Answer:

The surface tension of water is high due to the dipole nature of water, meaning that the water molecules pull on each other by electrical charge. Soap and detergents interrupt this layer, reducing the surface tension.

A visual, though not scientifically accurate, would be a set of magnetic marbles that form a sheet. If you randomly stick in glass marbles the overall strength decreases since they are not all pulling together in order.

There are some substances, called super wetters, generally silicone surfactants that give a truly amazing drop in surface tension, where a small puddle of water can spread to many times it’s own size. These types of surfactants are used in laundry detergent and french fry oil to prevent foaming and in polymers to promote flow.

Explanation:

Answer:

When a neutral atom loses one or more electrons, the total number of electrons decreases while the number of protons in the nucleus remains the same.

The result is that the atom becomes a cation —an ion with a net positive charge.

The opposite process can also occur. When a neutral atom gains one or more electrons, the total number of electrons increases while the number of protons in the nucleus remains the same.

The result is that the atom becomes an anion —an ion with a net negative charge.

The statement "The orbit of a comet is one of nature's cycles" is True because The orbit of a comet is a natural cycle that follows the laws of physics and determines its path around the Sun.

Comets have highly elliptical orbits that can take them far away from the Sun and then back again, following a predictable cycle that can span many years or even centuries. This cycle of orbit is a natural phenomenon that occurs due to the gravitational forces of the Sun and other celestial bodies.

Comets are celestial bodies that follow an elliptical orbit around the Sun. Their orbit is determined by the gravitational forces acting on them from the Sun and other celestial bodies, such as planets and moons. The path of a comet is predictable and follows the laws of physics, which govern the motion of all celestial bodies.

As the comet approaches the Sun, it heats up and releases gas and dust, creating a glowing tail that can be seen from Earth. This tail always points away from the Sun, due to the solar wind blowing the gas and dust particles away from the comet.

The orbit of a comet is a natural cycle that repeats itself over time. Depending on the shape and size of the comet's orbit, its cycle can span many years or even centuries. For example, Halley's Comet, one of the most famous comets, has an orbit that takes it around the Sun every 76 years. This means that it follows a predictable cycle, and astronomers can calculate when it will be visible from Earth again.

In summary, the orbit of a comet is a natural cycle that is determined by the laws of physics and the gravitational forces of celestial bodies. This cycle determines the path of the comet around the Sun and can span many years or even centuries.

Spectrographs are useful to astronomers as they  help in studying the composition of a star as each component absorbs light at specific wavelengths.

It is defined as a graph which depicts the spectral information about the component. Spectrographs consisting of lines  are  called atomic spectra as the lines represent wavelengths which are radiated from atoms when electrons jump or make a transition from one energy level to another.

Band spectra is given to a group of lines spectrum which are so close that they appear like a band . They are produced by molecules when they radiate their vibrational or rotational energies.

Amount of light which is absorbed is unique for each element and hence astronomers can measure  the position of lines  to determine which elements are present in the target.

Answer:

Answer:Electrical Conductivity,soluble

Explanation:

Salt is a non-magnetic solid and is soluble in water. Sand is a non-magnetic solid and is insoluble in water.

Electrical Conductivity: Salt is an electrolyte and conducts electricity when dissolved in water or in a molten state. This is because salt dissociates into ions (Na+ and Cl-) that can carry electric current. In contrast, sand is a covalent compound and does not conduct electricity, as it does not dissociate into ions in the same way as salt. Sand is considered an insulator in terms of electrical conductivity.

Explanation: The rate law for a chemical reaction is an equation that relates the rate of the reaction to the concentrations of the reactants. To determine the rate law for a reaction, experiments are typically conducted with different initial concentrations of the reactants and the initial rate of the reaction is measured.

From the data provided, it appears that the reaction is of the form X + Y → C. And the concentration of X and Y are varied in three trials and the corresponding Initial rate is measured.

In the first trial, [X] = 0.01 M and [Y] = 0.015 M, and the initial rate of the reaction is 7.83x10-5 M/s.

In the second trial, [X] = 0.01 M and [Y] = 0.03 M, and the initial rate of the reaction is 3.13x104 M/s.

In the third trial, [X] = 0.02 M and [Y] = 0.015 M, and the initial rate of the reaction is 1.57x10 M/s.

Given the data, the rate law for this reaction is OR = KX²M. This is because when the concentration of X is doubled, the rate of the reaction is quadrupled, which is consistent with a rate law of the form OR = k[X]^2.

Explanation:

The number of moles of \(MnO_2\) required is  3.345 moles.

