The total charge on the atom is +1 and the correct option is option 3.

According to the Bohr Atomic model, a small positively charged nucleus is surrounded by revolving negatively charged electrons in fixed orbits.

He concluded that electron will have more energy if it is located away from the nucleus whereas electrons will have less energy if it located near the nucleus.

In a neutral atom, the number of protons is equal to the number of electrons.

Since, this atom has 11 protons and 10 electrons, thus there is one extra protons which gives it a +1 charge.

Therefore, the total charge on the atom is +1 and the correct option is option 3.

A tablet weighing 0.940 g was dissolved in dilute sulphuric acid made up to 250 cm³ with water. 25.0 cm³ of this solution was titrated with 0.00160 M K\(_2\)Cr\(_2\)O requiring 32.5 cm3 of the  K\(_2\)Cr\(_2\)O. 4.17% is the percentage by mass of  \(Fe^{2+}\) in the tablet.

Mass percent is a means to describe a component in a specific combination or to convey a concentration. The mass percentage used to describe the solution composition indicates the mass of solute contained in a given mass of solution. The solute's concentration is specified in terms of mass or moles.

6\(Fe^2+\) + \(Cr_2O_7^{2-}\) + 14\(H^+\) → 6\(Fe^{3+}\) + 2\(Cr^{3+}\)+ 7H\(_2\)O

32.5 cm³x 0.00160 M = 0.052 g of K\(_2\)Cr\(_2\)O\(_7\)

0.052 g / 294.18 g/mol = 0.000177moles of K\(_2\)Cr\(_2\)O

0.000177 mol / 6 = 0.0000295 mol moles of \(Fe^{2+}\)

0.0000295 mol / 0.025 L = 0.00118 M  of  \(Fe^{2+}\)

0.00118 M x 55.845 g/mol x 0.025 L = 0.0392 g of  \(Fe^{2+}\)

thermal shock

Explanation:

the temperatures inside the glass jar should have continued to increase over time. Internal stresses due to uneven heating. This is also known as “thermal shock”.

In general, the thicker the glass, the more prone it will be to breaking due to the immediate differences in temperature across the thickness of glass.

Borosilicate glass is more tolerant of this, as it has a higher elasticity than standard silicon glass.

You may also note that laboratory test tubes and flasks are made with thinner walls, and of borosilicate glass, when designated for heating.

Molecular structure refers to the three-dimensional arrangement of atoms within a molecule.

This arrangement plays a significant role in determining the properties and behavior of a compound, such as its reactivity, polarity, and solubility. The molecular structure is determined by the type, number, and arrangement of atoms, as well as the bonding between them. The most common types of molecular structures include linear, trigonal planar, tetrahedral, and octahedral. The study of molecular structure is important in a variety of fields, including chemistry, biochemistry, and materials science, and is often analyzed using various experimental techniques such as X-ray crystallography, nuclear magnetic resonance (NMR) spectroscopy, and computational chemistry methods.

Answer:

Double replacement

Explanation:

The phenomenon described in the given question, where some amount of the solid stuck to the weigh paper and was not transferred, is an example of a volumetric error in the preparation of standard solutions.

A standard solution is a solution with a precisely known concentration of an element or a substance. They are prepared to a specific concentration by dissolving a known quantity of a pure substance in a particular solvent in a volumetric flask.

Volumetric errors are a type of systematic error that occurs when preparing standard solutions. They occur due to an error in the volume of solution added or when some of the solute gets lost during the transfer process. As a result, the measured concentration comes out a bit low for this solution.

To avoid such errors, it is essential to pay close attention to the precise amount of the analyte used and be careful while transferring it to the volumetric flask. Any loss of the solid during the transfer process will result in an incorrect concentration of the solution and can lead to incorrect results.

Thus, the correct answers is volumetric error.

The vapor pressure of hexane at 25.00 °C is approximately 0.292 atm.

