If you ran the reaction for this experiment and began with 65.0 mmol of isopentyl alcohol, how many grams of isopentyl acetate could you theoretically produce assuming only a 77.0% attainable yield

Answer:

5 × 10⁵ molecules (500,000 molecules)

Explanation:

Step 1: Convert 3 × 10⁻¹⁶ g to moles

We will use the molar mass of TCDD (321.97 g/mol).

3 × 10⁻¹⁶ g × 1 mol/321.97 g = 9 × 10⁻¹⁹ mol

Step 2: Convert 9 × 10⁻¹⁹ mol to molecules

The required conversion factor is Avogadro's number (6.02 × 10²³ molecules/mol).

9 × 10⁻¹⁹ mol × 6.02 × 10²³ molecules/1 mol = 5 × 10⁵ molecules

Introducción:

La designación de los compuestos orgánicos puede hacerse utulizando alguno de los

siguientes sistemas:

a) Mediante nombres triviales o comunes, que expresen alguna propiedad característica

(sabor, color, acción fisiológica, etc.) o hagan referencia a la materia de la cual se extrajo el

compuesto.

b) Mediante nombres racionales que proporcionen una idea de su constitucion química y

destaquen sus analogías estructurales.

La necesidad de una nomenclatura sistemática, que expresara en forma clara, conforme

a normas precisas, el nombre y la estructura de los compuestos orgánicos, ha sido motivo de

preocupación permanente y observada a través de los numerosos congresos internacionales

que, al efecto, se han realizado en diversas oportunidades.

Las bases del actual sistema de nomenclatura fueron establecidas por una comisión que

se reunió en Ginebra en 1892. Posteriormente, fue perfeccionado y ampliado por el Comité de

Nomenclatura de la Unión Internacional de Química Pura y Aplicada, por lo que se conoce

como sistema I.U.P.A.C. (International Union of Pure and Applied Chemistry).

En las reglas aprobadas se ha tratado de introducir los menores cambios posibles a la

terminología universalmente adoptada. El sistema tiene la necesaria flexibilidad como para

adaptar la forma precisa de las palabras, de las terminaciones, etc. a las características de

distintos idiomas.

El nombre de los hidrocarburos consta de tres partes: a) la raíz, que indica el esqueleto

carbonado; b) la terminación o sufijo, que indica el grado de saturación, y c) el prefijo que

diferencia las distintas estructuras isoméricas (distintas estructuras construidas con exactamente

los mismos átomos).

Ej.: CH3-CH2-CH2-CH2-CH3 pentano (tambien llamado n-pentano)

penta: raíz que señala el número de átomos de carbono que componen la cadena principal

del compuesto.

-ano: sufijo que indica que el hidrocarburo es saturado

The answer is attached below

Explanation:

The answer is the photo attached

Answer:

a. 9.2

b. 4.4

c. 6.3

Explanation:

In order to calculate the pH of each solution, we will use the definition of pH.

pH = -log [H⁺]

(a) [H⁺] = 5.4 × 10⁻¹⁰ M

pH = -log [H⁺] = -log 5.4 × 10⁻¹⁰ = 9.2

Since pH > 7, the solution is basic.

(b) [H⁺] = 4.3 × 10⁻⁵ M

pH = -log [H⁺] = -log 4.3 × 10⁻⁵ = 4.4

Since pH < 7, the solution is acid.

(c) [H⁺] = 5.4 × 10⁻⁷ M

pH = -log [H⁺] = -log 5.4 × 10⁻⁷ = 6.3

Since pH < 7, the solution is acid.

Answer:

B) ethers

Explanation:

The functional group of an organic compound defines its specificity. The functional group is responsible for the chemical behavior of an organic compound. For example, alkenes are known to have a carbon-carbon double bond (C=C) functional group.

