The grams of 0.119 g of magnesium nitride was used up in the reaction.

To solve this problem, we need to use the ideal gas law PV = nRT where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.

First, we need to convert the volume of ammonia from liters to m³ is 13.0 L = 0.0130 m³. Next, we can rearrange the ideal gas law to solve for the number of moles n = PV/RT where R = 0.08206 L·atm/(mol·K) is the gas constant.

Plugging in the values, we get

n = (1.00 atm)(0.0130 m³)/(0.08206 L·atm/(mol·K))(23°C + 273.15)

= 0.00708 mol

Now, we need to use the balanced chemical equation to relate the number of moles of ammonia to the number of moles of magnesium nitride.

From the equation, we can see that 6 moles of ammonia react with 1 mole of magnesium nitride. Therefore, the number of moles of magnesium nitride used up in the reaction is mass

= 0.00118 mol × 100.95 g/mol

= 0.119 g

Answer:

0.142

Explanation:

Answer:

0.142 moles.

You would have to convert the algorithm to a broken down version of the compound.

NH4NO3(aq] → NH+4(aq] + NO−3(aq]

The ammonium is removed for this case, concentration gets broken down to zero.

So here, if 1 liter is equal to 10 x 10 x 10 milliliters...

use the formula of n and c to help you figure out the moles.

C is equal to N divided by V, so in that case...

N equals C times V.

C times V is 0.425, or 17 over 40 in simplest form.

From there, multiply 17 over 40 by the current moles, cross out the liters, and multiply by 335, then, 10 to the power of -3. You have to flip it to negative, because it will cancel out either way. Change the equation by the liters, and you have 0.125

Hence, your correct answer is 0.125

The observed difference in basicity between para-nitroaniline and meta-nitroaniline can be attributed to the position of the nitro group on the aromatic ring. In para-nitroaniline, the nitro group is located in the para position, which causes a greater electron-withdrawing effect on the amino group.

This results in a weaker basicity for para-nitroaniline compared to meta-nitroaniline.As for the basicity of ortho-nitroaniline, it is expected to be closer in value to meta-nitroaniline. This is because the nitro group in ortho-nitroaniline is located in the ortho position, which allows for a resonance stabilization of the amino group. This resonance effect can partially counteract the electron-withdrawing effect of the nitro group, resulting in a stronger basicity for ortho-nitroaniline compared to para-nitroaniline but weaker than meta-nitroaniline.

Using the calculated molarity of the unknown acid, you can use the Rice table to determine the initial pH of the solution.


The rice table is a tool that is used to determine the unknown variables when calculating equilibrium concentrations. When titrating an unknown acid, the molarity of the solution is determined by using stoichiometric ratios. Once the molarity of the unknown acid is known, the Rice table can be used to determine the initial pH of the solution.

This is achieved by setting up a table that shows the initial concentration of each species, the change in concentration, and the equilibrium concentration. By using the equilibrium concentrations, it is possible to determine the equilibrium constant and calculate the pH of the solution.

In conclusion, if the initial pH determined using the Rice table matches the actual pH of the titration curve, it confirms that the calculation of the molarity was correct. If the pH values do not match, it is an indication of an error in the calculations, and a recalculation is necessary.

Explanation:

In a regular hexagon with a side length of 6m, the perimeter (P) can be calculated by multiplying the side length by 6, resulting in P = 36m. The area (A) of the hexagon can be found by using the formula A = (3√3/2) * s^2, where s is the side length, giving A ≈ 93.53 square meters.

A regular hexagon is a polygon with six equal sides and six equal angles. Given that one side of the regular hexagon is 6m, we can determine the perimeter and area of the polygon.

To find the perimeter (P) of the regular hexagon, we multiply the length of one side by the number of sides. Since a hexagon has six sides, the perimeter can be calculated as P = 6 * 6m = 36m. Therefore, the perimeter of the regular hexagon is 36m.

To calculate the area (A) of the regular hexagon, we use the formula for the area of a regular polygon. For a regular hexagon, the formula is A = (3√3/2) * s^2, where s is the length of one side. Substituting the given side length of 6m into the formula, we have A = (3√3/2) * (6m)^2 ≈ 93.53 square meters. Therefore, the area of the regular hexagon is approximately 93.53 square meters.

