Bond length in a an Br2 molecule?
The bromine diatomic molecule has a bond energy of 190 kilojoules per mole. This translates to a bond length of 228 picometers.
Why do oxygen molecules move slowly than hydrogen molecules at the same temperature?
Two gasses at the same temperature have the same amount of average kinetic energy per molecule. Since an oxygen molecule has about 16 times the mass of a hydrogen molecule, it must move faster than a hydrogen molecule with the same kinetic energy. This is based on the equation KE=1/2MV2
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).
Why does a higher concentration make a reaction go faster?
When the concentration of a solution increases, the particles are moving quicker as they have more energy. This results in more collisions between the substrate and the solution, thus resulting in an increased rate of reaction. Even if the particles are moving at the same speed, with a higher concentration, there is a higher probability of colliding with another reactant molecule rather than a solvent molecule.
Does methane have a higher density than oxygen and carbon dioxide?
Oxygen gas (2 Oxygen atoms per molecule) has a molecular weight of 32 g per mol, Carbon dioxide (1 Carbon atom + 2 Oxygen atoms per molecule) has a molecular weight of 44 g per mol, Methane (1 Carbon atom + 4 Hydrogen atoms per molecule) has a molecular weight of 16 g per mol, which that means when under the same temperature and pressure conditions, with the same amount of particles in the space (volume), methane would be the least dense of these gases, followed by oxygen, then finally carbon dioxide the most dense.
What is the average kinetic energy per molecule of the gas?
(3/2)kT
Calculate the energy yield of aerobic cellular respiration per glucose molecule?
38
Is the average kinetic energy per molecule the same for oxygen and nitrogen molecules in air at a given temperature?
Oxygen and nitrogen have equal average kinetic energy per molecule at room temperature. This is assuming that both oxygen and nitrogen molecules are in fact at room temperature.
What is the relationship between temperature and molecular and kinetic energy?
The definition of temperature is the average kinetic energy of a molecule/solid/whatever
During the energy investment phase of glycolysis, how many ATP are required to continue with the reactions per glucose molecule?
Two
What wavelength of electromagnetic carries the most energy?
Gamma rays have the most energy per photon.

Why is Octanol an energy efficient fuel?
"Octanol is not the most energy efficient fuel. Butanol is. Octanol gives out 8691.34J of energy per gram. Butanol gives out 15521.21J of energy per gram" Please state your source.
What wavelength of electromagnetic radiation carries the most energy?
Gamma rays have the most energy per photon.