In the given reaction, the balanced equation shows that for every 4 moles of \(MnO_2\), 4 moles of \(KMnO_4\) are produced. Therefore, we can use the stoichiometry of the reaction to calculate the moles of \(MnO_2\) and the moles of \(KMnO_4\)

Given:

Mass of \(MnO_2\) = 291 g

Molar mass of\(MnO_2\) = 87 g/mol

To find the moles of \(MnO_2\), we use the formula:

Moles = Mass / Molar mass

Moles of \(MnO_2\) = 291 g / 87 g/mol = 3.345 mol

Now, since the stoichiometry of the reaction tells us that the ratio of \(MnO_2\)to \(KMnO_4\) is 4:4, we can conclude that 3.345 moles of \(MnO_2\)will produce an equal number of moles of \(KMnO_4\)

Therefore, the moles of \(KMnO_4\) produced will also be 3.345 mol.

However, the question asks for the moles of NaOH, which is not directly related to the given reaction. We cannot determine the moles of NaOH based on the information provided.

To find the moles of NaOH, we would need additional information or another relevant equation that includes NaOH.

There are vacant orbitals on the phosphorus atom that allows it to expand its octet.

There is a concept that we would need to consider as we are answering the question that we here and that is the idea of the octet rule. The octet rule states that it is only about eight electrons that can be found on the outermost shell of an atom and as such all of the compounds can be formed in obedience to this rule.

Now we should know that there are no vacant d orbitals that are present on the nitrogen atom and this stems from the fact that it does not have a 3d level as such there are no orbitals that can be able to help the Nitrogen atom so as to be able to expand its octet. This is the reason why its pentafluoride can be easily formed.

What is an heterogeneous system?

By definition is a chemical system that contains various distinct and mechanically separable phases.

If we take a quick look at the reactions that we were given we will see that the is only one where we have more that one phase.

c) H2(g) + O2(g) <=====> H2O(l)

In that case we have in equilibrium two gases with one liquid, in the other ones we only have gases.

So the heterogeneous system is C.

Given to us is the Reaction of Aluminium metal with Chlorine gas . That is ,

\(\boxed{\red{\bf \underset{\blue{Aluminium}}{2Al(s)}+\underset{\blue{Chlorine}}{3Cl_2(g)}\longrightarrow \underset{\blue{Aluminium\: chloride}}{2AlCl_3}}}\)

Now Mass of 1 mole aluminium = 27g . So mass of 2 moles of it would be 27×2 g = 54g .

Also , Mass of 1 mole of chlorine gas = 35.5 g . So mass of 2 Atoms will be 71g . And mass of 3 moles of atom will be 71 × 3g = 213g .

Now , use unitary method ;

213 g of Chlorine reacts with 54g of Aluminium.

1 g of Chlorine will react with \(\sf\dfrac{54g}{213g}\) of Aluminium.

Hence 52.9 g of Chlorine will react with \(\sf \dfrac{54}{213}\times52.9g\)=\(\bf 13.41g\) of Aluminium.

Hello, this is Bing. I can help you with your question. Based on the information I found on the web, **H2** can be broken down into its two atoms of hydrogen (H) by supplying enough energy to overcome the bond that holds them together⁴. This process is called **dissociation** and requires an energy equal to or greater than the **dissociation energy** of H2, which is about 436 kJ/mol⁴.

One way to break down H2 is by using **electricity** to split water (H2O) into hydrogen (H2) and oxygen (O2) through a process called **electrolysis**¹. In this process, water is decomposed into its elements by passing an electric current through it. The electric current is provided by a battery or another source of electricity and the water needs to have an **electrolyte**, such as salt or acid, added to it to make it conductive¹. Two electrodes, usually made of metal or other conductive material, are inserted into the water and connected to the battery. The electrode connected to the positive terminal of the battery is called the **anode** and the one connected to the negative terminal is called the **cathode**¹. When the electric current flows through the water, hydrogen gas bubbles form at the cathode and oxygen gas bubbles form at the anode¹. The overall chemical reaction for electrolysis of water is:

2 H2O → 2 H2 + O2

Another way to break down H2 is by using **heat** to cause a reaction between hydrogen and oxygen that produces water and releases a large amount of energy. This reaction is called **combustion** or **oxidation** and can be ignited by a spark or a flame³. The reaction is very fast and explosive and can be dangerous if not controlled. The overall chemical reaction for combustion of hydrogen is:

2 H2 + O2 → 2 H2O

I hope this helps you understand how H2 can be broken down and what methods are used to do so.
