The reaction is not balanced

Given

Reaction

2Fe(s)+3O₂(g)⇒2Fe₂O₃(s)

Required

The number of atoms

Solution

In a balanced chemical equation, the number of atoms in the compound that reacts (the reactants and products) will have the same number

Reactants : Fe(s)+O₂(g)

Fe = 2 atoms

O = 3 x 2 = 6 atoms

Products : Fe₂O₃(s)

Fe = 2 x 2 = 4 atoms

O = 2 x 3 = 6 atoms

The reaction is not balanced because the number of Fe atoms is not the same

The balanced reaction should be:

4Fe(s)+3O₂(g)⇒2Fe₂O₃(s)

D. all of the above often forms sedimentary rock.

All of the options listed often contribute to the formation of sedimentary rocks. Sedimentary rocks are formed from the accumulation and consolidation of sediments, which are particles or fragments of pre-existing rocks or organic material.

A. Mud and sand: Sedimentary rocks such as shale, mudstone, and sandstone are primarily composed of compacted and cemented mud and sand particles, respectively. Over time, these particles settle and undergo compaction and lithification processes to form sedimentary rocks.

B. Plant and animal remains: Organic matter, including plant and animal remains, can accumulate in certain environments such as swamps, lakes, and marine environments. Over time, these organic materials may undergo partial decomposition and become incorporated into sediment layers. Under specific conditions, this organic material can be preserved and eventually transformed into coal, oil, or natural gas. These substances can be found in sedimentary rocks such as coal beds or oil shale.

C. Chemicals on the ocean floor: Sedimentary rocks can also form from the precipitation of dissolved chemicals in bodies of water, including the ocean. As water evaporates or becomes oversaturated with certain minerals, these minerals can precipitate and settle on the ocean floor. Over time, these accumulated minerals can compact and form sedimentary rocks such as limestone, gypsum, or rock salt.

Therefore, all of the options mentioned (mud and sand, plant and animal remains, and chemicals on the ocean floor) contribute to the formation of sedimentary rocks through different geological processes.

The mass percent of dissolved H₂S in the solution is 18.8%, when solubility is given as 258ml dissolving in 100 grams of water at STP.

Initially, we would determine the mass of H₂S that dissolves in 100 g of water:

According to the solubility, 258 mL of H₂S gas dissolves in 100 g of water at STP.

Also, the density of H₂S gas at STP = 0.08988 g/mL.

Therefore, the mass of H₂S (solute) that dissolves in 100 g of water is:

258 mL H₂S x 0.08988 g/mL

= 23.19 g H₂S

Total mass of the solution:

= 100 g of water + 23.19 g of H₂S

= 123.19 g.

The mass percent of H₂S in the solution is:

= Mass of the solute/mass of the solution x 100

= (23.19 g H₂S / 123.19 g solution) x 100% = 18.8%

Answer:

Oxygen Doesn't change

However, Li is oxidized (0 to +1), Na is reduced (+1 to 0)

Explanation:

On reactant side, Oxygen has -2 oxidation charge because we know common oxidation states such as oxygen -2, hydrogen +1 etc.

So NaOH, O is -2, H is +1, so Na has to be +1 to equal total charge of compound

In product side, LiOH, again O has to be -2, H is +1, so Li +1 as well..

We see that oxygen oxidation state doesn't change. However, for Li it becomes oxidized going from 0 to +1 whereas, Na is reduced going from +1 to 0.

Explanations:

(i) Moles for K

mass = 89.3% = 89.3g

Mol. mass K =39.0983g/mol

∴ n = mass/molmass

=89.3/39.0988

=2.28 moles

(ii) Moles for N

mass = 10.7% = 10.7 g

Mol. mass N =14.0067g/mol

∴ n = mass/molmass

=10.7g/ 14.0067g/mol

=0.76 moles

• K= 2.28 /0.76 = 2.9898240669737 ≈ 3

• N=0.76/0.76 = 1

Answer:

\(\boxed {\boxed {\sf SO_3}}\)

Explanation:

An empirical formula shows the smallest whole-number ratio of the atoms in a compound.

So, we must calculate this ratio. Since we are given the amounts of the elements in moles, we can do this in just 2 steps.

The first step is division. We divide the amount of moles for both elements by the smallest amount of moles.

There are 0.300 moles of sulfur and 0.900 moles of oxygen. 0.300 is smaller, so we divide both amounts by 0.300

The next step is writing the formula. We use the numbers we just found as the subscripts. These numbers go after the element's symbol in the formula. Remember sulfur is S and there is 1 mole and oxygen is O and there are 3 moles.

This formula is technically correct, but we typically remove subscripts of 1 because no subscript implies 1 representative unit.

The statements that does not support the Kinetic Molecular Theory is (option A) the particles of an ideal gas are separated by short distances, compared to their size.

The kinetic molecular theory is a scientific model that explains the behavior of gases based on the motion of their constituent particles. It makes several assumptions about the behavior of gas molecules and how they interact with each other and their surroundings.

In an ideal gas, the particles are considered to be point masses that have negligible volume and do not interact with each other except through elastic collisions.

Therefore, the particles of an ideal gas are considered to be separated by long distances, because there is no attraction or repulsion between the particles, and they move freely in a random motion in the available volume of the container.

The reaction of ethanol catalyzed by alcohol dehydrogenase produces acetaldehyde (CH₃CHO) and NADH. Option A and D is correct.

Alcohol dehydrogenase is an enzyme that plays a crucial role in the metabolism of alcohol (specifically ethanol) in living organisms. It catalyzes the oxidation of alcohols, including ethanol, by removing hydrogen atoms from the alcohol molecule.

