This difference occurs because they charge electrons at different points in the electron transport chain.
NADH pairs electrons with the first enzyme complex, the NADH dehydrogenase complex, and FADH₂ shares electrons with the second enzyme complex, the succinate dehydrogenase complex. This modifies the number of protons pumped out of the mitochondria per molecule of NADH and FADH₂ and determines the amount of ATP produced.
NADH is the reduced form of nicotinamide adenine dinucleotide (NAD), while FADH₂ is the reduced form of flavin adenine dinucleotide (FAD). NADH is a coenzyme derived from vitamin B3 (niacin) and FADH₂ is a coenzyme derived from vitamin B2 (riboflavin)

what is the theoretical yield of iron (55.845 g/mol) when 10.0 g fe2o3 (159.69 g/mol) reacts with excess carbon (12.01 g/mol)?
The theoretical yield of iron (55.845 g/mol) when 10.0 g Fe₂O₃ (159.69 g/mol) reacts with excess carbon (12.01 g/mol) is 6.99 g.
the balance equation is given as :
Fe₂O₃ + 3C ----> 2Fe + 3CO
the mass of Fe₂O₃ = 10 g
molar mass of Fe₂O₃ = 159.69 g / mol
the number of moles of Fe₂O₃ = mass / molar mass
= 10 / 159.69
= 0.062 mol
1 mole of Fe₂O₃ produce 2 mole of Fe
0.062 mol of Fe₂O₃ = 2 × 0.062 = 0.125 mol of Fe
mole of Fe = 0.125 mol
molar mass of Fe = 55.8 g/mol
mass of Fe = 0.125 × 55.5
= 6.99 g
The theoretical yield = 6.99 g
Thus, The theoretical yield of iron (55.845 g/mol) when 10.0 g Fe₂O₃ (159.69 g/mol) reacts with excess carbon (12.01 g/mol) is 6.99 g.

if you wished to dissolve 10g of sucrose sugar in 1l of h2o, which actions would be helpful? heat stirring heat and stirring neither heat nor stirring
Stirring is only required to dissolve sucrose sugar in water.
What is solubility?
Solubility in chemistry refers to a chemical's capacity to dissolve in another substance, the solvent, to produce a solution. The opposite characteristic, insolubility, refers to the solute's incapacity to create a solution. The solvent is often a solid or a liquid, whereas the solute may be a solid, liquid, or gas. Both could be solution-based compounds or pure chemicals. Except in extremely rare circumstances, gases are always miscible in all ratios, and the only way a solid or liquid may be "dissolved" in a gas is by first becoming gaseous.
Temperature, pressure, and the makeup of the solute and solvent (including their pH and the presence of additional dissolved materials) are the key determinants of solubility.
Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules. The weak bonds that form between the solute and the solvent compensate for the energy needed to disrupt the structure of both the pure solute and the solvent.Hence, stirring is only required to dissolve sucrose sugar in water.

Explain how the bonding model for sodium metal would differ from the bonding model for nacl.
Answer:
Explanation:
The bonding in NaCl involves a sodium ion and a chloride ion while the bonding in sodium metal involves sodium ions and a sea of electrons.
NaCl involves sodium and ion and chloride ion held together by an ionic bond. The sodium atom transfers an electron to chlorine atom to yield the chloride ion. This ion pair exists in the compound called sodium chloride.
In sodium metal, the sodium cations interact electrostatically with a sea of electrons in a metallic bond. Hence, while the bonding in sodium chloride involves an ion pair, the bonding in sodium metal involves sodium ions and a sea of electrons.
which of the elements above do you predict will have the highest boiling point? a) fluorine b) chlorine c) bromine d) iodine
Florine (f) has the highest boiling point of the halogen elements
Boiling pointThe boiling point of a compound is influenced by several factors including Mr and intermolecular bonds. The greater the Mr and the intermolecular bonds. The bigger the Mr, the higher the boiling point. For acid halides, the order of boiling points from highest to lowest is:
HF>HI>HBr>HCl
In HF compounds the influence of intermolecular bonds is very strong.
The trend of the melting and boiling points of the halogens can be explained as follows.
The halogen molecule (X2) is nonpolar, thus the attraction between halogen molecules is a dispersion force. As is known, the dispersion force increases in accordance with the increase in molecular mass (Mr).

