The atomic radius of helium is 28 pm.

What is helium?

Helium is indeed an element in the periodic table with the atomic number 2 and the symbol He. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first element in the periodic table's noble gas group. It has the lowest boiling and melting points of any element. It is the second most plentiful and second lightest element in the visible universe. Its abundance is comparable to that of the Sun and Jupiter due to helium-4's extremely high nuclear binding energy (per nucleon) in comparison to the next three elements after helium. This helium-4 binding energy is also responsible for its existence as a byproduct of both nuclear fusion and radioactive decay. Helium-4 is the most abundant element in the universe.

Answer:

See answer below

Explanation:

In this case, you just need to use any acid you want (Like HCl, or H₂SO₄) to do this exercise.

You are given a sample of what you have to do which is:

Acid + metal ------> Salt + hydrogen

As you can see, an acid like the ones I wrote above, have hydrogen atoms, so you should put the hydrogen there. As for the part of salt, you just need to draw the corresponding salt that is formed when the acid reacts with the metal, and write it's name.

Let's do all three equations for you to a better understanding. For all the given examples, I will use HCl as acid, and i will explain one reaction cause the other two reactions happens the same thing, only with a different metal.

1. 2HCl + Zn ------> ZnCl₂ + H₂

As you can see, we just have a displacement reaction where the metal displaces the position of the hydrogen to form the salt and the hydrogen leaves the molecule as a gaseous molecule. Written in words it would be:

Hydrochloric acid + Zinc ----> Zinc chloride + hydrogen

2. 2HCl + Pb -------> PbCl₂ + H₂

Hydrochloric acid + lead ------> Lead (II) chloride + hydrogen

3. 2HCl + Fe -------> FeCl₂ + H₂

Hydrochloric acid + iron ------> Iron (II) chloride + hydrogen

Answer:

b. Electrons have a mass of 1 amu

Explanation:

Mass of electron is 0.00055amu.

Charge= - 1.6×10^−19

By definition, the statement b. is false: Electrons haven't a mass of 1 amu. Electrons have a mass of 0.0005 amu.

All atoms are made up of subatomic particles: protons and neutrons, which are part of their nucleus, and electrons, which revolve around them.

Protons are positively charged, neutrons are neutrally charged, and electrons are negatively charged. Protons and neutrons have roughly the same mass, about 1.674×10⁻²⁴ g, which represents 1 atomic mass unit or amu. An electron has a mass of 9.11×10⁻²⁸ g, which represents 0.0005  amu.

So, the atomic nucleus is the small central part of the atom, with a positive electrical charge and in which most of the mass of the atom is concentrated.

In a neutral atom, the number of electrons is equal to the number of protons, and since they have a negative electrical charge, they compensate.

Then, the statement b. is false: Electrons haven't a mass of 1 amu. Electrons have a mass of 0.0005 amu.

In order for a titration to be effective, the reaction must produce a precipitate. The correct answer is option B, "reaction must produce a precipitate."

For a titration to be effective, the reaction must be stoichiometric, quantitative, and rapid. A stoichiometric reaction is one in which the amount of reactants is proportional to the amount of products.

A quantitative reaction is one in which all the reactants are consumed, leaving no excess. A rapid reaction is one that occurs quickly and does not take a long time to complete.

However, a reaction producing a precipitate is not necessary for the titration to be effective. Hence option B is correct.

An atom is held together by three forces: the strong nuclear force, the electromagnetic force, and the weak nuclear force.

The strong nuclear force is the strongest of the three forces and is responsible for binding the protons and neutrons together in the nucleus of an atom. The strong nuclear force is a short-range force that acts only over a very small distance, and it is strong enough to overcome the repulsive forces between the protons, which are positively charged particles.

The electromagnetic force is the second strongest of the three forces, and it is responsible for binding the electrons to the nucleus of an atom. The electromagnetic force is a long-range force that acts over a larger distance than the strong nuclear force, and it is caused by the attraction between opposite charges (positive and negative).

The weak nuclear force is the weakest of the three forces, and it is responsible for certain types of radioactive decay, such as beta decay. The weak nuclear force is a short-range force that acts only over a very small distance, and it is much weaker than the strong nuclear force and the electromagnetic force.

Overall, the three forces at work that hold an atom together are the strong nuclear force, the electromagnetic force, and the weak nuclear force. These forces act at different ranges and with different strengths, but they all play a crucial role in maintaining the stability and integrity of an atom.

Yes, the argon atoms exert a greater pressure on the walls of the container because they are more massive.

Argon is a noble gas that has a mass of approximately 40 atomic mass units, which is significantly greater than the mass of lighter gases such as hydrogen and helium.The pressure exerted by a gas in a container is directly proportional to the number of gas molecules present and the average kinetic energy of those molecules.

The mass of gas molecules also has a direct impact on the pressure exerted by a gas.When argon molecules are present in a container, they collide more frequently with the walls of the container than lighter molecules such as hydrogen or helium.

