Answer:

1.6x10¹¹ = Kc

Explanation:

For the reaction:

AgCl(s) + 2CN⁻(aq) ⇄ Ag(CN)₂⁻(aq) + Cl⁻(aq)

Kc is defined as:

Kc = [Ag(CN)₂⁻] [Cl⁻] / [CN⁻]²

Ksp of AgCl is:

AgCl(s) ⇄ Ag⁺(aq) + Cl⁻(aq)

Where Ksp is:

Ksp = [Ag⁺] [Cl⁻] = 1.6x10⁻¹⁰

In the same way, Kf of Ag(CN)₂⁻ is:

Ag⁺(aq) + 2CN⁻ ⇄ Ag(CN)₂⁻

Kf = [Ag(CN)₂⁻] / [CN⁻]² [Ag⁺] = 1.0x10²¹

The multiplication of Kf with Ksp gives:

[Ag⁺] [Cl⁻] *  [Ag(CN)₂⁻] / [CN⁻]² [Ag⁺] = Ksp*Kf

[Ag(CN)₂⁻] [Cl⁻] / [CN⁻]² = Ksp*Kf

Obtaining the same expression of the first reaction

That means Ksp*Kf = Kc

1.6x10⁻¹⁰*1.0x10²¹ = Kc

Answer:

The volume of Component 1 is 36 cubic inches.

Explanation:

To calculate the volume of a composite solid, we need to determine the individual volumes of the different components and then add them together.

In this case, the composite solid consists of multiple components with the following dimensions:

Component 1:

Length: 4 inches

Width: 3 inches

Height: 3 inches

To find the volume of Component 1, we multiply the length, width, and height together:

Volume of Component 1 = Length x Width x Height = 4 in x 3 in x 3 in = 36 cubic inches

Therefore, the volume of Component 1 is 36 cubic inches.

Answer:

So the math expression is  

             \(heat  =  \frac{ 35. 7  KJ *  1900 \ gram }{ 1 \ gram }\)

Explanation:

From the question we are told that

  The heat released for 1 gram of reactant consumed is  \(H  =  37.5 \ KJ/g \)

   The mass of reactant considered is  \(m =  1.9 \ kg  =  1900 \  g\)

So  if

             \(37.5 \ KJ \) is produced for  1 gram

Then

              x kJ is produced for  1900 g  

=>   \(x  =  \frac{ 35. 7  KJ *  1900 \ gram }{ 1 \ gram }\)

So the heat released is  

       \(heat  =  \frac{ 35. 7  KJ *  1900 \ gram }{ 1 \ gram }\)

Answer:

Approximately \(21\; \rm g\).

Explanation:

\(\rm H_2SO_4\) (a diprotic acid) reacts with \(\rm NaOH\) (a monoprotic base) at a one-to-two ratio:

\(\rm 2\; NaOH\, (s) + H_2SO_4\, (aq) \to Na_2SO_4\; (aq) + 2\; H_2O\, (l)\).

In other words, if \(n(\mathrm{NaOH})\) and \(n(\mathrm{H_2SO_4})\) represent the number of moles of the two compounds reacted, then:

\(\displaystyle \frac{n(\mathrm{H_2SO_4})}{n(\mathrm{NaOH})} = \frac{1}{2}\).

Look up the relative atomic mass data on a modern periodic table:

Calculate the (molar) formula mass of \(\rm H_2SO_4\) and \(\rm NaOH\):

\(M(\mathrm{H_2SO_4}) = 2 \times 1.008 + 32.06 + 4 \times 15.999 = 98.072\; \rm g \cdot mol^{-1}\).

\(M(\mathrm{NaOH}) = 22.990 + 15.999 + 1.008 = 39.997\; \rm g \cdot mol^{-1}\).

Calculate the number of moles of formula units in that \(33.8\; \rm g\) of \(\rm NaOH\):

\(\begin{aligned}n(\mathrm{NaOH}) &= \frac{m(\mathrm{NaOH})}{M(\mathrm{NaOH})} \\ &= \frac{33.8\; \rm g}{39.997\; \rm g \cdot mol^{-1}} \approx 0.845\; \rm mol\end{aligned}\).

Apply the ratio \(\displaystyle \frac{n(\mathrm{H_2SO_4})}{n(\mathrm{NaOH})} = \frac{1}{2}\) to find the (maximum) number of moles of \(\rm H_2SO_4\) that would react with the \(33.8\; \rm g\) of \(\rm NaOH\):

\(\begin{aligned}n(\mathrm{H_2SO_4}) &= \frac{n(\mathrm{H_2SO_4})}{n(\mathrm{NaOH})} \cdot n(\mathrm{NaOH})\\ &= \frac{1}{2} \times 0.845 \approx 0.4225\; \rm mol\end{aligned}\).