true or false: in order to balance the reaction of hydrogen gas (h2) with oxygen gas (o2) to form liquid h2o, a student adds a subscript of 2 to h2o (forming h2o2). this is an acceptable method of balancing the reaction described.
A group of students perform an experiment to determine the value of the gas constant. They
forgot to include the vapor pressure of water in their calculations. Will the value of the
experimentally determined gas constant be high, low, or unaffected?
The value of the gas constant will be high due to the increase in gas pressure.
Solution:
According to Ideal Gas Law, PV=nRT
where, P = Gas pressure (in atmospheres), V= Gas Volume (in Liters), n = number of moles of gas sample T= Gas Temperature (in Kelvins), R = Gas Constant.
[tex]\therefore R=\frac{(P\ast V)}{(n\ast T)}[/tex] ....... (1)
P = [tex]P_{atm}[/tex] - [tex]P_{water vapor}[/tex]
where = Atmospheric pressure[tex]P_{water vapor}[/tex] = Partial pressure of water vapor.
If students forgot to include the vapor pressure of water in the calculation of gas constant then the magnitude of pressure due to gas(P) will be more because they are not substracting the Water vapor value from the [tex]P_{atm}[/tex]to get the actual P value.
The value of the gas constant will be high due to the increase in gas pressure.
The ideal gas constant R can be found experimentally by determining the number of moles of gas occupying a given volume of measurement at a known pressure and temperature.

35g
Explanation:Noting the mass of scientific tools such as beakers can help us take the mass of liquids and other samples that cannot be measured on their own.
Mass of the Liquid
To find the mass of the liquid, we have to know the mass of the beaker. Then, we can subtract the mass of the beaker from the mass of the liquid and beaker combined. This will leave the mass of the liquid.
135 - 100 = 35The liquid has a mass of 35g.
Significant Figures and Units
Whenever doing scientific calculations, it is important to include significant figures and units.
Significant figures show the accuracy of a measurement. When, subtracting numbers, round to the smallest number of decimal places. Neither measurement has decimal points, thus the answer also should not have a decimal point. Thus the answer is just 35.

where within the saturated zone do you suppose the concentration of carbonic acid is greater- shallow or deep?
The concentration of hydrogen ions increases as a result of a series of chemical reactions that take place when CO2 is absorbed by saltwater.
The seawater's acidity rises as a result, and carbonate ions become relatively less common. Seawater absorbs carbon dioxide, which is present naturally in the atmosphere. Carbonic acid (H2CO3) is created when water and carbon dioxide mix. This weak acid dissociates into hydrogen ions (H+) and bicarbonate ions (HCO3-). Carbonate from the sea is used by marine life to create their shells and skeletons. Carbonate is less readily available for animals to build their shells and skeletons as seawater becomes more acidic. Shells and skeletons may dissolve in highly acidic environments.

How do acid and bae interact with water? how doe thi interaction be different for trong acid and weak acid?
Acids give hydrogen ions (H+) to water when they are dissolved in it. The hydrogen atoms that make up hydrogen ions have just one proton left after losing an electron, giving them a positive electrical charge.
What transpires to strong bases and acids in water?Acids and bases dissolve in water and inhibit water dissociation by increasing the concentration of either protons or hydroxide ions, one of the byproducts of water self-ionization.
In an aqueous solution, strong acids and bases are completely ionised. In an aqueous solution, weak acids and bases ionise to a lesser extent. The acidity or basicity of their aqueous solutions can be changed by the salts of weak acids or bases.
Water has the capacity to combine to function as both an acid and a base simultaneously.
