One mole of magnesium chloride has a mass of 95 g. Then the mass of 4.25 moles of magnesium chloride (MgCl₂) is 403.7 g.

Magnesium chloride is an ionic compound with the chemical formula, MgCl₂. It formed through the donation of two valence electrons from the metal magnesium to the chlorine atoms.

The mass of one mole of a compound is called its molar mass. The number of moles of the compound is then the ratio of its given mass to the molar mass.

Atomic mass of Mg = 24 g/mol

atomic mass of Cl = 35.5 g/mol

mass of 2 Cl = 71 g

Then, molar mass of MgCl₂ = 24 +  71 g = 95 g/mol

One mole of  MgCl₂ is 95 g. Then, mass of 4.25 moles of MgCl₂ is

4.95 × 95 = 403.7 g

Therefore, the mass of 4.95 moles of MgCl₂ is 403.7 g.

Answer:

an element with a large number of valence electrons and a large atomic radius

Explanation:

Electronegativity means a tedency when an atom attracts bonding electrons in a covalent bond situation.

» If an atom has many valency electrons [ empty orbitals in outermost shell ], it has difficulty in attracting electrons hence electronegativity low.

» If an atom is large, its nuclear attraction force of incoming electrons is low hence low electronegativity.

\(.\)

The element that would have the lowest electronegativity is an element with a small number of valence electrons and a large atomic radius.

Both electronegativity and atomic radius are periodic trends. Electronegativity increases across the period while atomic radius decreases across a period.

An element that has a small number of valence electrons and a large atomic radius will most likely be a metal hence it will have the lowest electronegativity.

Real gas behavior corrections to the ideal gas law are based on three important factors:

1. Intermolecular forces: Ideal gas law assumes that there are no intermolecular forces between gas molecules, but in reality, gas molecules do interact with each other. These intermolecular forces become significant at high pressures and low temperatures, causing the gas to deviate from ideal behavior.

2. Molecular size: Ideal gas law assumes that gas molecules have negligible volume, but in reality, gas molecules do occupy space. At high pressures, the volume of the gas molecules becomes significant, leading to deviation from ideal behavior.

3. Pressure and volume area : At high pressures and low temperatures, the gas molecules are more closely packed, and the volume of the gas is less than predicted by the ideal gas law. At low pressures and high temperatures, the gas molecules are far apart, and the volume of the gas is greater than predicted by the ideal gas law.

Therefore, the corrections made to the ideal gas law take into account these factors to give a more accurate representation of the behavior of real gases.

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

In the chemical reaction 4NH₃ + 5O₂ —> 4NO + 6H₂O. The mole O₂ required to react with 16 mole NH₃ is 20 moles

4NH₃ + 5O₂ —> 4NO + 6H₂O

From the balanced equation above,

4 moles of NH₃ required 5 moles of O₂.

With the knowledge provided above, we can determine how many moles of O₂ are needed to react with 16 moles of NH₃.

From the above balanced equation,

5 moles of O₂ were needed for 4 moles of NH₃.

Therefore,

moles of oxygen = 5/4 x 16 = 20 moles

As a result, the reaction requires 20 moles of O₂.

Answer:

See explanation

Explanation:

Substances are composed of atoms. The combination of atoms in a substance determines the properties that the substance exhibits.

For instance, if atoms of metals and nonmetals combine, they give rise to ionic substance which are mostly solid and have high melting and boiling points.

On the other hand, atoms of nonmetals combine with each other to form covalent substances having low melting and boiling points and high vapour pressure sometimes.

Similarly, the kind of molecules present in a substance also determine the nature of the substance. For instance, the high boiling point of water is attributed to the polarity of the O-H bond. This explains why it has a much higher boiling point than CH4 of  comparable molar mass but is a non-polar molecule.

To solve this problem, we need to use the principles of stoichiometry and combustion thermodynamics. The A/F ratio is the air-to-fuel ratio by mass, and it is defined as the mass of air required to completely combust one unit mass of fuel. The dew point temperature is the temperature at which the water vapor in the combustion products begins to condense, and it depends on the composition and temperature of the products.

The A/F ratio can be calculated as follows:

First, we need to write the balanced chemical equation for the combustion of ethane:

C2H6 + 3.5 O2 + (0.2 x 3.5) O2 -> 2 CO2 + 3 H2O + (0.2 x 3.5) N2

Here, the 3.5 O2 represents the stoichiometric amount of oxygen required to completely combust one unit mass of ethane, and the 0.2 x 3.5 O2 represents the excess oxygen supplied (20% excess air). The (0.2 x 3.5) N2 represents the corresponding amount of nitrogen in the excess air.

