Write the net ionic equation for the below chemical reaction:

(c): \(FeCl_3+3NH_4OH\rightarrow Fe(OH)_3+3NH_4CI\)

Answer: The net ionic equation is \(Fe^{3+}(aq)+3OH^{-}(aq)\rightarrow Fe(OH)_3(s)\)

Explanation:

Net ionic equation is defined as the equations in which spectator ions are not included.

Spectator ions are the ones that are present equally on the reactant and product sides. They do not participate in the reaction.

(c):

The balanced molecular equation is:

\(FeCl_3(aq)+3NH_4OH(aq)\rightarrow Fe(OH)_3(s)+3NH_4Cl(aq)\)

The complete ionic equation follows:

\(Fe^{3+}(aq)+3Cl^-(aq)+3NH_4^+(aq)+3OH^{-}(aq)\rightarrow Fe(OH)_3(s)+3NH_4^+(aq)+3Cl^-(aq)\)

As ammonium and chloride ions are present on both sides of the reaction. Thus, they are considered spectator ions.

The net ionic equation follows:

\(Fe^{3+}(aq)+3OH^{-}(aq)\rightarrow Fe(OH)_3(s)\)

An exothermic reaction is a chemical reaction that releases energy in the form of heat, light, or sound, whereas an endothermic reaction is a chemical reaction that absorbs energy from its surroundings in the form of heat.

In an exothermic reaction, the reactants have more energy than the products, which means that energy is released during the reaction. In contrast, in an endothermic reaction, the products have more energy than the reactants, which means that energy is absorbed during the reaction.

Examples of exothermic reactions include combustion, such as the burning of wood or gasoline, and the reaction between vinegar and baking soda, which produces carbon dioxide gas. An example of an endothermic reaction is the melting of ice, which absorbs heat from its surroundings to convert solid ice into liquid water. An overview was given based on incomplete information.

What is buffer ?

Buffer, in chemistry, usually a solution containing acids and bases or salts that tends to maintain a constant concentration of hydrogen ions. An ion is an atom or molecule that has lost or gained one or more electrons. A common buffer is a solution of acetic acid (CH3COOH) and sodium acetate. In aqueous solution, sodium acetate completely dissociates into sodium (Na+) and acetate (CH3COO-) ions. Buffer solutions with different hydrogen ion concentrations can be prepared by varying the buffer ratio and choosing acids of appropriate intrinsic strength. Commonly used buffers include phosphate, citrate, or borate and their salts

The direction of heat transfer between two samples of carbon depends on their temperature difference, and not solely on their average kinetic energy. While the average kinetic energy of a substance is related to its temperature, it is not the determining factor for the direction of heat transfer.

When two samples of carbon come into contact, a heat transfer will occur between sample A and sample B. The direction of heat transfer is dependent on the temperature difference between the samples. Heat transfer always flows from a hotter object to a cooler object, so if sample A is hotter than sample B, heat will flow from A to B. If sample B is hotter than sample A, heat will flow from B to A.
The average kinetic energy of the molecules in a substance is related to its temperature. The higher the average kinetic energy, the higher the temperature of the substance. However, the average kinetic energy does not determine the direction of heat transfer.
It is possible for a substance with a lower average kinetic energy (and therefore a lower temperature) to transfer heat to a substance with a higher average kinetic energy (and therefore a higher temperature). This can occur if the substance with the lower temperature has a greater heat capacity, which means it can absorb more heat without a significant increase in temperature.

Exercises Example 6. How Many Moles Of Carbon Atoms And How Many Carbon Atoms Are Contained In 1.0 G Of C,H,OH

Explanation:

The mass of the propane that would have the same number of carbon atoms is  0.63 g.

We know that we can be able to obtain the number of the carbon atoms by the use of the simple stoichiometry of the reaction as we have it in the question that we have been asked here.

We can see that we have the molar mass of the ethanol as we can see as 46 g/mol. We have to obtain the number of moles of the ethanol that we have in the compound as follows;

Number of moles = 1 g/ 46 g/mol = 0.022 moles

Number of the carbon atoms that we have is; 0.022 moles * 2 * 6.02 * 10^23 = 2.6 * 10^22 atoms

Now the number of the grams of the propane that we have is;

2.6 * 10^22  = x * 3 * 6.02 * 10^23

Where x is the number of moles present

x =  2.6 * 10^22 / 1.806 * 10^24

x = 1.44 * 10^-2 moles

x = 0.0144 moles

Given that the molar mass of the propane is 44 g/mol

mass  =  0.0144 moles * 44 g/mol

Mass = 0.63 g

If there are more products than reactants, that means the reaction has shifted towards the left, which is the backward direction. If there are more reactants than products, that means the reaction has shifted towards the right, which is the forward direction.

