How many kilojoules of heat will be released when exactly 1 mole of iron, Fe, is burned to form Fe2O3 (s) at standard state conditions? (Use Appendix G in text.)
412 kJ
824 kJ
1650 kJ
The heat of formation, or enthalpy of formation, of a compound, can be found in a reference such as the appendix of a textbook or a thermochemistry table. The heat of the formation of Fe2O3(s) is -824 kJ/mol. It represents the heat change that occurs when one mole of Fe2O3 is formed from its elements under standard state conditions. So the answer is 824 kJ will be released.
The heat of formation, also known as enthalpy of formation, is the heat energy change that occurs when a substance is formed from its element under standard state conditions. It is usually expressed in kJ/mol.
When we are dealing with the combustion of a substance, this value is used to determine how much heat is released or absorbed in the process. In this case, the substance is iron and we need to form Fe2O3.
To find the amount of heat released, we can use the heat of formation value of Fe2O3, which is -824 kJ/mol.
Since the value is negative, this means that 824 kJ of heat is released when 1 mole of Fe is burned to form Fe2O3 under standard state conditions.
It is also important to note that these values are usually provided at a specific temperature, usually at 25 degrees Celsius, and standard pressure.

A solution is made by dissolving 18.1 g of HCl in 721 mL of water. Calculate the pH of the solution.
Taking into account the definition of pH, the pH of the solution is 0.16.
Definition of pHpH is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.
The pH is defined as the negative base 10 logarithm of the activity of hydrogen ions:
pH= - log [H⁺]
pH in this caseA solution is made by dissolving 18.1 g of HCl in 721 mL(or 0.721 L) of water. Being the molar mass of HCl 36.45 g/mole, the amount of moles of HCl can be calculated as:
amount of moles= 18.1 g÷ 36.45 g/mole
amount of moles= 0.4966 moles
HCl is a strong acid, meaning it dissociates completely. So:
[HCL]= [H⁺]= amount of moles÷ volume
[HCL]= [H⁺]= 0.4966 moles÷ 0.721 L
[HCL]= [H⁺]= 0.6887 moles/L
Then, the pH can be calculated as:
pH= - log (0.6887 moles/L)
pH= 0.16

In a reaction, 2-methylbutan-1-ol is oxidised by potassium dichromate. Write equations for the two oxidation steps of this reaction and then name and draw (as displayed
formula) the two products of this reaction.
The oxidation of 2-methylbutan-1-ol (also known as isobutyl alcohol) by potassium dichromate is a two-step process. In the first step, the alcohol is oxidized to an aldehyde:
2-methylbutan-1-ol + K₂Cr₂O₇ + H₂SO₄ (oxidising agent) → 2-methylbutanal + K₂SO₄ + Cr₂(SO₄)3 + H₂O
In the second step, the aldehyde is further oxidized to a carboxylic acid:
2-methylbutanal + K₂Cr₂O₇ + H₂SO₄ (oxidizing agent) → 2-methylbutanoic acid + K₂SO₄ + Cr₂(SO₄)3 + H₂O
The first product is 2-methylbutanal, the structural formula of which is
H₃C-C(H)(OH)-CH₃
The second product is 2-methylbutanoic acid, the structural formula of which is
H₃C-C(H)(COOH)-CH₃
What is the reaction about?In the first step of the reaction, 2-methylbutan-1-ol is oxidized to 2-methylbutanal by potassium dichromate (K₂Cr₂O₇) in the presence of sulfuric acid (H₂SO₄) as a catalyst.
The sulfuric acid catalyzes the breakdown of potassium dichromate into its active form, chromic acid (H₂CrO₄), which is the actual oxidizing agent in this reaction.
In the second step, the aldehyde produced in the first step is further oxidized to a carboxylic acid by the same reagents (K₂Cr₂O₇ and (H₂SO₄), this time the aldehyde is oxidized by the chromic acid to form the carboxylic acid.
In the second step, the aldehyde group (C=O) is oxidized to a carboxyl group (COOH) and a hydrogen atom is lost from the adjacent carbon atom. This results in the formation of the carboxylic acid.

