The anhydrous magnesium sulfate required to dry a di-ethyl ether solution after performing extractions involving water is enough such that some powder remains free flowing in solution with swirling without clumping.

Extraction is a process which involves transfer of a solute from one phase to another. A cup of tea or coffee prepared represents a process of extraction.The flavor and odor components are extracted from the dried material into the water.

Anhydrous magnesium sulphate works as a drying agent. Magnesium sulfate (MgSO₄) works by forming complex with H₂O in the solvent. It forms a hydrated MgSO₄ precipitate. This precipitate is then filtered out by gravity, which yields an anhydrous product. Due to the high affinity towards water molecules, MgSO₄ removes any amount of water from the extracts.

Due to the presence of an active hydrogen atom, ethyl alcohol reacts with magnesium metal. Diethyl ether, does not have any replaceable hydrogen atom. So, it does not react with magnesium sulfate, therefore, can be dried by anhydrous magnesium sulfate.

Answer:

The energy is released/harnessed in the form of an electrical current.  

Explanation:

The concept of a fuel cell is to harvest the energy of the H2 + O2 reaction in the form of electrical current, not as light, heat, and sound.  Although energy in the light, heat, and sound provide a higher entertainment value, the electricity produced in a fuel cell proves useful in powering computers, electric cars, phones, televisions, toasters, and other electrical and electronic devices.  The TV, phone, and computer provide substitute entertainment.

The amount of energy released is the same.  It is simply in a different form.  

Iron has the ability to dissolve carbon in solution both when it is in the form of austenite (the elevated temperature phase) and when it is in the form of ferrite at room temperature, but the relative ability differs. When in the form of austenite, the solubility of carbon is higher than when it is in the form of ferrite at room temperature.

This is due to the fact that austenite has a face-centered cubic structure, which allows for a greater number of carbon atoms to be accommodated within the lattice. Ferrite, on the other hand, has a body-centered cubic structure, which has less space for carbon atoms in the lattice.

Austenite can hold up to 2.11% carbon by weight, while ferrite can only hold up to 0.022% carbon by weight. This difference in solubility is why the transformation of austenite to ferrite during the cooling of steel results in the precipitation of iron carbide.

Explanation:

Aii. The percentage abundance of each isotopes are:

Isotopes of an element is defined as the atoms of the element having the same number of protons but different neutron number

The percentage abundance of each isotope can be obtain as illustrated below:

Average atomic mass = [(Mass of 1st × 1st%) / 100] + [(Mass of 2nd × 2nd%) / 100]

10.81 = [(10 × A) / 100] + [(11 × (100 - A) / 100]

10.81 = 0.1A + 11 - 0.11A

Collect like terms

10.81 - 11 = 0.1A - 0.11A

-0.19 = -0.01A

Divide both sides by -0.01

A = -0.19 / -0.01

Abundance of 1st isotope, ¹⁰B = 19%

Abundance of 2nd isotope, ¹¹B = 100 - A

Abundance of 2nd isotope, ¹¹B = 100 - 19

Approximately 17.24 grams of sulfur must be used to produce 13.7 liters of gaseous sulfur dioxide at STP. S8(s)+8Oz(g)->8 So2 (g)

To determine the mass of sulfur required to produce 13.7 liters of gaseous sulfur dioxide at STP, we can use the stoichiometry of the given chemical equation. From the balanced chemical equation, we know that 1 mole of S8 reacts with 8 moles of O2 to produce 8 moles of SO2. We also know that at STP, 1 mole of any gas occupies 22.4 liters of volume. Therefore, we can use the following steps to calculate the mass of sulfur required:

Convert the given volume of SO2 to moles using the ideal gas law:

n = PV/RT = (1 atm x 13.7 L)/(0.08206 L.atm/mol.K x 273 K) = 0.535 mol

Use the stoichiometry of the equation to determine the moles of S8 required:

1 mol S8 : 8 mol SO2

x mol S8 : 0.535 mol SO2

x = 0.067 mol S8

Finally, calculate the mass of S8 required using its molar mass:

mass = n x M = 0.067 mol x 256.5 g/mol = 17.24 g

The molarity of a solution with 952 grams of ammonium carbonate dissolved to make 1750 ml of solution is: 0.54 mol/L.

