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.

The answer is He!

The key difference between Dmitri Mendeleev and Henry Moseley's periodic table arrangements lies in the fundamental basis of their organization: C) Moseley arranged the elements based on atomic numbers while Mendeleev arranged the elements based on atomic masses.

Dmitri Mendeleev (1869): Mendeleev's periodic table was the first successful attempt at organizing the elements. He arranged the elements in order of increasing atomic masses and grouped them based on their chemical properties. Mendeleev's periodic table also left gaps for elements that were yet to be discovered, predicting their properties based on the trends of the known elements.

Henry Moseley (1913): Moseley's contribution to the periodic table was the realization that the atomic number (number of protons in the nucleus of an atom) was a more fundamental property than atomic mass. Moseley proposed that the periodic table should be arranged based on increasing atomic numbers rather than atomic masses. This arrangement resulted in a more accurate and systematic organization of the elements.

Answer:

Option A

Explanation:

To know the correct answer to the question, let us write an equation illustrating the formation of MgBr₂.

This is illustrated below:

1. Magnesium (Mg) is divalent element hence it will lose 2 electrons to form magnesium ion (Mg²⁺) as shown below

Mg —> Mg²⁺ + 2e¯

2. Bromine (Br) is a univalent element. Two bromine atom will receive the two electrons (i.e each atom receives 1 electron) to form the bromide ion (Br¯) as shown below:

2Br + 2e¯ —> 2Br¯

Combine both equation

Mg + 2Br + 2e¯—> Mg²⁺ + 2e¯ + 2Br¯

Cancel out 2e¯

Mg + 2Br —> Mg²⁺ + 2Br¯

Thus we have

Br—Mg—Br

From the illustration made above, we can see that two bromine atom is receiving 1 electron each from the magnesium atom

A bond between a nonmetal and a nonmetal is called a covalent bond. The correct answer is option C.

Covalent bonding occurs when two nonmetal atoms share one or more pairs of electrons in order to achieve a stable electron configuration.

This type of bond is characterized by the sharing of electrons between the atoms, rather than the transfer of electrons as in ionic bonding.

An example of a covalent bond between two nonmetals: The bond between two oxygen atoms in an [tex]\rm O_2[/tex] molecule. In this molecule, the two oxygen atoms share two pairs of electrons to form a stable covalent bond.

Therefore, option C. Covalent bond is a bond between a nonmetal and a nonmetal.

Answer:

Ba(OH)2 is a strong base, so it conducts electricity well

Explanation:

The dissociation of a strong electrolyte is apparent by its reaction arrow, which only points toward products. In contrast, the reaction arrow of weak electrolytes points in both directions. The general form of the strong electrolyte equation is: Strong acids, strong bases, and ionic salts that are not weak acids or bases are strong electrolytes.

X     NH3 is a weak base

X     C12H22011 is neutral (not an acid or a base), therefore it a nonelectrolyte

X     CH3COOH is a weak acid and it also dissociates partially.

The substance which is a strong electrolyte is Ba(OH)₂.

Hence Option (B) is correct answer.

Strong electrolyte can be defined as the substance that completely dissociates in to ions.

Strong electrolyte (aq) → cation⁺ (aq) + anion⁻ (aq)

Now lets check all options one by one

Option (A): NH₃

NH₃ is a weak base. NH₃ does not completely ionize so it is a weak electrolyte.

Hence it is incorrect option.

Option (B): Ba(OH)₂

Ba(OH)₂ is a strong electrolyte because it dissociates completely in water.

Ba(OH)₂ (aq) → Ba⁺² (aq) + 2OH⁻ (aq)

Hence, it is correct option.

Option (C): C₁₂H₂₂O₁₁

C₁₂H₂₂O₁₁ is a non electrolyte that means it does not dissociate into ions.

Hence, it is incorrect option.

Option (D): CH₃COOH

CH₃COOH is a weak electrolyte due to the presence of lowest number of ions it does not dissociate. It's ionization is very less.

Hence, it is incorrect option.

Thus, from the above conclusion we can say that The substance which is a strong electrolyte is Ba(OH)₂.

Hence Option (B) is correct answer.

Option B, P and Cl

They form covalent bond

Answer:

When an atom loses electron(s) it will lose some of its negative charge and so becomes positively charged. A positive ion is formed where an atom has more protons than electrons. In the opposite case when an atom gains electron(s) it becomes negatively charged (more electrons than protons).

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:

c.metal

Explanation: metal is able to carry heat

Answer:

Explained below

Explanation:

The human body has a normal core temperature of around 37°C to 38°C.

Now, if it is heated up to say 39° to 40°C, fatigue will start to set in and the brain begins to tell the muscles to slow down.

If it's now heated to higher temperatures above above 41°C, the body will begin to experience heat exhaustion and therefore will start to shut down.

Due to this process, the body can't even sweat at that stage because blood flow to the skin will stops thereby making the body feel cold and clammy. Thus, chemical processes/reaction in the body will begin to be affected and the cells inside the body will start to deteriorate and thus there is now a huge risk of having multiple organ failure.