Explain the principles behind an acid-base titration. What is an indicator?
An acid–base titration is a method of quantitative analysis for determining the concentration of an acid or base by exactly neutralizing it with a standard solution of base or acid having known concentration. A pH indicator is used to monitor the progress of the acid–base reaction.
There is no change in the concentration of the reactants or the products.
When a reversible process reaches equilibrium,
The forward reaction rate is the same as the backward reaction rate.
The quantity of product being formed is therefore equal to the quantity of reactant being formed in a given amount of time.
Therefore, for a reversible reaction at equilibrium, both the reactant concentration and the product concentration are constant.
Indicators can be used to roughly determine the equivalence point of an acid-base titration as this colour shift only happens over a narrow pH range.

i figured it out the answer is 107.1740.
The mass of the sulfur that has been produced is 13.44 g.
What is the mass of the sulfur that is produced?We have to know that we have to look closely at the reaction equation that have been shown in the question as this would help nus to obtain the answer that we are looking for.
Now we have;
Number of moles of sulfur dioxide = 76 g/64 g/mol = 1.19 moles
Number of moles of hydrogen sulfide = 76 g/34 g/mol = 2.24 moles
If 8 moles of sulfur dioxide reacts with 16 moles of sulfur dioxide
1.19 moles of sulfur dioxide would react with 1.19 * 16/8
= 2.38 moles
Hence the hydrogen sulfide is the limiting reactant
Now;
16 moles of hydrogen sulfide produces 3 moles of sulfur
2.24 moles of hydrogen sulfide would produce
2.24 * 3/16
= 0.42 moles
Mass of sulfur produced = 0.42 moles * 32 = 13.44 g

What mass of solid La(I03)3 (663.6 g/mol) is formed when 50.0 mL of 0.250 M La³+ are mixed
with 75.0 mL of 0.302 M I03?
Answer:
To solve this problem, you need to use the mole ratios between the reactants to calculate how many moles of each reactant are used. The mole ratio between La³+ and La(I03)3 is 1:1 because there is one mole of La³+ for every mole of La(I03)3 that is produced. Similarly, the mole ratio between I03 and La(I03)3 is 3:1 because there are 3 moles of I03 for every mole of La(I03)3.
Using these mole ratios, you can calculate how many moles of each reactant are used in the reaction. First, you need to convert the volumes of the reactants to moles using their concentrations. The number of moles of La³+ is given by:
n(La³+) = (50.0 mL) * (0.250 M) = 12.5 moles
The number of moles of I03 is given by:
n(I03) = (75.0 mL) * (0.302 M) = 22.6 moles
Since the mole ratio between La³+ and La(I03)3 is 1:1, the number of moles of La(I03)3 produced is equal to the number of moles of La³+ used, which is 12.5 moles. The mass of La(I03)3 produced is then given by:
m(La(I03)3) = (12.5 moles) * (663.6 g/mol) = 8292.0 g
So, a mass of 8292.0 g of La(I03)3 is formed when 50.0 mL of 0.250 M La³+ are mixed with 75.0 mL of 0.302 M I03.

Account for the low reactivity of chlorobenzene toward Ag+
The resonance structures that result form the reaction of chlorobenzene toward Ag^+ are unstable hence the low reactivity.
Why is there low reactivity?Let us recall that the kind of reaction that is going to occur here is the nucleophilic reaction. The implication of that is that the center that is going to be attacked is a center that is positive.
We now have to look at the structure of the chlorobenzene as we can see from the structures of the resonance of the compound that have been shown in the image attached.
The resonance structures that are formed by the compound are not stable and such the attacked does not lead to the production of chemical species that are stable and this is why the reactivity of the chlorobenzene towards the sliver ion is low.
