Answer:

3d orbital is completely filled.

Explanation:

The mass of \(Al_{2} S_{3}\) produced is 15.616 grams.

The reaction taking place is as follows:

\(2Al+ 3S\) →\(Al_{2} S_{3} (s)\)

Moles of Al = mass/molar mass = 10.0g/27.0g/mol

= 0.370 mol

Moles of S = mass/molar mass = 15.0g/(32.065g/mol)

= 0.468 mol

Al and S reacts in the molar ratio of 2:3.

2 moles of Al reacts with 3 moles of S

0.370 moles of Al will react with S = (3/2)*0.370mol

= 0.555 mol

Similarly, 0.468 moles of S will react with Al = 2/3 *0.468mol

= 0.312 mol

Thus, Al is in excess and S is the limiting reactant (some of Al will be left over ,S will completely react)

So, moles of \(Al_{2} S_{3}\) produced=1/3*0.312 mol of S

= 0.104 mol

Mass of \(Al_{2} S_{3}\) produced = moles*molar mass of \(Al_{2} S_{3}\)

= 0.104mol*150.158g/mol

= 15.616 grams

The difference between the sum of the measures of the interior angles in an octagon and the sum of the measures of the interior angles in a hexagon is 360°.

Interior angle refers to the angle inside a polygon that is formed by two of its adjacent sides. The sum of the measures of the interior angles of a polygon is given by the equation:

180°(n - 2)

where n is the number of sides

An octagon is a polygon that has 8 vertices and 8 sides. The sum of the measures of the interior angles of an octagon is:

180°(8 - 2) = 180°(6) = 1080°

On the other hand, a hexagon is a polygon that has 6 vertices and 6 sides. The sum of the measures of the interior angles of an octagon is:

180°(6 - 2) = 180°(4) = 720°

Subtracting the sum of the interior angles of the two polygons,

1080° - 720° = 360°

To determine the empirical formula, we have to divide each member of moles by the smallest one.

Number of C atoms = 3.237 x 10⁻⁴ / 0.646 x 10⁻⁴

= 5

Number of H atoms = 4.536 x 10⁻⁴ / 0.646 x 10⁻⁴

= 7

Number of N atoms = 0.646 x 10⁻⁴ / 0.646 x 10⁻⁴

= 1

Hence, the empirical formula = C₅H₇N

Now, determine the empirical formula mass:

Mass of C₅H₇N = (5 x C) + (7 x H) + (N)

= (5 x 12 + (7 x 1.008) + (14.007)

= 81.118 g/mol

Divide the molar mass of he compound by the empirical formula mass.

(160 ± 5 gr/mol) / 81.118 g/mol

Answer:

The molarity is 1.26 \(\frac{ moles}{L}\)

Explanation:

Molarity is a unit of concentration that is based on the volume of a solution and represents the number of moles of solutes contained in a liter. The molarity of a solution is calculated by dividing the moles of the solute by the liters of the solution and is expressed in units (moles / liter).

\(Molarity=\frac{number of moles of solute}{Volume}\)

You must calculate the number of moles of CuSO₄. So, being:

the molar mass of CuSO₄ is

CuSO₄=63.54 g/mole + 32 g/mole + 4* 16 g/mole= 159.54 g/mole

Then it is possible to apply the following rule of three: if 159.54 g of CuSO₄ are present in 1 mole, 10 g in how many moles are they?

\(moles=\frac{10 g*1 mole}{159.54 g}\)

moles= 0.063 moles

Then:

Replacing in the definition of molarity:

\(Molarity=\frac{0.063 moles}{0.05 L}\)

Molarity= 1.26 \(\frac{ moles}{L}\)

The molarity is 1.26 \(\frac{ moles}{L}\)

The signs and symptoms of preeclampsia are mainly caused by substances released by the ischemic placenta, which damage the endothelial cells in the mother's body, leading to organ injury.

Preeclampsia is a condition that affects pregnant women and is characterized by high blood pressure and damage to organs, typically the liver and kidneys. The exact cause of preeclampsia is not fully understood, but it is believed to be related to problems with the placenta.

During pregnancy, the placenta supplies oxygen and nutrients to the developing fetus. In the case of preeclampsia, the placenta becomes insufficiently perfused with blood, leading to a state of ischemia (lack of blood flow) and reduced oxygen supply. As a result, the ischemic placenta releases various substances into the mother's bloodstream, such as anti-angiogenic factors, cytokines, and inflammatory mediators.

The concentration (M) of sodium ions in a 0.268 mol/L Na3P solution can be calculated by considering the stoichiometry of the compound. The concentration of sodium ions in the 4.57 L Na3P solution is 0.268 M

In this case, the concentration of Na3P is 0.268 mol/L, and the volume of the solution is given as 4.57 L. Multiplying these values together gives us the number of moles of Na3P in the solution, which is 1.225 mol. Since there are three sodium ions per molecule of Na3P, the number of moles of sodium ions is also 1.225 mol.

