215 grams of AlCl₃ is equal to 1,61 moles of AlCl₃. The relative molecular mass of the compound AlCl₃ is 133.5 grams/mol.

The mole is one of the basic units used to indicate the amount of substance in the international system of units. The equation for calculating moles is mol = mass / relative atomic mass. To find out the mol of AlCl₃ you can use the following steps

Step 1: Calculate the relative molecular mass for the compound AlCl₃.

Mr AlCl₃ = ( Ar Al × ∑Al ) + ( Ar Cl × ∑Cl)

              = ( 27 gam/mol × 1) + ( 35,5 gram/mol × 3)

              = 27 gram/mol + 106,5 gram/mol

             = 133,5 grams/mol

Step 2: Calculate the moles of the compound AlCl₃.

n AlCl₃ = mass AlCl₃ ÷ relative molecular mass AlCl₃

            = 215 grams ÷ 133,5 grams/mol

            = 1,61 mol

Baking soda (sodium bicarbonate) is a kitchen staple that can do wonders for cleaning smelly or clogged clothes, appliances, and even drains. As a natural mineral compound, baking soda can dissolve mineral deposits and organic matter such as grease.

Procedure to unclog a shower drain with baking soda and vinegar:

1. Heating Boiling Water

Heat boiling water in a kettle on the stove or in a large flow-through measuring cup in the microwave.

2. Put boil water and Dish soap into drain:

Pour dish soap down the drain and carefully drain the boiling water. Dishwashing liquid can help clear up greasy blockages.

3. Pour Baking Soda Down the Drain

Pour one cup of baking soda down the drain. To do this, it is difficult to pour water directly into the drain using a measuring cup or funnel if the drain is small.

4. Pour in vinegar

Pour one cup of distilled white vinegar down the drain. Don't be surprised by the sound response that occurs. Baking soda is an alkali, whereas vinegar is a weak acetic acid. When they mix, they react rather dramatically, neutralizing each other. The hiss you hear is often a response to knocking on a blockage in the drain.

5. Rinse with plenty of hot water.

Wait 5 minutes when hissing stops. Use this time to boil two cups of water. Rinse the drain with this extra boiling water. If water is leaking from the drain, run hot tap water to flush the debris down the drain. If it doesn't merge, repeat the previous step.

As per the question given,  

To determine the number of molecules of phosphorus pentachloride present in 8.70 grams of this compound, we need to use the following steps:

Determine the molar mass of PCl5, which is the sum of the atomic masses of one mole of P and five moles of Cl:

M(P) = 30.97 g/mol

M(Cl) = 35.45 g/mol

The ice particles have a lower average kinetic energy. Consequently, ice is distinct from the water vapour that develops as the water starts to boil.

Chemistry defines an object's kinetic energy as the amount of work it produces when in motion. Activities like walking, climbing, tossing, and dropping consume kinetic energy.

Kinetic energy is a type of energy that a moving object or particle has. When an item undergoes work—the transfer of energy—by being subjected to a net force, it accelerates and acquires kinetic energy. A moving object or particle's kinetic energy, which depends on both mass and speed, is one of its properties.

The size and mass of an atom are determined by the number of protons, neutrons, and electrons it contains and can increase or reduce size & mass.

Protons and neutrons are the subatomic particles responsible for most of the mass of an atom. Protons have a mass of approximately 1 atomic mass unit (amu), while neutrons have a slightly larger mass of approximately 1.008 amu. Electrons, on the other hand, have a much smaller mass of approximately 0.0005 amu.

The number of protons and neutrons in an atom determines its atomic mass, which is the sum of the masses of all its protons and neutrons. The number of electrons determines the chemical properties of an atom and how it interacts with other atoms.

One common method for separating and recovering a basic compound from a mixture containing an acidic compound and a neutral compound is through a technique called liquid-liquid extraction

In liquid-liquid extraction, the mixture is dissolved in a suitable solvent, which is then mixed with another immiscible solvent that has different affinities for the different components in the mixture. The two solvents will form separate layers, allowing for the isolation of each component.

