Explanation:

Lithium (Li) is more reactive than Beryllium (Be). This is because Lithium lacks the valence electron that Beryllium has. Elements with a lower amount of valence electrons are less stable than those with full valence shells, causing it to react more easily. Because Lithium only contains 1 valence electron, it is easily transferred/given up to create bonds and form compounds.

Hope this helps ya! Best of luck <3

Compared to beryllium, lithium (Li) is much more reactive (Be). This is due to Lithium's lack of Beryllium's valence electron.

Reactivity in chemistry is a gauge of the ease with which a substance reacts chemically. The chemical may react independently or in combination with other atoms and compounds, and in either case, energy will typically be released. The most reactive substances and elements have the potential to spontaneously or explosively ignite.

They typically ignite when exposed to oxygen in the atmosphere and water. Reactivity is temperature-dependent. The available energy for just a chemical reaction increases with temperature, often increasing its likelihood. The noble gases are the least reactive elements. Hydrogen is the least active catalyst in this group and doesn't produce any stable compounds. Compared to beryllium, lithium (Li) is much more reactive (Be). This is due to Lithium's lack of Beryllium's valence electron.

Therefore, compared to beryllium, lithium (Li) is much more reactive (Be). This is due to Lithium's lack of Beryllium's valence electron.

The initial volume of the gas was approximately 14.5 liters. The molar volume of a gas expresses the volume occupied by 1 mole of that respective gas under certain temperature and pressure conditions. This answer supports our expectation from Charles law.

To find the initial volume, we can use the Ideal Gas Law formula, which is PV = nRT. Here, P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant (8.314 J/mol·K), and T is the temperature in Kelvin. Step 1, Convert the given pressure from kPa to Pa by multiplying by 1000. So, 60.0 kPa * 1000 = 60000 Pa. Step 2, Plug the values into the Ideal Gas Law formula: 60000 Pa * V = 1.50 mol * 8.314 J/mol·K * 115 K. Step 3, Solve for V: V = 1.50 mol * 8.314 J/mol·K * 115 K / 60000 Pa. Step 4, Calculate the volume: V ≈ 14.5 liters.

So, you started with approximately 14.5 liters of gas. Finally, we can use the fact that the initial number of moles of particles was 1.50, and that only 1.00 moles remained after some gas escaped, to calculate the initial volume of the gas, so the correct number is 14.5 liters.

The concentration of the solution of KMnO4 is 2.19 x 10^-4 M. To determine the concentration of a solution of KMnO4 based on its absorbance, we need to use the Beer-Lambert Law.

This law states that the absorbance of a solution is directly proportional to its concentration and the path length of the light through the solution. The equation is A = εbc, where A is the absorbance, ε is the molar absorptivity (a constant that depends on the substance and the wavelength of light used), b is the path length (in this case, 1 cm), and c is the concentration.

We are given the absorbance (A) of the solution of KMnO4 as 0.526 at a wavelength of 540 nm and a path length (b) of 1 cm. We need to find the concentration (c). We are also given the molar absorptivity (ε) of KMnO4 at 540 nm, which is 2.4 x 10^3 M^-1 cm^-1.

Using the Beer-Lambert Law equation, we can rearrange it to solve for concentration (c). The equation becomes c = A/(εb). Plugging in the values we have, we get c = 0.526/(2.4 x 10^3 x 1) = 2.19 x 10^-4 M.

Therefore, the concentration of the solution of KMnO4 is 2.19 x 10^-4 M.

To determine the concentration of the KMnO4 solution, we need to use the Beer-Lambert Law, which relates the concentration of a solution to its absorbance.

The Beer-Lambert Law is expressed as A = ɛlc, where A is the absorbance, ɛ is the molar absorptivity (in units of L/(mol·cm)), l is the path length (in cm), and c is the concentration (in mol/L).

We are given that the absorbance of the KMnO4 solution is 0.526, the path length is 1 cm, and the wavelength is 540 nm. We need to find the concentration.

To do this, we need to determine the molar absorptivity (ɛ) of KMnO4 at 540 nm. According to literature values, the molar absorptivity of KMnO4 at 540 nm is 2.33 × 10^3 L/(mol·cm).

Now we can plug in the given values into the Beer-Lambert Law and solve for the concentration:

A = ɛlc

0.526 = (2.33 × 10^3 L/(mol·cm)) x (1 cm) x c

c = 0.000226 mol/L

Therefore, the concentration of the KMnO4 solution is 0.000226 mol/L.