These frequent collisions result in a greater pressure being exerted by the argon on the walls of the container than the lighter gases, given the same conditions of temperature and volume.

Thus, since the argon atoms are more massive, they exert a greater pressure on the walls of the container.

For any salt whose cation has neutral properties (such as Na or K) and whose anion is the conjugate base of a weak acid, the aqueous solution will be basic. Hence this statement is true.

When a salt is placed in water, it breaks down into its individual cation and anion components, which become separated and dispersed within the water solution. The behavior of the resulting aqueous solution depends on the properties of these ions.

In the given scenario, the cation (Na+ or K+) has neutral properties. These cations do not possess any acidic or basic characteristics. Therefore, they do not significantly affect the pH of the solution.

On the other hand, the anion is the conjugate base of a weak acid. A conjugate base is the species that remains after a weak acid loses a proton. Weak acids only partially dissociate in water and produce few H+ ions. Consequently, their conjugate bases have a tendency to accept H+ ions from water, making the solution basic.

Overall, when a salt has a cation with neutral properties and an anion that is the conjugate base of a weak acid, the resulting aqueous solution will be basic. This statement is true.

Answer:

Explanation:

The formula for the limiting reagent is Fe, and the maximum amount of iron(II) oxide that can be produced is 0.135 moles.

To determine the limiting reagent and the maximum amount of iron(II) oxide that can be produced, we need to compare the moles of each reactant and their stoichiometric ratios in the balanced equation.

The balanced equation for the reaction is:

4Fe(s) + 3O₂(g) → 2Fe₂O₃(s)

From the balanced equation, we can see that the stoichiometric ratio between iron and oxygen is 4:3. This means that 4 moles of iron react with 3 moles of oxygen to produce 2 moles of iron(II) oxide.

Moles of iron(II) oxide = min (0.270 moles of Fe, (0.579 moles of O₂) × (2 moles of Fe₂O₃ / 3 moles of O₂))

To determine the limiting reagent, we compare the moles of iron and oxygen and choose the reactant that produces the lesser moles of iron(II) oxide. In this case, we have:

Moles of iron(II) oxide produced from 0.270 moles of Fe = 0.270 moles × (2 moles of Fe₂O₃ / 4 moles of Fe) = 0.135 moles

Moles of iron(II) oxide produced from 0.579 moles of O₂ = 0.579 moles × (2 moles of Fe₂O₃ / 3 moles of O₂) = 0.386 moles

Since 0.135 moles of iron(II) oxide is less than 0.386 moles, the limiting reagent is iron.

Therefore, the formula for the limiting reagent is Fe, and the maximum amount of iron(II) oxide that can be produced is 0.135 moles.

The term "the strong nuclear force must be strong enough to overcome the repulsive force of protons, not electrons" describes the error in her chart. An atom is made up of three particles; electrons, protons, and neutrons. Electrons have a negative charge and protons have a positive charge.

Because protons are in such close proximity, there is a strong repulsive force between them which is why it’s surprising that atomic nuclei can exist. The force that binds protons and neutrons together is known as the strong nuclear force. It has a very short range, which is why it only affects particles that are extremely close together. Despite this, the strong nuclear force is strong enough to overcome the repulsive force of protons, allowing for stable atomic nuclei to exist.

However, the statement "the strong nuclear force must be strong enough to overcome the repulsive force of protons, not electrons" is wrong. Electrons aren't held together by the strong nuclear force because they orbit the nucleus and are attracted to the positively charged protons by the electromagnetic force. Therefore, the strong nuclear force must be strong enough to overcome the repulsive force between protons, not electrons.

The illustration of Thomson's atom represents a neutral atom. In this case, the total amount of positive charge and the total amount of negative charge must be equal. This means that there are equal numbers of protons and electrons in the atom. This is what makes the atom neutral.

A neutral atom is an atom that has no electrical charge. An atom is neutral because it has the same amount of positively charged protons and negatively charged electrons. The nucleus of an atom contains protons, which are positively charged particles. Electrons, which are negatively charged particles, are located in the atom's electron cloud around the nucleus.

Electrons, protons, and neutrons are the three components of atoms. Electrons are negatively charged, protons are positively charged, and neutrons have no charge. Electrons are found outside the nucleus of the atom and are continually moving at high speeds.

Explanation:

Water is a polar molecule due to its bent molecular geometry and the electronegativity difference between oxygen and hydrogen.

The oxygen atom in water is more electronegative than hydrogen, resulting in an uneven distribution of charge within the molecule.Since the majority of hydrocarbon bonds are nonpolar, they do not readily interact with polar substances like water. The nonpolar nature of hydrocarbons leads to a lack of significant electrostatic interactions between the hydrocarbon molecules and water molecules. As a result, hydrocarbons are generally insoluble in water.It is important to note that option c) they exhibit considerable molecular complexity and diversity, and option d) they are less dense than water, are not accurate explanations for the insolubility of hydrocarbons in water.