To extract the basic compound, an acidic aqueous solution is typically used to protonate the basic compound and convert it into a water-soluble salt. The salt can then be extracted from the organic layer by adding the acidic aqueous solution and shaking the mixture. The acidic aqueous solution will then be separated from the organic layer and the basic compound can be recovered by adding a basic solution to the acidic solution to neutralize the salt and free the basic compound.

If lithium hydroxide reacts with gaseous carbon dioxide to form solid lithium carbonate and liquid water. then 0.915 g of carbon dioxide would react with 1.00 g of lithium hydroxide.

The balanced chemical formula for the reaction of carbon dioxide and lithium hydroxide is:

Li2CO3 + H2O = 2 LiOH + CO2.

According to the equation, which is balanced, two moles of LiOH and one mole of CO2 combine to form one mole of Li2CO3.

We must convert the mass of LiOH to moles in order to determine how much CO2 is needed to react with 1.00 g of LiOH. LiOH has a molar mass of:

Lithium's atomic mass is 6.94 and its atomic masses are 15.9994, 1.0079, and 23.95 g/mol respectively.

Hence, 1.00 g of LiOH equals:

1.00 g / 23.95 g/mol equals 0.0417 moles of LiOH

The balanced equation states that 2 moles of LiOH and 1 mole of CO2. The amount of moles of CO2 needed to react with 0.0417 mol of LiOH is therefore:

0.0208 mol CO2 = 0.0417 mol LiOH x (1 mol CO2 / 2 mol LiOH)

Lastly, we can use the molar mass of CO2 to convert the quantity of moles of CO2 to grammes, which is:

1 atomic mass of C plus 2 atomic masses of O equals 44.01 g/mol.

44.01 g/mol times 0.0208 mol CO2 equals 0.915 g CO2

Hence, 0.915 g of carbon dioxide and 1.00 g of lithium hydroxide would react.

The molality of HCl in the solution is[tex]0.00122 mol/kg[/tex]

Molality is defined as the number of moles of a solute in one kilogram of a solvent. In this case, the solvent is water.

To calculate the molality, we first need to calculate the molarity of the solution. Molarity is defined as the number of moles of a solute in one liter of solution.

To calculate the molarity, we need to know the mass of the solute (HCl) and the volume of the solution. The mass of the solute can be calculated using the density of the solution (1.22 g/ml):

Mass of HCl =[tex]Density * Volume[/tex]

Volume = [tex]\frac{Mass}{Density }[/tex]

Volume =[tex]\frac{(12.0 mol/L) }{ (1.22 g/ml) }= 9.839 L[/tex]

Molarity = [tex]\frac{ (12.0 mol/L) }{(9.839 L) }= 1.22 mol/L[/tex]

Now, we can calculate the molality:

Molality = [tex]\frac{ (1.22 mol/L) }{(1000 g/kg) }= 0.00122 mol/kg[/tex]

Ionic compounds need to reach stability in their charges because they are composed of ions, which are atoms or molecules that have gained or lost electrons. The positive and negative charges within an ionic compound must balance out in order to achieve stability. If the charges are not balanced, the compound will be unstable and will tend to react with other ions or molecules in an attempt to reach a state of stability. This is why ionic compounds form crystal lattices, with each ion arranged in a specific position in the lattice so that the positive and negative charges are evenly balanced.

Water is absorbed in the intestine through the process of osmosis. Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration through a semi-permeable membrane.

In the intestine, the semi-permeable membrane is the cell wall of the intestinal epithelium.

As water moves into the intestine, it dilutes the concentration of solutes such as glucose and electrolytes, creating an osmotic gradient. This gradient drives the movement of water into the bloodstream, where it is distributed throughout the body and helps to maintain fluid balance.

In addition to osmosis, active transport mechanisms, such as sodium-glucose cotransporters, also play a role in absorbing water and electrolytes from the intestine. These transporters actively transport solutes and water across the cell membrane and into the bloodstream, further contributing to the regulation of fluid balance in the body.
