What is the amount of energy stored in a molecule?
The amount of energy stored in a molecule depends on its chemical bonds and structure. This energy is typically measured in units like kilojoules per mole or electron volts. The energy stored in a molecule is released or absorbed during chemical reactions.
An oxygen molecule O2 has twice the mass of a methane CH4 molecule In a planet's atmosphere at some particular temperature the average kinetic energy of an oxygen molecule is?
The kinetic energy of a gas molecule is directly proportional to its temperature, as per the kinetic theory of gases. Therefore, if the temperature is the same for both oxygen and methane molecules in the planet's atmosphere, then the average kinetic energy of an oxygen molecule is the same as that of a methane molecule. The mass of the molecule does not impact its kinetic energy at a given temperature.
What are the units for standard Gibbs free energy?
The units for standard Gibbs free energy are joules per mole (J/mol) or kilojoules per mole (kJ/mol).
How does the energy value of a carbohydrate molecule compare to the energy of a fat molecule?
Fats provide more than twice the energy.Carbohydrates (including sugars) provide about 4 dietary calories (kilocalories) per gram.Fats provide about 9 dietary calories (kilocalories) per gram.Proteins provide about 4 dietary calories (kilocalories) per gram.Common foods are not entirely composed of these molecules, containing considerable water weight and fiber (no calorie value).
What is the stabilization energy of naphthalene?
The stabilization energy of naphthalene is due to resonance effects in its aromatic system. This energy arises from the delocalization of pi-electrons throughout the molecule, resulting in increased stability compared to non-aromatic compounds. It helps to lower the overall energy of the molecule and contributes to its unique properties.
Is the temperature of an object a measure of the total kinetic energy of molecules in the object of a measure of the average kinetic energy per molecule in the object?
Temperature is a measure of the average kinetic energy per molecule in an object. It is not a measure of the total kinetic energy of all the molecules in the object.
Is the average kinetic energy per molecule the same for oxygen and nitrogen molecules in air at a given temperature?
Yes, at a given temperature, the average kinetic energy per molecule is the same for oxygen and nitrogen molecules in air. This is because the kinetic energy of a gas molecule is determined by its temperature, and not its composition.
What is the amount of energy stored in a molecule?
The amount of energy stored in a molecule depends on its chemical bonds and structure. This energy is typically measured in units like kilojoules per mole or electron volts. The energy stored in a molecule is released or absorbed during chemical reactions.
What is the average kinetic energy per molecule of the gas?
(3/2)kT
Is the temperature of an object a measure of the total translational kinetic energy of molecules in the object or a measure of the average translational kinetic energy per molecule in the object?
Temperature is a measure of the average translational kinetic energy per molecule in an object. It represents the average energy of motion of individual molecules within the object.
Calculate the energy yield of aerobic cellular respiration per glucose molecule?
38
Which group of bio-molecules is the most efficient for storing energy?
Lipids, specifically triglycerides (fats), are the most efficient biomolecules for storing energy in living organisms. They contain more than twice as much energy per gram as carbohydrates or proteins, making them a highly efficient energy storage molecule.

The kinetic energy of a gas molecule is directly proportional to its temperature, as per the kinetic theory of gases.

What type of molecule in the yolk of a chicken egg provides the most energy for a developing a chick?
The type of molecule in the yolk of a chicken egg that provides the most energy for a developing chick is fat, specifically in the form of triglycerides. These fats are energy-dense, offering more calories per gram than carbohydrates or proteins, making them a crucial energy source during the chick's development. Additionally, the yolk contains proteins and other nutrients, but fats are the primary energy reserve.
Does Anaerobic cellular respiration produces the most energy?
No, aerobic cellular respiration produces more energy than anaerobic respiration. Anaerobic respiration (like fermentation) produces just 2 ATP molecules per glucose molecule, while aerobic respiration produces up to 36-38 ATP molecules per glucose molecule.