Likewise, organic compounds known as ETHERS are known to possess an ethoxy functional group i.e. oxygen atom bonded to two alkyl groups (R- OR; where R is an alkyl group). Members of ether functional group includes dimethyl ether (CH3-O-CH3), diethyl ether (C2H5-O-C2H5).

Answer:

Neither Tech A nor B is correct

Explanation:

Combustion is a chemical reaction that occurs when a chemical molecule(s) interacts quickly with oxygen and produces heat.

When hydrocarbon undergoes a complete combustion reaction, they produce water and CO2.

Tech B is also incorrect because the main purpose of a catalytic converter is to accelerate and speed up the chemical reaction rates, Hence, they are not involved in chemical reaction formation. Catalytic converters are utilized as a control device in exhaust emission to lessen the effect of toxic gas fumes.

Answer:

The pressure law states that for a constant volume of gas in a sealed container the temperature of the gas is directly proportional to its pressure. ... This means that they have more collisions with each other and the sides of the container and hence the pressure is increased.

The temperature of the gas is directly proportional to its pressure.

The ideal gas equation can be given as:

PV = nRT

where P =pressure, V = volume, n = moles of gas, R = rydberg constant, and T = temperature.

The pressure law states that for a constant volume of gas in a container, the temperature of the gas is directly proportional to its pressure which means there are more collisions with each other and the sides of the container and hence the pressure is increased.

Answer:

The amount of CH3OH present in the mixture would decrease

Explanation:

According to Le Cha-telier's principle, when a reaction is in equilibrium and one of the constraints that influence the rate of reactions is applied, the equilibrium would shift so as to neutralize the effects of the constraint.

In this case, looking at the equation of the reaction:

2H2 + CO <------> CH3OH + heat

the total number of moles on the reactant's (left hand) side is 3 (2+1) while on the product's (right hand) side, it is 1. If the pressure on the system is increased, more CH3OH (and less of H2 and CO) will be produced because its side has the lower number of moles out of the two sides.

If the pressure on the system is otherwise lowered, more of H2 and CO would be produced while the amount of CH3OH present would gradually decrease.

Answer:

the answer is glu and I know

The residue that has been drawn incorrectly is option (B) i.e. glu .

Glutathione consists of a glutamate residue linked to cysteine via its γ-carboxyl rather than the α-carboxyl group and followed by a conventional peptide bond between cysteine and glycine.

It plays an important role in maintaining the proper ratio of oxidized to reduced forms of metabolically important thiols such as coenzyme A.

It also provides reducing equivalents that detoxify reactive oxygen species such as peroxides.

The tripeptide is  regenerated through the concerted action enzymes in the so-called γ-glutamyl cycle.

The residue that has been drawn incorrectly is glutamate residue ,hence option (B) is correct.

Lewis base: any species that can donate a pair of electrons and form a coordinate covalent bond. ligand: molecule or ion that surrounds a transition metal and forms a complex ion; ligands act as Lewis bases

Answer:

a. True

Explanation:

An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.

Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.

A chemical reaction can be defined as a chemical process which typically involves the transformation or rearrangement of the atomic, ionic or molecular structure of an element through the breakdown and formation of chemical bonds to produce a new compound or substance.

Hydrogen is the simplest chemical element that exists. The symbol for the chemical element hydrogen is "H" and it is a colourless, tasteless, odorless, and highly flammable gas.

It is a chemical element found in group (1) of the periodic table and as such it has one (1) electron in its outermost shell. Thus, hydrogen has an atomic number of one (1) and a single valence electron because it has only one (1) proton and one (1) electron in its nucleus.

In Stoichiometry, two hydrogen atoms interact to form a hydrogen molecule, with each atom having a single electron in the 1S orbital. These hydrogen atoms react with each other due to the presence of a balanced attractive and repulsive force, which produces a strong covalent bond (H-H) in the hydrogen molecule.

Energy is released in the form of heat when the electrons in the orbitals of the two (2) hydrogen atoms form a covalent bond (H-H); thus, it's an exothermic chemical reaction.
