Joe has a disease that his cells can't convert food energy effectively into energy they can use. He gets extremely tired as a result. Which organelle is affected by Joe's disease?

Answer:

2.38 mol of Al

Explanation:

To find the number of moles in a substance, you simply divide by the atomic mass. In this case, the conversion table would look as follows:

\(\frac{64.1 g}{1}\) * \(\frac{1 mol}{26.98 g}\)

The gram units cancel, and you are left with the answer of about 2.38 moles of Aluminum.

Answer:

2 atoms

Explanation:

There are 2 atoms in element NaCl. This is because there is 1 atom of Na (sodium) and 1 atom of Cl (chlorine) in each NaCl molecule. Elements by themselves do not have a "number of atoms"- if you're talking about the atomic number, it's the number of protons (or electrons in a neutral atom) of an element.

The condensation reaction between two molecules of glucose would result in the formation of maltose (C12H22O11) and the release of water.

Carbohydrates are organic compounds that are used to store energy. An example of a carbohydrate is glucose, which is a single sugar or a monosaccharide. The process of forming larger molecules from the combination of simple sugars is called the condensation process. A water molecule is released in the process of combining the molecules together through a glycosidic bond.

The condensation reaction for two molecules of glucose (C6H12O6) results in the formation of maltose, a disaccharide, and the release of water. The molecular formula of maltose is C12H22O11. It can be observed that the condensation reaction shown below is balanced.

Glucose (C6H12O6) + Glucose (C6H12O6)  → Maltose (C12H22O11) +H2O

Answer:

Nonpolar molecules dissolve in nonpolar solvents through a process called dispersion forces or London forces.

In nonpolar molecules, the electrons are evenly distributed and there is no permanent dipole moment, which means that the molecule has no positive or negative poles. When nonpolar molecules are added to a nonpolar solvent, such as oil or hexane, the molecules are attracted to one another due to London dispersion forces.

London forces are due to temporary fluctuations in electron density within molecules, creating temporary dipoles. These temporary dipoles induce corresponding temporary dipoles in other nearby molecules, attracting them to each other. The strength of the London dispersion forces increases with the size of the molecule, since larger molecules have more electrons and a greater potential for temporary dipoles.

In general, nonpolar molecules bind together in nonpolar solvents through these weak intermolecular forces, allowing them to dissolve and form a homogeneous solution.

Entropy usually increases when a solution forms because there are more interactions between particles in a solution.

The particles in a solution generally have greater freedom of movement than the particles in a pure solute.

When a solution is formed, the interactions between particles increase, leading to an increase in entropy. In a solution, solute particles interact with solvent particles, resulting in more degrees of freedom for the particles. This increased freedom of movement contributes to higher entropy compared to the particles in a pure solute.

The first statement is correct because the increased number of interactions between particles in a solution leads to more possible arrangements, resulting in higher entropy.

The second statement is also correct because, in a solution, solute particles are dispersed and surrounded by solvent molecules, allowing them greater freedom of movement compared to being in a pure solute state.

Overall, both statements correctly describe the change in entropy when a solution is formed: entropy usually increases due to increased interactions between particles and greater freedom of movement for the particles in the solution.

The coefficients needed to balance the redox reaction are: 2Fe(s) + 3Cl2(g) + 6H+(aq) -> 2Fe3+(aq) + 6Cl-(aq) + 3H2O(l)

The balanced redox reaction requires two molecules of chlorine gas to react with one atom of iron, producing one Fe3+ ion and two chloride ions. We need to balance both the mass and charge on each side of the equation.

Step 1: Balance the atoms other than oxygen and hydrogen.

Fe(s) + Cl2(g) -> Fe3+(aq) + 2Cl-(aq)

Step 2: Balance the oxygen atoms by adding water (H2O) molecules.

Fe(s) + Cl2(g) -> Fe3+(aq) + 2Cl-(aq) + H2O(l)

Step 3: Balance the hydrogen atoms by adding hydrogen ions (H+).

Fe(s) + Cl2(g) + 6H+(aq) -> Fe3+(aq) + 2Cl-(aq) + H2O(l)

Step 4: Balance the charges by adding electrons (e-).

Fe(s) + Cl2(g) + 6H+(aq) -> Fe3+(aq) + 2Cl-(aq) + H2O(l) + 6e-

The balanced equation for the redox reaction is:

2Fe(s) + 3Cl2(g) + 6H+(aq) -> 2Fe3+(aq) + 6Cl-(aq) + 3H2O(l)

The balanced redox reaction is 2 Fe(s) + 3 Cl2(g) -> 2 Fe3+(aq) + 6 Cl-(aq) with coefficients 2, 3, 2, and 6 respectively.

Carnot's work attracted little attention during his lifetime, but it was later used by Rudolf Clausius and Lord Kelvin to formalize the second law of thermodynamics and define the concept of entropy.

Sadi Carnot was a French physicist who is known for his studies on the efficiency of heat engines. In 1824, he published a book called "Reflections on the Motive Power of Fire," in which he laid out the principles of thermodynamics and introduced the concept of entropy. His work was crucial in the development of the steam engine, as it helped engineers to understand how to make engines more efficient. Carnot's studies on steam engine efficiency laid the groundwork for the development of the concept of entropy, which is a measure of the disorder or randomness of a system. (C)

Answer:

bile salts emulsify fats and break them down into smaller particles which gives the enzyme lipase a greater surface area to act on during digestion of fats.

Explanation:

The voltage across the 200 ohm circuit element, that draws a current of 4 A, is equal to 800 volts.

To find the voltage across a circuit element, take Ohm's Law, according to which the resistance (R) of a resistor is equal to the product of the current (I) that flows through it and the voltage (V) across it.

Use the values:

Current (I) = 4 A

Resistance (R) = 200 Ω

Using the formula of Ohm's Law:

V = I × R

V = 4 A × 200 Ω

V = 800 V

Voltage is  800 V.

Thus, the voltage across the 200 ohm circuit element, that draws a current of 4 A, is 800 volts.

Water has the highest polarity due to its strong hydrogen bonding and is considered a polar solvent. Ethanol and acetone have intermediate polarity and are also considered polar solvents.

On the other hand, hexane and toluene have low polarity and are considered nonpolar solvents. Ethyl acetate has moderate polarity, similar to that of ethanol and acetone, and is also considered a polar solvent. Understanding the polarity of solvents is important in many laboratory procedures, such as chromatography, extraction, and purification. Polar solvents are used to dissolve polar compounds, while nonpolar solvents are used to dissolve nonpolar compounds.

Here's a ranking of the solvents you listed based on their polarity:

1. Water - High polarity
2. Ethanol - High polarity
3. Acetone - High polarity
4. Ethyl acetate - Intermediate polarity
5. Toluene - Low polarity
6. Hexane - Low polarity

Water, ethanol, and acetone are highly polar solvents due to their ability to form hydrogen bonds. Ethyl acetate has intermediate polarity because it has polar functional groups but lacks hydrogen bonding. Toluene and hexane are nonpolar solvents with low polarity, as they mainly consist of carbon-hydrogen bonds.

The rate of effusion of a gas is inversely proportional to its molar mass.

Therefore, the gas with the molar mass closest to that of nitrogen (14 g/mol) will have the most similar rate of effusion to nitrogen at 350 K.

The gas with the molar mass closest to that of nitrogen is hydrogen (1 g/mol). Therefore, the gas with the most similar rate of effusion to nitrogen at 350 K is hydrogen (H2). The other gases (CH4, CO, CO2, and Ne)

all have molar masses significantly higher than nitrogen, and therefore they will have slower rates of effusion than nitrogen at 350 K.