It's important to note that the formulas provided are specifically for regular hexagons, where all sides and angles are equal. If the hexagon is irregular, with sides of varying lengths, the perimeter and area calculations would be different.

The percentage yield of magnesium chloride is 84.16%.

To calculate the percentage yield of magnesium chloride, you would divide the amount of magnesium chloride produced by the theoretical amount that could have been produced and multiply by 100.

First, we will calculate the theoretical yield of magnesium chloride. The balanced equation for the reaction is:

Mg + 2HCl → H2 + MgCl2

So for every 1 mole of Mg, we get 1 mole of MgCl2

To convert mass to moles we use the molar mass of each substance:

Mg = 24.3 g/mol

MgCl2 = 95.2 g/mol

So 100g of Mg is equal to (100 / 24.3) = 4.1 moles of Mg

and the theoretical yield of MgCl2 is 4.1 moles * 95.2g/mol = 391.32 g.

Now we can calculate the percentage yield by dividing the actual yield (330 g) by the theoretical yield (391.32 g) and multiplying by 100:

(330 / 391.32) * 100 = 84.16%.

So the percentage yield of magnesium chloride is 84.16%.

This means that 84.16% of the theoretical yield of magnesium chloride was actually produced in the reaction.

Based on Lewis structures, the ordering of N-O bond lengths is NO+ < NO2- < NO3-.

In Lewis structures, the number of electron pairs around the central atom can affect the bond lengths. The more electron pairs there are, the greater the repulsion between them, which can lead to longer bond lengths.

In NO+, there are two electron pairs around the central nitrogen atom, resulting in a linear structure. The N-O bond length in NO+ is shorter compared to the other two molecules.

In NO2-, there are three electron pairs around the central nitrogen atom, resulting in a bent structure. The presence of an additional lone pair increases the electron-electron repulsion, leading to longer N-O bond lengths compared to NO+.

In NO3-, there are four electron pairs around the central nitrogen atom, resulting in a trigonal planar structure. The presence of two additional lone pairs further increases the repulsion, resulting in the longest N-O bond lengths among the three molecules.

Explanation:

The physical properties of aldehydes and ketones are governed by the presence of a carbonyl functional group. This functional group contains a carbon atom double-bonded to an oxygen atom, which imparts unique chemical and physical properties to aldehydes and ketones.

The polarity of the carbonyl group makes aldehydes and ketones highly reactive with nucleophiles, and it also affects their boiling points and solubility. The dipole-dipole interaction between the carbonyl group and neighboring molecules affects the boiling point of aldehydes and ketones, which increases as the size of the molecule increases. In general, aldehydes have lower boiling points than ketones because they have one fewer carbon atom, making them less polar and less likely to form strong intermolecular forces. Additionally, the presence of the carbonyl group increases the acidity of aldehydes and ketones, making them weak acids. Overall, the unique physical properties of aldehydes and ketones can be attributed to the presence of the carbonyl functional group.

The specific heat of the metal is approximately equal to 3.77 J/g°C.

To calculate the specific heat of the metal, we can use the equation:

q = m * c * ΔT

where:

q is the heat transferred,

m is the mass of the substance (in this case, water),

c is the specific heat capacity of the substance (in this case, water),

ΔT is the change in temperature.

Given the data:

Mass of the metal (m₁) = 50.0 g

Mass of water (m₂) = 100 g

Temperature change of water (ΔT) = 23.5°C

Assuming there is no heat loss to the surroundings, the heat gained by the water is equal to the heat lost by the metal. Therefore, we can write:

m₁ * c₁ * ΔT = m₂ * c₂ * ΔT

Rearranging the equation to solve for the specific heat of the metal (c₁), we have:

c₁ = (m₂ * c₂ * ΔT) / (m₁ * ΔT)

Substituting the given values, we get:

c₁ = (100 g * 4.18 J/g°C * 23.5°C) / (50.0 g * 23.5°C)

Evaluating the expression, the metal's specific heat is about equal to3.77 J/g°C.