The overall reaction will be represented as follows;

Ethanol + NAD⁺ → Acetaldehyde + NADH + H⁺

Alcohol dehydrogenase is an enzyme that facilitates the oxidation of ethanol (CH₃CH₂OH) to acetaldehyde (CH₃CHO). In this reaction, NAD⁺ acts as a coenzyme and is reduced to NADH, which means it gains a hydride ion (H⁻). Simultaneously, ethanol loses two hydrogen atoms, resulting in the formation of acetaldehyde. The reaction will also releases a proton (H⁺).

Answer: Ionic attractions

Explanation:

Ionic bonding is a type of chemical bond that involves the electrostatic attraction between oppositely charged ions.

Dehydration synthesis is a type of chemical reaction in which two molecules are joined together by the removal of a water molecule. This type of reaction is often used to build polymers from monomers.

In dehydration synthesis, a hydrogen atom from one monomer is joined to an oxygen atom from another monomer, with the release of a water molecule. This reaction is also known as condensation reaction.

Dehydration synthesis is a reversible reaction, meaning that the polymer can be broken down into its monomers by adding water. This is important for the body to be able to break down and recycle macromolecules.

2. Name the specific covalent bond formed between monomers (subunits) of:

Amino acids: The specific covalent bond formed between amino acids is called a peptide bond. The peptide bond is formed by the condensation of two amino acids, with the release of a water molecule.

Monosaccharides: The specific covalent bond formed between monosaccharides is called a glycosidic bond. The glycosidic bond is formed by the condensation of two monosaccharides, with the release of a water molecule.

Nucleotides: The specific covalent bond formed between nucleotides is called a phosphodiester bond. The phosphodiester bond is formed by the condensation of three nucleotides, with the release of two water molecules.

The peptide bond is the main type of bond that holds amino acids together in proteins. The glycosidic bond is the main type of bond that holds monosaccharides together in carbohydrates. The phosphodiester bond is the main type of bond that holds nucleotides together in nucleic acids.

These bonds are all covalent bonds, which means that they are formed by the sharing of electrons between atoms. The strength of these bonds varies, but they are all strong enough to hold the monomers together in the polymers.

The specific type of covalent bond that is formed between monomers depends on the type of polymer. For example, the peptide bond is only formed between amino acids, while the glycosidic bond is only formed between monosaccharides.

The formation of these covalent bonds is an important part of the synthesis of macromolecules. These bonds are what give macromolecules their structure and their properties.

The standard emf of the  voltaic cell based on Ag+(aq)/Ag(s) and Fe3+(aq)/Fe2+(aq) half-cells is 0.03 V.

To determine the reactions at the cathode and anode, we need to know the standard reduction potentials of the given half-cells. The standard reduction potentials are as follows:

Ag+(aq) + e- → Ag(s) E° = +0.80 V
Fe3+(aq) + e- → Fe2+(aq) E° = +0.77 V
Since the higher reduction potential will occur at the cathode and the lower one at the anode, we have:
Cathode reaction: Ag+(aq) + e- → Ag(s)
Anode reaction: Fe3+(aq) + e- → Fe2+(aq)
The cathode reaction involves the reduction of silver ions to silver metal, and the anode reaction involves the reduction of ferric ions to ferrous ions. And the standard emf of the cell is:

E°cell = E°cathode - E°anode

E°cell = +0.80 V - (+0.77 V)

E°cell = 0.03 V

In this voltaic cell, the cathode reaction is Ag+(aq) + e- → Ag(s), and the anode reaction is Fe3+(aq) + e- → Fe2+(aq). The standard emf of the cell is 0.03V.

A voltaic cell is based on Ag+(aq)/Ag(s) and Fe3+(aq)/Fe2+(aq) half-cells. The cathode reaction is \(Ag^+(aq) + e^{-}\ - > Ag(s)\) and the anode reaction is \(Fe^{3+}(aq)\ - > Fe^{2+}(aq) + e^{-}\).

Determine the cathode and anode reactions

To determine the cathode and anode reactions in the voltaic cell based on the \(Ag^+(aq)/Ag(s)\ and\ Fe^{3+}(aq)/Fe^{2+}(aq)\) half-cells, we need to compare the reduction potentials of each half-reaction. The reaction with the higher reduction potential will occur at the cathode (where reduction takes place), while the reaction with the lower reduction potential will occur at the anode (where oxidation takes place).

The standard reduction potentials for the half-reactions are as follows:

\(Ag^+(aq) + e^{-}\ - > Ag(s) \ \ \ \ \ \ \ \ E\° = +0.80 V\)

\(Fe^{3+}(aq) + e^{-} \ - > Fe^{2+}(aq) \ \ \ \ \ \ \ \ E\° = +0.77 V\)

Since the standard reduction potential for \(Ag^+(aq)/Ag(s)\) is higher than that of \(Fe^{3+}(aq)/Fe^{2+}(aq)\), the \(Ag^+(aq)/Ag(s)\) half-reaction will occur at the cathode (reduction) and the \(Fe^{3+}(aq)/Fe^{2+}(aq)\) half-reaction will occur at the anode (oxidation).

A.) Cathode reaction:

\(Ag^+(aq) + e^{-}\ - > Ag(s)\)

B.) Anode reaction:

\(Fe^{3+}(aq)\ - > Fe^{2+}(aq) + e^{-}\)

It's important to note that the oxidation half-reaction is typically written in the reverse direction (as an oxidation) to emphasize the loss of electrons.

Therefore, the cathode reaction is \(Ag^+(aq) + e^{-}\ - > Ag(s)\) and the anode reaction is \(Fe^{3+}(aq)\ - > Fe^{2+}(aq) + e^{-}\).
