The number of moles of NaOH added.
Please show steps.
Thank you in advance!

Answers

The number of moles of NaOH added is 0.00225 mol.

To calculate the number of moles of NaOH added, we can use the stoichiometry of the reaction between benzoic acid (C6H5COOH) and NaOH. According to the balanced equation, 1 mole of benzoic acid reacts with 1 mole of NaOH. Given that the concentration of NaOH is 0.150 M and 15.0 mL of NaOH solution is added, we can first convert the volume to liters by dividing it by 1000:
Volume of NaOH = 15.0 mL / 1000 mL/L = 0.015 L
Next, we can calculate the number of moles of NaOH using the formula:
moles of NaOH = concentration × volume
moles of NaOH = 0.150 M × 0.015 L = 0.00225 mol
Therefore, the number of moles of NaOH added is 0.00225 mol.

what one test (not using the semicarbazoneor 2,4-dnp derivatives) could be used to differentiate between thefollowing pairs? describe what would you observe? a) 2-pentanone and 3-pentanone b) pentanol and 3-pentanone c) 1-propanol and 2-propano

Answers

To differentiate between the given pairs of compounds, we can use the iodoform test. This test involves treating the compounds with iodine and sodium hydroxide solution.

The observation of a yellow precipitate indicates the presence of a methyl ketone (2-pentanone), while the absence of a precipitate suggests the presence of an ethyl ketone (3-pentanone). In the case of pentanol and 3-pentanone, the iodoform test cannot differentiate between them as both compounds lack a methyl ketone group.

Lastly, in the differentiation between 1-propanol and 2-propanol, the iodoform test is not applicable since both compounds lack a methyl ketone group.

2-Pentanone and 3-Pentanone differentiation:

Perform the iodoform test by adding iodine solution to a test tube.

Add sodium hydroxide solution (NaOH) dropwise to the test tube.

If a yellow precipitate forms, it indicates the presence of a methyl ketone (2-pentanone).

If no precipitate forms, it suggests the presence of an ethyl ketone (3-pentanone).

Pentanol and 3-Pentanone differentiation:

Conduct the iodoform test by adding iodine solution to a test tube.

Add sodium hydroxide solution (NaOH) dropwise to the test tube.

Since both compounds lack a methyl ketone group, there will be no formation of a yellow precipitate. Therefore, the iodoform test cannot differentiate between pentanol and 3-pentanone.

1-Propanol and 2-Propanol differentiation:

The iodoform test is not applicable here since both compounds lack a methyl ketone group. Therefore, the test cannot be used to differentiate between 1-propanol and 2-propanol.

A 10,0-L cylinder of gas is stored at room temperature (20.0°C) and a pressure of 1800 psi. If the gas is
transferred to a 6.0-L cylinder, at what temperature in CELCIUS would it have to be stored in order for the
pressure to remain at 1800 psí? Reminder, convert your temperature to Kelvin before you begin the problem.
(Please put units)

Answers

Considering the Charles' law, the gas would have a temperature of -109.2 C.

Charles' law

Finally, Charles' law establishes the relationship between the volume and temperature of a gas sample at constant pressure. This law says that the volume is directly proportional to the temperature of the gas. That is, if the temperature increases, the volume of the gas increases, while if the temperature of the gas decreases, the volume decreases.

Charles' law is expressed mathematically as:

\(\frac{V}{T} =k\)

If you want to study two different states, an initial state 1 and a final state 2, the following is true:

\(\frac{V1}{T1} =\frac{V2}{T2}\)

Temperature of the gas in this case

In this case, you know:

P1= 1800 psiV1= 10 LT1= 20 C= 293 K (being 0 C= 273 K)P2= 1800 psiV2= 6 LT2= ?

You can see that the pressure remains constant, so you can apply Charles's law.

Replacing in the Charles's law:

\(\frac{10 L}{293 K} =\frac{6 L}{T2}\)

Solving:

\(\frac{10 L}{293 K} T2=6 L\)

\(T2=\frac{6 L}{\frac{10 L}{293 K} }\)

T2=163.8 K= -109.2 C

The gas would have a temperature of -109.2 C.

Ethylene glycol (C2H6O2) is used as an antifreeze in cars. If 400 g of ethylene glycol is added to 4.00 kg of water, what is the molality? Calculate how much the freezing point of water will be lowered. The freezing-point depression constant for water is Kf = –1.86°C/m.