Calculate the mass of that \(0.4225\; \rm mol\) of \(\rm H_2SO_4\):

\(\begin{aligned}m(\mathrm{H_2SO_4}) &= n(\mathrm{H_2SO_4}) \cdot M(\mathrm{H_2SO_4})\\ &= 0.4225 \; \rm mol \times 98.072\; \rm g \cdot mol^{-1} \approx 41.435\; \rm g \end{aligned}\).

When the maximum amount of \(\rm H_2SO_4\) is reacted, the minimum would be in excess. Hence, the minimum mass of

\(62\; \rm g - 41.435\; \rm g \approx 21\; \rm g\) (rounded to two significant figures.)

Explanation:

Usually, metallic bonding is present in metallic elements (E.g Mg). Metallic bonding is described as the attracrion between positive ions and the sea of delocalised electrons.

covalent bonding are usually found in compounds containing only non-metal elements (E.g H20, CO2). Covalent bonding is formed by sharing of electrons.

Ionic bonding is found in compounds containing both metals and non metal elements. (E.g ZnOH2). It is the electrostatic force of attraction between positive and negative charges. Salts are usually ionic compounds.

In the solid state of matter, particles, such as atoms, ions, or molecules, are closely packed and held together by strong intermolecular forces, such as ionic bonds, metallic bonds, or covalent bonds.

In a solid, particles have enough energy to vibrate around fixed positions but do not have enough energy to overcome the attractive forces between them. These attractive forces, also known as cohesive forces, arise from the electrostatic interactions between particles or the sharing of electrons in covalent bonds.

The energy of the particles in a solid is typically much lower than in the liquid or gaseous states, resulting in a fixed arrangement of particles.

The movement of particles in a solid is characterized by vibrations or oscillations around their equilibrium positions.

These vibrations occur due to the thermal energy present in the solid, but the particles remain relatively fixed in their positions due to the strong attractive forces. The amplitude of the vibrations increases with increasing temperature, as the particles gain more thermal energy.

However, the particles in a solid do not have enough energy to break the intermolecular bonds and move freely throughout the entire solid. Instead, they can only move within their local vicinity or lattice positions.

This restricted movement is what distinguishes the solid state from the liquid or gaseous states, where particles have enough energy to overcome intermolecular forces and move more freely.

Triglycerides, Oil, Cholesterol, and Lipids will come under hydrophobic. Carbohydrates, Glucose, Ions, Polar compounds, and water will come under hydrophilic.

Hydrophilic and hydrophobic are terms used to portray the interaction of molecules with water.

Hydrophilic molecules are those that are attracted to water and will generally dissolve in it. These molecules have polar nature, meaning they have a lopsided distribution of electrons, which permits them to frame hydrogen bonds with water molecules.

Hydrophobic molecules are those that repulse water and don't dissolve in it. These molecules have a nonpolar nature, meaning they have an even dispersion of electrons, which doesn't permit them to shape hydrogen bonds with water molecules.

The column 1 has the value of Isotope, column 2 has the value of mass in atomic mass units, and column 3 has the value of abundance and the average atomic mass of strontium is 87.47 amu.

To calculate the average atomic mass of strontium using the given information, we need to multiply the mass of each isotope by its abundance and then sum up these values. Here's the calculation:

Isotope | Mass (amu) | Abundance

^84Sr | 83.913428 | 0.56%

^86Sr | 85.909273 | 9.86%

^87Sr | 86.908902 | 7.00%

^88Sr | 87.905625 | 82.58%

To find the average atomic mass, we multiply each isotope's mass by its abundance (in decimal form) and sum up the values:

Average atomic mass = (\(Mass of ^{84Sr}\) × \(Abundance of^{84Sr}\)) + (\(Mass of ^{86Sr}\)× \(Abundance of^{86Sr}\)) + (\(Mass of ^{87Sr}\) × \(Abundance of^{87Sr}\)) + (\(Mass of ^{88Sr}\) × \(Abundance of^{88Sr}\))

Average atomic mass = (83.913428 amu × 0.0056) + (85.909273 amu × 0.0986) + (86.908902 amu × 0.0700) + (87.905625 amu × 0.8258)

Calculating this expression yields:

Average atomic mass = 0.469901638 + 8.468098826 + 6.08462314 + 72.44409075

= 87.466714354 amu