The molarity of a solution can be calculated by dividing the amount of solute (in this case ammonium carbonate) by the volume of the solution. In this case, 952 grams of ammonium carbonate are dissolved in 1750 mL of solution. Therefore, the molarity of the solution can be calculated as follows:

Molarity = (952 g ammonium carbonate) / (1750 mL solution) = 0.54 mol/L

To calculate the molarity, first, we need to calculate the moles of ammonium carbonate. We can do this using the molar mass of ammonium carbonate, which is 53.49 g/mol. We divide the mass of ammonium carbonate by its molar mass to get the number of moles:

(952 g ammonium carbonate) / (53.49 g/mol) = 17.77 mol

Then, we divide this number by the volume of the solution (in liters):

(17.77 mol) / (1750 mL/1000 mL/L) = 0.54 mol/L

Therefore, the molarity of the solution is 0.54 mol/L.

        As per the periodic table, both Potassium and Lithium belongs to group 1 as their valency is 1 because of the presence of only one electron in the outermost shell of electrons i.e., they lose an electron during a chemical reaction to form a stable compound. Furthermore, both are metallic.

        Magnesium belongs to group 2 and hence its valency is two, which is different from potassium though it is metallic. Similiarly, bromine belongs to group 17 and gains one electron during a reaction in contrast to potassium.

Ligand-gated ion channels allow the following ions to pass through the plasma membrane: Na⁺, K⁺, Ca⁺⁺, and Cl⁻.

Ligand-gated ion channels are a type of transmembrane protein that can be found in the plasma membrane of cells. These channels are activated by the binding of a specific ligand, which leads to the opening of the channel and the movement of ions across the membrane.

In the case of ligand-gated ion channels, the ions that can pass through the channel depend on the specific channel and the ligand that is binding to it. However, in general, these channels can allow for the passage of a variety of different ions, including Na⁺, K⁺, Ca⁺⁺, and Cl⁻.

Na+ and K+ are both cations or positively charged ions, that are important for a variety of cellular functions. Na⁺ is involved in the regulation of the body's fluid balance and the transmission of nerve impulses, while K⁺ plays a role in maintaining the electrical potential across the membrane of cells.

Ca⁺⁺ is another cation that is important for a variety of cellular functions, including muscle contraction and neurotransmitter release.

Cl⁻ is an anion, or negatively charged ion, that is involved in the regulation of the body's fluid balance and the transmission of nerve impulses.

Overall, ligand-gated ion channels can allow for the passage of a variety of different ions, including cations and anions, depending on the specific channel and ligand involved.

To solve this problem, we can use the balanced equation and the concept of moles and molarity.

First, we need to find the moles of SbCl3. We can use the formula: moles = molarity * volume (in liters) moles of SbCl3 = 0.825 M * 0.2 L = 0.165 moles Next, let's write down the balanced equation: SbCl3 + 3HCl → SbCl5 + 3H2

According to the balanced equation, 1 mole of SbCl3 reacts with 3 moles of HCl. So, moles of HCl required = 0.165 moles of SbCl3 * 3 = 0.495 moles Now, we need to find the volume of 4.00 M HCl required.

Using the formula for moles: moles = molarity * volume (in liters) We can rearrange the formula to solve for the volume: volume (in liters) = moles / molarity volume of HCl (in liters) = 0.495 moles / 4.00 M = 0.12375 L Now, convert the volume to milliliters: volume of HCl (in mL) = 0.12375 L * 1000 mL/L = 123.75 mL So, 123.75 mL of 4.00 M HCl were added.

Therefore the answer is  123.75 mL of 4.00 M HCl were added.