Answers

Answer:

The freezing point of water will be lowered 3°C

Explanation:

Remember that molality is generally the standard for calculating the concentration, between molarity and molality. In this question we have to apply molality, given the units as moles and kilograms.

We can start by receiving the molality of this solution through the following formula...

\(\mathrm{m}=\mathrm{(mass}\mathrm{/molar\:mass)} * (1000/\mathrm{mass\:of\:solvent)},\)

\(\mathrm{m} =\mathrm{(400.0 g / 62.07 g/mol) * (1000 / 4000.0 g)},\)

\(\mathrm{m} = (400/62.07) * (1000 / 4000) = \left(\frac{400}{62.07}\right)\left(\frac{1000}{4000}\right) = \frac{1000}{620.7} = 1.61108\dots\mathrm{m}\)

Now we can determine how much the freezing point of water will be lowered, given that the freezing-point depression constant for water is Kf= –1.86°C/m. Remember that " Kf " is the final temperature, so to determine how much the temperature of the water will decrease, we can note the change in temperature...

\(\mathrm{change\:in\:temperature} = ( - 1.86\mathrm{C/m})(1.61\mathrm{m}) = - 1.86 * 1.61 = -2.9946\)

\(-2.9946 = \mathrm{About\:-3C}\)

Hence the freezing point of water will be lowered 3°C.

What mass of iron should be produced if 11. 0g of aluminum react with 30. 0g of iron (III) oxide?

Answers

The mass of iron should be produced if 11. 0g of aluminum reacts with 30. 0g of iron (III) oxide is 10.50 g.

To determine the mass of iron produced, we need to use stoichiometry and the balanced chemical equation for the reaction between aluminum and iron(III) oxide.

The balanced chemical equation is:

2 Al + \(Fe_{2} O_{3}\) →  + 2 Fe

From the equation, we can see that 2 moles of aluminum react with 1 mole of iron(III) oxide to produce 1 mole of iron.

First, we need to determine the limiting reactant by comparing the number of moles of aluminum and iron(III) oxide.

Moles of aluminum = mass of aluminum / molar mass of aluminum

= 11.0 g / 26.98 g/mol (molar mass of aluminum)

= 0.407 mol

Moles of iron(III) oxide = mass of iron(III) oxide / molar mass of iron(III) oxide

= 30.0 g / 159.69 g/mol (molar mass of iron(III) oxide)

= 0.188 mol

Since the stoichiometric ratio of aluminum to iron(III) oxide is 2:1, we can see that 0.188 mol of iron(III) oxide requires 0.376 mol of aluminum. However, we have only 0.407 mol of aluminum, which is in excess.

Therefore, the limiting reactant is iron(III) oxide. The amount of iron produced is determined by the moles of iron(III) oxide used. Moles of iron = 0.188 mol (same as moles of iron(III) oxide)

Now we can calculate the mass of iron produced using its molar mass (55.85 g/mol):

Mass of iron = Moles of iron × Molar mass of iron

= 0.188 mol × 55.85 g/mol

= 10.50 g

Therefore, the mass of iron produced is approximately 10.50 grams.

What is the difference between sigma and pi bonds in valence bond theory? what orbitals are involved in making these bonds?.

Answers

The overlapping of atomic orbitals distinguishes sigma and pi covalent bonds. When atomic orbitals overlap, covalent bonds form.

The way atomic orbitals overlap affects bond properties such as bond length, bond angle, and bond enthalpy. This overlap occurs in two ways, resulting in two types of covalent bonds: sigma bonds and pi bonds.

This type of covalent bond is formed by head-on positive (same phase) overlap of atomic orbitals along the internuclear axis. Sigma bonds are the strongest covalent connections due to the direct overlapping of the orbitals involved. The electrons in a bond are frequently referred to as electrons.

In this state, one half-filled p orbital from each participating atom overlaps head-on along the internuclear axis.

Pi bonds are generated by the sideways positive (same phase) overlap of atomic orbitals parallel to the internuclear axis. The axes of the atomic orbitals are parallel to each other during bond formation, while the overlapping is perpendicular to the internuclear axis.

Why do quartz and glass both have very high melting points?

please can someone give an explanation

Answers

Covalent bonding is present in Quartz. Covalent bonds result in a high melting point. Covalent solids are insoluble in most solvents.

Why does quartz have such a high melting point?

