if 15 mol C is mixed with 10 mol O2 which reactant is the limiting reactant? Which reactant would be the excess reactant?

Upon dissolving 0.3 moles of HBr in 1 L of water, one should expect an acid-base reaction to occur in the beaker. This reaction can be represented by the equation: HBr (aq) + H2O (l) → H3O+ (aq) + Br- (aq)This equation shows that the HBr molecule dissolves in water to form ions.

The H+ ion, or hydronium ion, combines with water to form the H3O+ ion. The Br- ion remains unchanged since it does not react with water. The resulting solution will be acidic because of the presence of H3O+ ions. The concentration of H3O+ ions will be determined by the extent to which HBr molecules have ionized or dissociated in the water.

This can be calculated using the formula for the ionization constant of water (Kw) and the acid dissociation constant (Ka) of HBr. Kw is equal to 1.0 x 10^-14 at 25°C. Ka for HBr is equal to 8.7 x 10^-10 at 25°C.Using these values, we can calculate the concentration of H3O+ ions in the solution.

The acidity or alkalinity of a solution depends upon its hydronium ion concentration and hydroxide ion concentration. The concentration of OH⁻ is 1 × 10⁻⁴ M.

The pOH expresses the hydroxide ion concentration of a solution. The pOH of a solution is defined as the negative logarithm to the base 10 of the value of the hydroxide ion concentration in moles per litre.

The equation used to calculate the concentration of OH⁻ is:

pOH = -log [OH⁻]

[OH⁻] = 10⁻pOH

[OH⁻] = 10⁻⁴

= 0.0001 M

The number of significant figures in a reported value is the number of digits that are known with certainty plus the last one having some uncertainty.

Here 0.0001 contains 3 significant figures. In scientific notation it can be represented as 1 × 10⁻⁴ M.

Thus the concentration of [OH⁻] is 1 × 10⁻⁴ M.

The energy needed to remove an electron from an atom is called the ionization energy.

Ionization energy refers to the amount of energy required to overcome the electrostatic attraction between the positively charged nucleus and the negatively charged electron, resulting in the removal of the electron from the atom.

When an electron is tightly bound to an atom, it requires a certain level of energy to break free from its orbit and become a free electron. This energy is specific to each atom and is influenced by factors such as the atomic number, electron configuration, and shielding effect of inner electrons. The ionization energy is commonly measured in units of electron volts (eV) or kilojoules per mole (kJ/mol).

Ionization energy plays a crucial role in various fields of science, including chemistry, physics, and materials science. It is particularly important in understanding chemical bonding, reactivity, and the behavior of atoms and ions. Elements with low ionization energies tend to readily lose electrons and form positive ions, while elements with high ionization energies are more likely to gain electrons and form negative ions.

Ionization energy is the energy required to remove an electron from an atom, and it has significant implications for the understanding of atomic structure, chemical reactions, and the properties of elements.

The electron-pushing mechanism for the decarboxylation reaction involves the addition of three curved arrows. The reaction starts with a carboxylic acid, which undergoes a proton transfer to form a carboxylate anion. The carboxylate anion then experiences nucleophilic attack by a base, leading to the formation of a cyclic intermediate. The cyclic intermediate undergoes ring opening, resulting in the expulsion of carbon dioxide and the formation of a new bond. The electron-pushing mechanism helps illustrate the movement of electrons throughout the reaction, highlighting the formation and breaking of bonds.

In the decarboxylation reaction, we start with a carboxylic acid, which is represented by the structure: C(O)OH. The first step involves the proton transfer, where a curved arrow is drawn from one of the lone pairs on the oxygen of the carboxylic acid to the hydrogen atom attached to the same oxygen. This proton transfer leads to the formation of a carboxylate anion, depicted as C(O)O-.

The second step involves nucleophilic attack by a base. Draw a curved arrow from the lone pair on the oxygen of the carboxylate anion to the carbon atom adjacent to the carbonyl group. This movement of electrons results in the formation of a cyclic intermediate. The cyclic intermediate is represented by a ring structure formed by the interaction between the carbon atom and the oxygen atom of the carboxylate group.

The third step involves ring opening. Draw a curved arrow from the carbon atom of the cyclic intermediate to the oxygen atom of the carboxylate group. This movement of electrons breaks the bond between the carbon atom and the oxygen atom, resulting in the expulsion of carbon dioxide (CO2). Simultaneously, a new bond is formed between the carbon atom and the neighboring atom (not specified in the given question).

The overall reaction can be summarized as the decarboxylation of a carboxylic acid, leading to the removal of a carbon dioxide molecule and the formation of a new bond. The electron-pushing mechanism helps visualize the flow of electrons during the reaction, highlighting the formation and breaking of bonds at each step.

Answer:

Explanation:

In the ionic compound CrCl3, the subscript "3" indicates that there are three chloride ions (Cl-) for every chromium ion (Cr3+).

To determine the charge on the chromium ion, we need to consider the charges of the chloride ions and the overall charge neutrality of the compound.

The chloride ion (Cl-) carries a charge of -1. Since there are three chloride ions in CrCl3, their total charge is -3 (-1 x 3 = -3).

For the compound to be electrically neutral, the total positive charge of the chromium ion must balance the total negative charge of the chloride ions. Therefore, the charge on the chromium ion (Cr3+) must be +3 to counterbalance the -3 charge from the chloride ions.

So, the charge on the chromium ion in CrCl3 is +3.

23.0 s⁻¹ is rate constant

Explanation:

Using the Arrhenius equation:

k = A * e^(-Ea/RT)

Where k is rate constant

A is frequency factor (1.5x10¹¹s⁻¹)

Ea is activation energy = 55800J/mol

R is gas constant (8.314J/molK)

And T is absolute temperature (24°C + 273 = 297K)

Replacing:

k = 1.5x10¹¹s⁻¹ * e^(-55800J/mol/8.314J/molK*297K)

k = 1.5x10¹¹s⁻¹ * 1.53x10⁻¹⁰

Akera's sample is not random because he is only surveying every fifth tennis player, which introduces bias into the sample.

Akera's sample is not random. The sampling method he employed, which is surveying every fifth tennis player entering the court, is a form of systematic sampling. In systematic sampling, the researcher selects every nth individual from a population to create the sample.

While systematic sampling can be a useful sampling technique in certain cases, it is not considered random because it introduces a systematic pattern into the selection process. This pattern could potentially introduce bias into the sample by excluding certain types of tennis players or favoring others.

For example, if there is a pattern or clustering in the characteristics or behaviors of tennis players as they enter the court, Akera's sampling method may systematically over or underrepresent certain groups of players. If, for instance, there is a tendency for more experienced players to arrive early and less experienced players to arrive later, Akera's sample may not be representative of the entire population of tennis players at the athletic center.

To achieve a random sample, Akera would need to use a different sampling method, such as simple random sampling, where each member of the population has an equal chance of being selected. This would help ensure that the sample is more representative and reduces the potential for bias in the research findings.