At equilibrium, the number of moles of \(Cl_2\) (g) will be 0.2025 mol.

1: Write the balanced chemical equation:

\(C_O\)(g) + \(Cl_2\)(g) ⟶ \(C_OCl_2\)(g)

2: Set up an ICE table to track the changes in moles of the substances involved in the reaction.

Initial:

\(C_O\)(g) = 0.3500 mol

\(Cl_2\)(g) = 0.05500 mol

\(C_OCl_2\)(g) = 0 mol

Change:

\(C_O\)(g) = -x

\(Cl_2\)(g) = -x

\(C_OCl_2\)(g) = +x

Equilibrium:

\(C_O\)(g) = 0.3500 - x mol

\(Cl_2\)(g) = 0.05500 - x mol

\(C_OCl_2\)(g) = x mol

3: Write the expression for the equilibrium constant (Kc) using the concentrations of the species involved:

Kc = [\(C_OCl_2\)(g)] / [\(C_O\)(g)] * [\(Cl_2\)(g)]

4: Substitute the given equilibrium constant (Kc) value into the expression:

1.2 x \(10^3\) = x / (0.3500 - x) * (0.05500 - x)

5: Solve the equation for x. Rearrange the equation to obtain a quadratic equation:

1.2 x \(10^3\) * (0.3500 - x) * (0.05500 - x) = x

6: Simplify and solve the quadratic equation. This can be done by multiplying out the terms, rearranging the equation to standard quadratic form, and then using the quadratic formula.

7: After solving the quadratic equation, you will find two possible values for x. However, since the number of moles cannot be negative, we discard the negative solution.

8: The positive value of x represents the number of moles of \(Cl_2\)(g) at equilibrium. Substitute the value of x into the expression for \(Cl_2\)(g):

\(Cl_2\)(g) = 0.05500 - x

9: Calculate the value of \(Cl_2\)(g) at equilibrium:

\(Cl_2\)(g) = 0.05500 - x

\(Cl_2\)(g) = 0.05500 - (positive value of x)

10: Calculate the final value of \(Cl_2\) (g) at equilibrium to get the answer.

Therefore, at equilibrium, the number of moles of \(Cl_2\) (g) will be 0.2025 mol.

6.02 x \(10^{20\) formula units of MgCl₂ is equal to 0.1 moles of MgCl₂.

To convert formula units of MgCl₂ to moles of MgCl₂, we need to use Avogadro's number, which relates the number of formula units to the number of moles.

Avogadro's number (NA) is approximately 6.022 x 10^23 formula units per mole.

Given that we have 6.02 x 10^20 formula units of MgCl₂, we can set up a conversion factor to convert to moles:

(6.02 x 10^20 formula units MgCl₂) * (1 mol MgCl₂ / (6.022 x 10^23 formula units MgCl₂))

The formula units of MgCl₂ cancel out, and we are left with moles of MgCl₂:

(6.02 x 10^20) * (1 mol / 6.022 x 10^23) = 0.1 mol

Therefore, 6.02 x 10^20 formula units of MgCl₂ is equal to 0.1 moles of MgCl₂.

It's important to note that this conversion assumes that each formula unit of MgCl₂ represents one mole of MgCl₂. This is based on the stoichiometry of the compound, where there is one mole of MgCl₂ for every one formula unit.

Additionally, this conversion is valid for any substance, not just MgCl₂, as long as you know the value of Avogadro's number and the number of formula units or particles you have.

The instantaneous rate of reaction at 17 minutes is approximately -0.178 mol dm⁻³

To find the instantaneous rate of reaction at 17 minutes, we can use the concept of differential calculus and estimate the slope of the tangent line at t=17 on the graph of rate versus time.

To do this, we can use the formula for the slope of a line

slope = (change in y) / (change in x)

In this case, the "y" values are the rates of reaction and the "x" values are the times. We want to find the slope at t=17, so we can choose two points that are very close to t=17, such as t=15 and t=20. Then, we can use these values to estimate the slope at t=17

slope = (rate at 20 min - rate at 15 min) / (20 min - 15 min)

slope = (0.135 - 0.223) / (20 - 15)

slope = -0.178

This slope represents the instantaneous rate of reaction at t=17. However, since it has a negative value, it means that the rate of reaction is decreasing at t=17.

Therefore, the instantaneous rate of reaction at 17 minutes is approximately -0.178 mol dm⁻³