Answer: In a 1.48 M iron (III) hydroxide (Fe(OH)3) aqueous solution, the solute is iron (III) hydroxide.

Explanation:

The substance present in small quantity in a solution is called solute.

For example, in a 1.48 M iron (III) hydroxide aqueous solution the solute is iron (III) hydroxide.

The substance present in high quantity in a solution is called solvent.

For example, solution of iron (III) hydroxide is made by dissolving iron (III) hydroxide in water. So, water is the solvent.

Thus, we can conclude that in a 1.48 M iron (III) hydroxide (Fe(OH)3) aqueous solution, the solute is iron (III) hydroxide.

If an atom of 186ta has a mass of 185.958540 amu. mass of1h atom = 1.007825 amu mass of a neutron = 1.008665 amu, the mass defect of 186Ta is 2.04146 amu/atom.

The mass defect is the difference between the mass of an atom and the sum of the masses of its constituent particles. To calculate the mass defect, follow these steps:

Determine the number of protons and neutrons in the nucleus.186Ta is the isotope of tantalum with a mass of 185.958540 amu. There are Z protons and N neutrons in the nucleus. Z is the atomic number.186Ta has an atomic number of 73, indicating that it has 73 protons.  

Therefore, the number of neutrons in 186Ta is N = A - Z = 186 - 73 = 113. The number of protons is 73, and the number of neutrons is 113.

Calculate the total mass of the nucleus by adding up the masses of the protons and neutrons. The mass of 73 protons is 73 x 1.007825 amu = 73.7 amu.

The mass of 113 neutrons is 113 x 1.008665 amu = 114.3 amu.

The total mass of the nucleus is 73.7 + 114.3 = 188.0 amu.

Calculate the mass defect. The mass of 186Ta is 185.958540 amu. The mass defect is equal to the mass of the nucleus minus the mass of the atom.

Therefore,

mass defect = (mass of nucleus) - (mass of the atom)

= 188.0 - 185.958540

= 2.04146 amu.

The mass defect of 186Ta is 2.04146 amu/atom.

Liquification of gas refers to the transformation of a gas into a liquid state. Liquefaction of gas occurs when gases are cooled down to a temperature below their boiling point, or when the pressure on them is raised over their vapour pressure.

Condensation occurs when a gas or vapor cools down, leading to the conversion of its particles into a liquid state. This transition happens as the particles lose energy and come closer together, forming droplets. It is a fundamental process in the water cycle and responsible for the formation of clouds, rain, and other forms of precipitation.

There are many ways in which gas can be liquefied. In this article, we will discuss some of the methods used to liquefy gases: Cooling method Under this method, gases are liquefied by cooling them to temperatures lower than their boiling points. This method is used for gases that have high boiling points. The cooling of gases occurs at a low temperature and high pressure.

This method is commonly used to liquefy carbon dioxide and nitrogen gases. The gases are compressed into a cylinder and then cooled to a temperature below the boiling point of the gas. Once the gas has been cooled, it liquefies, and it can then be stored in the cylinder until it is needed. Compressed liquid gases are commonly used in many industrial applications.

For example, liquid nitrogen is used to freeze food products, and liquid carbon dioxide is used in the production of carbonated drinks. Compression method Under this method, gases are compressed under high pressure to force them to liquefy.

When gases are compressed, the pressure exerted on them increases, causing their boiling points to rise. As the temperature of the gas increases, it reaches a point where it is above its boiling point. At this point, the gas begins to liquefy. This method is commonly used to liquefy hydrogen, helium, and oxygen gases. The gases are compressed into a cylinder, and the pressure is increased to force them to liquefy.

Once the gas has been liquefied, it can be stored in the cylinder until it is needed. Fractional distillation method Under this method, gases are liquefied by subjecting them to fractional distillation. Fractional distillation is a process that involves the separation of the components of a mixture based on their boiling points. This method is commonly used to liquefy natural gas.

In this process, natural gas is first cooled down to a temperature below its boiling point. Once the natural gas has been cooled, it is then passed through a distillation column. In the distillation column, the natural gas is separated into its components based on their boiling points.

The components of the natural gas that have higher boiling points liquefy and are collected at the bottom of the column. The components that have lower boiling points are collected at the top of the column. This method is commonly used in the petrochemical industry to separate different components of crude oil.
