). The study sample is the sample chosen from the study population.

Explanation:

In research terminology the Population can be explain as a comprehensive group of individuals, institutions, objects and so forth with have a common characteristics that are the interest of a researcher. Any value which is identified or measured from the characteristics of entire population can be called as Parameter.

1. Q = 4085.25 J

2. Q = 6288.75 J

Heat can be calculated using the formula:  

Q = mc∆T  

A calorimeter is a device used to measure the specific heat of material

Answer:

Temperature of gas is 3.21×10² K

Explanation:

Given data:

Volume of bulb = 400 cm³        (400/1000 = 0.4L)

Pressure of bulb = 200 KPa      (200/101= 1.974 atm)

Number of moles of gas = 0.03 mol

Temperature of gas = ?

Solution:

Formula:

PV = nRT

R = general gas constant = 0.0821 atm.L/ mol.K

1.974 atm × 0.4 L= 0.03 mol ×  0.0821 atm.L/ mol.K × T

0.7896 atm.L = 0.002463 atm.L/K × T

T = 0.7896 atm.L / 0.002463 atm.L/K

T = 321 K   0r 3.21×10² K

Answer:

C. Decomposition of water

Explanation:

A decomposition reaction occurs when one reactant breaks down into two or more products.This can be represented by the general equation: AB → A + B. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.

The equation for the decomposition of water; 2H2O --> 2H2+O2

Answer:

Option B = 60,600 mg  (correct option)

Explanation:

First of all we will have an idea which numbers are consider as significant.

1 = All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.

2= Leading zeros are not consider as a significant figures. e.g. 0.02 in this number only one significant figure present which is 2.

3= Zero between the non zero digits are consider significant like 105 consist of three significant figures.

4= The zeros at the right side e.g 3400 are also significant. There are four significant figures are present.

In given options, Option A 60.6 mg have 3 significant figures.

Option B have 5 significant figures.

Option C have 4 significant figures.

Option D have 3 significant figures.

Thus option b is correct option which have more significant figures.

Find It Myself, Ask the Community, Get Live Help

Explanation:

The three main options for Microsoft users are Find It Myself, Ask the Community, Get Live Help. The first of which is finding it yourself through the search menu or help guidelines provided by Microsoft in all of their operating systems. Secondly, would be asking the community through search engines such as Google or through Microsoft help forums.