To calculate the vapor pressure of hexane at 25.00 °C, we can use the Clausius-Clapeyron equation:

\(ln(P2/P1) = (-ΔHvap/R) * (1/T2 - 1/T1)\)

Where:

P1 is the vapor pressure at the boiling point (68.73 °C) (unknown)

P2 is the vapor pressure at the desired temperature (25.00 °C)

ΔHvap is the molar enthalpy of vaporization (28.9 kJ/mol)

R is the ideal gas constant (8.314 J/(mol·K))

T1 is the boiling point temperature in Kelvin (68.73 + 273.15)

T2 is the desired temperature in Kelvin (25.00 + 273.15)

Rearranging the equation, we get:

\(P2/P1 = e^((-ΔHvap/R) * (1/T2 - 1/T1))\)

To find P1, we can rearrange the equation further:

\(P1 = P2 / e^((-ΔHvap/R) * (1/T2 - 1/T1))\)

Substituting the given values into the equation:

\(P1 = P2 / e^((-28.9 kJ/mol / (8.314 J/(mol·K))) * (1/(25.00 + 273.15) - 1/(68.73 + 273.15)))\)

Calculating the right-hand side of the equation and substituting P2 = 1 atm (since it's the standard pressure):

\(P1 = 1 atm / e^((-28.9 kJ/mol / (8.314 J/(mol·K))) * (1/(25.00 + 273.15) - 1/(68.73 + 273.15)))\)

P1 ≈ 0.292 atm

The pH of the mixture is nearly 10.7.

To calculate the pH of the given solution, we need to first consider the ionization of the nitrite ion (NO₂⁻) in water. NO₂⁻ is a weak base, which means that it can accept hydrogen ions (H⁺) from water to form the conjugate acid, nitrous acid (HNO₂).

The equilibrium expression for the ionization of NO₂⁻ in water is:

NO₂⁻ + H₂O ⇌ HNO₂ + OH-

The base dissociation constant, Kb, for NO₂⁻ can be calculated using the ionization constant for its conjugate acid, HNO₂:

Kb = Kw / Ka

where Kw is the ionization constant for water and Ka is the acid dissociation constant for HNO₂. The value of Kw is 1.0 x 10⁻¹⁴ at 25°C.

The value of Ka for HNO₂ is 4.5 x 10⁻⁴. Therefore, the value of Kb for NO₂⁻ can be calculated as:

Kb = Kw / Ka = (1.0 x 10⁻¹⁴) / (4.5 x 10⁻⁴) = 2.2 x 10⁻¹¹

Now, we can calculate the concentration of OH⁻ ions in the solution using the Kb value and the initial concentration of NO₂⁻. Since NaNO₂ is a neutral salt, it will dissociate completely into Na⁺ and NO₂⁻ ions in water. Therefore, the initial concentration of NO₂⁻ is given by:

[NO₂⁻] = mass of NaNO₂ / molar mass of NaNO₂ / volume of solution

[NO₂⁻] = (3.97 g / 68.99 g/mol) / (500 mL / 1000 mL/L) = 0.114 M

Using the Kb value and the initial concentration of NO₂⁻, we can calculate the concentration of OH⁻ ions as follows:

Kb = [HNO₂][OH-] / [NO₂⁻]

[OH-] = Kb x [NO₂⁻] / [HNO₂]

[OH-] = (2.2 x 10⁻¹¹) x (0.114 M) / x

where x is the concentration of HNO₂, which we can assume is small compared to the initial concentration of NO₂⁻

[OH⁻] ≈ (2.2 x 10⁻¹¹ x (0.114 M) / 0.114 M

[OH⁻] = 2.2 x 10⁻¹¹ M

Finally, we can calculate the pH of the solution using the concentration of OH⁻ ions:

pH = 14 - pOH = 14 - (-log[OH⁻]) = 14 - (-log(2.2 x 10⁻¹¹) ≈ 10.7

Therefore, the pH of the solution is approximately 10.7.