To find the concentration of sodium ions, we divide the number of moles of sodium ions by the volume of the solution. Therefore, the concentration of sodium ions in the 4.57 L solution is 1.225 mol / 4.57 L = 0.268 M.

In summary, the concentration of sodium ions in the 4.57 L Na3P solution is 0.268 M, obtained by considering the stoichiometry of Na3P and dividing the number of moles of sodium ions by the volume of the solution.

Differentiating pressure, cryogenic, liquid, and solid containers from a distance can be challenging, as their visual appearance may be similar. However, some general guidelines can help identify the type of container and the likely contents:

Pressure containers are typically cylindrical and have pressure relief valves, gauges, and safety fittings. They are designed to store gases under high pressure and are likely to contain compressed gases such as hydrogen, oxygen, or nitrogen.

Cryogenic containers are heavily insulated and designed to store liquefied gases at very low temperatures. They often have a distinctive shape, with a wide base and a narrow neck. Cryogenic containers may contain liquefied gases such as nitrogen, helium, or argon.

Liquid containers may be similar in appearance to cryogenic containers but do not require heavy insulation. They are designed to store liquids such as chemicals, fuels, or solvents.

Solid containers are typically smaller and may be made of plastic or metal. They are used to store solid hazardous materials such as explosives, flammable solids, or oxidizing agents.

It's important to note that hazardous materials can be stored in any type of container, and that the container itself may not always be a reliable indicator of the contents. Proper labeling, placarding, and handling procedures should always be followed to ensure the safe transport and storage of hazardous materials.

Answer:

The answer is...C

Explanation:

10 meters... because you won't just say your answer is ten or neither can just put meter.

The correct way to write this scientific measurements is 10 meters

The correct answer is: 1.8 moles Fe and 2.7 moles CO2.

In the balanced chemical equation, Fe2O3 + CO → Fe + CO2, the stoichiometric coefficients indicate the mole ratio between the reactants and products. According to the coefficients, 1 mole of Fe2O3 reacts with 3 moles of CO to produce 2 moles of Fe and 3 moles of CO2.

Given that 1.8 moles of Fe2O3 and 2.7 moles of CO are provided, we can determine the number of moles of each product formed. From the mole ratio, 1 mole of Fe2O3 requires 3 moles of CO, so 1.8 moles of Fe2O3 will react with (1.8 moles × 3 moles CO / 1 mole Fe2O3) = 5.4 moles of CO. Therefore, the remaining 2.7 moles of CO will not react fully and will be in excess.

Using the mole ratio, 1 mole of Fe2O3 produces 2 moles of Fe. Since 1.8 moles of Fe2O3 are consumed, the number of moles of Fe produced is (1.8 moles × 2 moles Fe / 1 mole Fe2O3) = 3.6 moles Fe.

Similarly, 1 mole of Fe2O3 produces 3 moles of CO2. Thus, the number of moles of CO2 formed is (1.8 moles × 3 moles CO2 / 1 mole Fe2O3) = 5.4 moles CO2.

Hence, the correct answer is 1.8 moles Fe and 2.7 moles CO2.

The with 25mL of water, what would happen to the boiling point Solution: The main answer is that boiling point will stay the same Boiling point is the temperature at which a liquid vaporizes to a gas at a given pressure. Water has a boiling point of 100 degrees Celsius (at sea level).

The boiling point of water would remain the same even if the volume of water was decreased. If the amount of heat needed to raise the temperature of the water remains constant and only the amount of water is decreased, then the boiling point will remain the same. At any given pressure, the boiling point of a liquid is the temperature at which its vapor pressure is equal to the ambient pressure. The volume of water used in the experiment will have no effect on the boiling point of water. The boiling point is determined by pressure and temperature. If the pressure is the same and the temperature remains the same, the boiling point will remain the same.

HCl, HI, H₂SO₄, LiCl, and KI are all classified as acids. These compounds, HCl, HI, H₂SO₄, LiCl, and KI, all dissociate in water to release hydrogen ions (H⁺), which is the defining characteristic of acids.

Strong electrolytes are substances that completely dissociate into ions when dissolved in water, resulting in a high electrical conductivity. HCl, HI, H₂SO₄, LiCl, and KI all fall under this category. When these compounds dissolve in water, they break apart into their constituent ions, such as H⁺ and Cl⁻ for HCl, H⁺ and I⁻ for HI, H⁺ and SO₄²⁻ for H₂SO₄, Li⁺ and Cl⁻ for LiCl, and K⁺ and I⁻ for KI.

These ions are capable of conducting electricity in the solution, hence qualifying these compounds as strong electrolytes. It's important to note that strong electrolytes undergo complete ionization, meaning that nearly all of the compound dissociates into ions.