Quartz is very hard to melt because quartz is unsteady above 870 Celsius, and molten silica is wobbling below 1713 Celsius. In the interval between 870 and 1713 degrees, quartz tends to change to tridymite or cristobalite, not melt. It is hard to heat quartz to melt, in the region of 1650 Celsius

Melting point: The melting point of quartz is higher than 1700°C. Curie temperature for alpha and beta quartz: The Curie warmth for quartz is 573°C.

So we can conclude that Crystal quartz has a very particular melting point. Because quartz glass is a single component it doesn't form eutectics

\(1mole\text{ of }C_4H_{10}=6.02\times10^{23}molecules\)

We are to determine the moles of 5.50 x 10^24 molecules of butane. This is expressed as:

\(\begin{gathered} mole\text{ of }C_4H_{10}=\frac{5.50\times10^{24}}{6.02\times10^{23}} \\ mole\text{ of C}_4H_{10}=0.914\times10^{24-23} \\ mole\text{ of C}_4H_{10}=0.914\times10 \\ mole\text{ of C}_4H_{10}=9.14moles \end{gathered}\)

Answers

When 4.50 g of iron iodide is dissolved in 100 ml of a 0.2M aqueous solution of silver nitrate, the final molarity of iodide anion is 0.415M

We have to first obtain the number of moles of iron iodide (FeI₂)

Molar mass of FeI₂= 310 g/mol

So, number of moles of FeI₂ = 3.40/310 = 0.011 mol

Volume of solution = 100mL or 0.1L

Concentration of AgNO₃ = 0.20 M

number of moles of AgNO3 =  0.20M  x 0.1L = 0.02 mol

The balanced equation of the reaction is

2AgNO₃ + FeI₂ -------> 2AgI + Fe(NO₃)₂

Amount of excess FeI₂ = 0.0525 -  0.011 = 0.0415mol

Therefore, Concentration of excess iodide in solution

= Concentration of excess FeI₂/volume of solution

= 0.0415mol /0.1

An endothermic reaction is a melting solid

What is an enthalpy change?

Enthalpy (H) is a thermodynamic state function that accounts for the internal energy of a system plus the work done by or on the system. When a chemical reaction takes place or a physical change occurs, there may be a change in the enthalpy of the system, represented as ΔH (delta H), which is the difference between the enthalpy of the products and the enthalpy of the reactants.

If ΔH is negative, it means that the reaction or process releases heat energy, and is therefore exothermic. If ΔH is positive, it means that the reaction or process absorbs heat energy, and is therefore endothermic. Enthalpy change is usually measured in joules (J) or kilojoules (kJ) per mole of substance involved in the reaction or process.

65g of NaCl are placed in a beaker and enough water is added to fill the beaker to 1 liter. What is the molar out of this solution? Round answer to the nearest hundredths

Answers

The molarity of the solution is 1.11 M (rounded to 2 decimal places). To find the molarity (M) of the solution, we need to know the number of moles of NaCl and the volume of the solution in liters.

How do molality and molarity differ?

Although a solution's molarity is determined by the moles of solute divided by the volume of the solution in litres, a solution's molality is determined by the moles of solute divided by the mass of the solvent in kilogrammes.

The number of moles of NaCl can be calculated using its molar mass and the given mass of NaCl:

Number of moles = mass / molar mass

The molar mass of NaCl is 58.44 g/mol (22.99 g/mol for Na + 35.45 g/mol for Cl).

Number of moles of NaCl = 65 g / 58.44 g/mol = 1.1138 mol (rounded to 4 decimal places)

The volume of the solution is given as 1 liter.

Now we can use the formula for molarity:

Molarity (M) = number of moles / volume (in liters)

M = 1.1138 mol / 1 L = 1.1138 M (rounded to 2 decimal places)

Answers

Suppose the radius of an atom in a simple cubic unit cell is 0.17 nm. 0.34 nm is the edge length of the unit cell.

In a simple cubic unit cell, the atoms are arranged in a cube with one atom at each corner. The distance from the center of an atom to the edge of the cube is half of the edge length. Therefore, the edge length of the unit cell can be calculated as twice the radius of the atom:

A body-centered cubic unit cell has one atom in the centre and atoms at each of the cube's four corners. We must know the separation between atoms situated at the opposite corners of the cube in order to calculate the edge length of the unit cell.

Think of a diagonal line joining the cube's two opposed corners while traversing its centre. The hypotenuse of a right triangle with two sides equal to the edge length of the unit cell might be imagined as being this diagonal line.
\(Edge length = 2radius\)
Edge length = 2 x 0.17 nm