The molecular weights of the reactants and products are:

C2H6: 2 x 12.01 + 6 x 1.01 = 30.07 g/mol

O2: 2 x 16.00 = 32.00 g/mol

CO2: 1 x 12.01 + 2 x 16.00 = 44.01 g/mol

H2O: 2 x 1.01 + 16.00 = 18.02 g/mol

N2: 2 x 14.01 = 28.02 g/mol

Using these values, we can calculate the mass of air required to combust one unit mass of ethane:

A/F = (mass of O2 + mass of N2) / mass of C2H6

= [(3.5 x 32.00) + (0.2 x 3.5 x 28.02)] / 30.07

= 12.53

Therefore, the A/F ratio is 12.53 by mass.

To determine the dew point temperature of the products, we need to calculate the mole fractions of the water vapor and nitrogen in the products, and then use a psychrometric chart or equations to find the dew point temperature. Alternatively, we can use the following simplified equation:

Tdp = (243.12 x ln(RH/100) + 17.62 x T) / (17.62 - ln(RH/100) - T)

Here, Tdp is the dew point temperature in °C, RH is the relative humidity of the products, and T is the temperature of the products in °C.

Assuming the combustion products are initially at a temperature of 25°C and a relative humidity of 100% (i.e., the products are fully saturated with water vapor), we can calculate the mole fractions of the water vapor and nitrogen as follows:

Mole fraction of H2O = (n H2O) / (n H2O + n N2)

= (3 x 0.2) / [(3 x 0.2) + (3.5 x 0.2)]

= 0.3

Mole fraction of N2 = (n N2) / (n H2O + n N2)

= (3.5 x 0.2) / [(3 x 0.2) + (3.5 x 0.2)]

= 0.35

Using these values

Answer: Cr2(SO4)3 its this

Explanation:

The situation which would have caused the clear yellow solution to remain as is in dibenzalacetone synthesis at the end of 30 minutes can be due to Insufficient reactants, Inappropriate reaction conditions and Inhibition of the reaction.

The starting materials of dibenzalacetone synthesis are all colorless and turn into a clear yellow solution as they are mixed. The situation that would have caused the clear yellow solution to remain as is at the end of 30 minutes is the reaction having gone to completion. The formation of dibenzalacetone involves the aldol condensation of two moles of benzaldehyde with one mole of acetone.

The reaction is carried out in the presence of a base such as NaOH, which removes the acidic alpha-hydrogens of benzaldehyde and acetone to form the enolate ions. These ions are then condensed to form dibenzalacetone. In a successful reaction, the clear yellow solution will eventually become cloudy as dibenzalacetone forms as a solid precipitate. This can occur if not all of the starting materials were properly mixed or if the reaction did not proceed to completion due to factors such as insufficient heating or the presence of impurities.

Insufficient reactants: If there are not enough starting materials present, the reaction may not proceed to completion, and the yellow solution will not change. Inappropriate reaction conditions: Factors such as temperature, solvent, or pH could affect the reaction. If any of these factors are not optimal, the reaction may not proceed efficiently, leading to an unchanged yellow solution.

Inhibition of the reaction: The presence of any impurities or contaminants in the starting materials or the reaction mixture could potentially inhibit the reaction, causing the yellow solution to remain unchanged. To address these situations, ensure that you have the correct amounts of starting materials, follow the recommended reaction conditions, and work with clean and pure chemicals and equipment.

Molecule A should have a higher melting point than Molecule B because it has more opportunities for intermolecular forces to occur due to its larger surface area and ability to participate in Van der Waals forces in addition to hydrogen bonding.

Both molecules have hydroxyl (-OH) groups, which are polar and capable of hydrogen bonding. However, the rest of the structures of the molecules are different. Molecule A has a long carbon chain, which means it has more surface area and more opportunities for Van der Waals forces to occur. Van der Waals forces are weaker than hydrogen bonding, but they can still contribute to the overall strength of the intermolecular forces.

Molecule B, on the other hand, has a cyclic structure, which means it has less surface area than Molecule A. In summary, the melting point of a molecule is dependent on the intermolecular forces between its molecules. In this case, Molecule A has a higher melting point than Molecule B due to its larger surface area and greater potential for intermolecular forces to occur.
