Recall all the models you described in task 1.(Bohr, Rutherford, Thomson, and Dalton) Think about the results each model would predict for Thomson’s experiment. Which atomic models does Thomson’s experimental evidence support? Explain why these models are compatible with the experimental results.
Thomson's experimental data does support the Rutherford model.
What is an atom?The atom consists of matter that may be split without releasing electrical charges.
It's also the smallest unit of matter with chemical element features. As a result, the atom is the fundamental unit of science.
Rutherford was the one who first published the nuclear model of the atom. According to his atomic model, an atom's volume is largely empty,
The center of the atom houses the nucleus, which is made up of protons and neutrons, and its electrons follow certain pathways as they orbit it.
When compared to Rutherford's discoveries, the study of certain other scientists, like Dalton, Neil Bohr, and JJ Thomson, is mostly consistent.
For instance, Dalton's atomic theory assumed that atoms interact to create compounds and are nearly the same size.
Rutherford's theory states that atoms have a finite amount of electrons that may be shared to form compounds.
Rutherford's discoveries, which gave rise to the concept of shells, are also consistent with the Bohr model, which holds that electrons orbit the nucleus in certain shells.
Despite the fact that Rutherford's model was the best atomic model, it nevertheless drew from a number of prior studies and was compatible with their findings.
Hence Thomson's experimental data does support the Rutherford model.

Mass of hydrate + crucible = 47.29 g
Mass of anhydrous salt = 2.7 g
Molar mass of anhydrous salt CuSO4 = 159.5 g
Given,
mass of empty crucible = 42.45 g
mass of hydrate salt= 4.84 g
mass of crucible after first heating = 46.1 g
mass of crucible after second heating= 45.153 g
mass of crucible after third heating= 45.15 g
so, as per the question we need to find...
Mass of hydrate + crucible = ? g
Mass of anhydrous salt = ? g
Molar mass of anhydrous salt CuSO4 = ? g
∴Mass of hydrate + crucible = 42.45 + 4.48 = 47.29 g
The given salt is in hydrate form, to remove water from this molecule we need to perform heating .
So we are taking the substance into the crucible as it is in less quantity.
Here, we performed heating 3 times and note the weight after every heating.
After this, assume that the water is totally evaporated and the remaining salt is in anhydrous form,
∴ Mass of anhydrous salt = 45.15 - 42.45 = 2.7 g
To find the molar mass of anhydrous salt of CuSO4,
atomic weight of Cu = 63.5 g
atomic weight of S = 32 g
atomic weight of O =16 g
∴ molar mass of anhydrous salt of CuSO4 = 63.5 + 32 + (16 ×3)
=159.5 gm

So, in 1 mol there are 6.02x10^23 atoms, regardless of the susbtance, only the weight of the mol changes. Doing a simple rule of 3 we can get many of the answers to your questions.
Explanation:
1mol of Ar → 6.02x10^23 atoms
0.25 mol → X
So now what we do is (0.25mol * 6.02x10^23 atoms)/1 mol = X
That gives us 1.505x10^23 atoms in 0.25 mol of Ar.
For this I'm guessing you mean the stable form of oxygen, O2. The Avogadro constant stays well, constant.
1 mol of O2 → 6.02x10^23 molecules
1.0×10^-4 mol of O2 → X molecules
So you can do (1.0×10^-4 * 6.02x10^23) / 1mol = X
(I feel like this is homework, so i will help you, but not give you all the answer, will be good practice to try yourself) :)

what mass of aluminium is required to produce 500g of aluminium chloride?
2Al + 3Cl₂ --> 2AlCl₃
Answer:
101.18 grams
Explanation:
From the equation you can see that the same number of MOLES will be required as MOLES of aluminum chloride produced.
Mole weight of aluminum chloride = 26.981 + 3 * 35.45 = 133.331 gm
500 gms of this is then 500 / 133.331 = 3.75 moles
So you need 3.75 moles of aluminum
3.75 moles * 26.981 g/mole = 101.18 grams of Al
101.07 grams of aluminum (Al) are required to produce 500 grams of aluminum chloride (AlCl₃) according to the given chemical equation.
Mass is a fundamental physical property of matter that represents the amount of substance contained in an object. It is a measure of the total amount of matter or material in an object, and it is typically measured in units such as grams (g) or kilograms (kg).
Molar mass, also known as molecular mass or formula mass, is the mass of one mole of a chemical substance. It is usually expressed in grams per mole (g/mol). Molar mass is a fundamental concept in chemistry that allows scientists to relate the mass of a substance to the number of moles it contains.
The balanced chemical equation is:
2Al + 3Cl₂ → 2AlCl₃
From the balanced equation, 2 moles of aluminum (Al) react with 3 moles of chlorine gas (Cl₂) to produce 2 moles of aluminum chloride (AlCl₃).
Molar mass of Al = 26.98 g/mol
Molar mass of Cl = 35.45 g/mol
Molar mass of AlCl₃ = 2 × (26.98 g/mol) + 3 × (35.45 g/mol)
= 133.34 g/mol
moles of AlCl₃ = mass / molar mass
moles of AlCl₃ = 500 g / 133.34 g/mol
= 3.749 moles
In the reaction, 2 moles of Al react to produce 2 moles of AlCl₃.
Therefore, moles of Al = moles of AlCl₃
moles of Al = 3.749 moles
Step 4: Calculate the mass of Al required:
mass of Al = moles of Al × molar mass of Al
mass of Al = 3.749 moles × 26.98 g/mol
= 101.07 g

Organic and inorganic compounds
Answer:
'An ion has a non-zero electric charge. A radical has an atom with unfilled electron shells and so is very reactive, but is electrically neutral.'
'Atoms are single neutral particles. Molecules are neutral particles made of two or more atoms bonded together.'
'The primary difference that lies between these organic compounds and inorganic compounds is that organic compounds always have a carbon atom while most of the inorganic compounds do not contain the carbon atom in them.'
Organic and inorganic compounds:
Similarities:::---
1) In both organic and inorganic compound, the elements joining in making compound complete their octet.
2) Organic compound shows isomerism (R/S , E/Z , cis/trans, enantiomers, diastereomers, etc), just as inorganic compound do (Δ/Λ, enantiomers, R/S enantiomers, cis/trans, fac/mer isomers, etc).
3) Organic compound and inorganic compounds can be very active in chemical reactions, e.g. organolithium reagents could be flammable or even pyrophoric (generally stored under 10°C), while inorganic reagents like in this paper are quite rapid...
Differences:::---
1) Organic compound are very long in size so they can make polymer but inorganic compound are not very long but its structure might me complex.
2) The boiling,melting point of organic compound is lass than inorganic compound.
3) Organic compound always contains carbon but inorganic compounds might not.
4) Organic compound
_____________________________
Ion and Radical Atoms:
In some sense they are a bit similar. The main difference is that a neutral radical has no charge imbalance between the protons and electrons, but the cation or anion does.
Ions are written with an explicit charge because of that charge imbalance, but radicals may or may not have an imbalance of charge. Just because a molecule is a radical doesn't mean it's neutral.
For example, if you shoot 2-pentanone with an electron beam for Electron "Impact" Mass Spectroscopy, where you essentially study molecules whose structures break into smaller pieces as a result of interacting with stray electrons to identify the molecules, you get a cationic radical (middle, or far right of the following diagram).
