How do you distinguish between a macro-molecular from molecular?
A macromolecule is formed from many molecules linked together in a chain and of course has a higher molecular mass.
Two diatomic molecules with an equal number of electrons and a similar molecular weight are tested for boiling point the difference in boiling point is 150 degrees which is most likely?
the polar molecule has a higher boiling point
What does the word diffusion mean?
it is the transport of molecules from a region of higher concentration to one of lower concentration by random molecular motion.
Does the molecules in a solid have motion or energy?
As temperature of a solid is increased, molecular motion increases.Since, temperature of a solid is directly proportional to average vibrational kinetic energy of molecules of a solid, therefore, energy of a solid increases with an increase in temperature. So, it demonstrates that molecular motion is directly proportional to energy i.e. the higher the energy of solid, the higher is the molecular motion.
What is diffusing in science?
Diffusion is a net transport of molecules from a region of higher concentration to one of lower concentration by random molecular motion.
Does changing the temperature affect the rate of osmosis?
Certainly; molecules move faster at a higher temperature (that is what temperature is, at a molecular level) and therefore undergo osmosis faster as well, since that is a form of molecular motion.
What happens in the process of diffusion?
During diffusion molecules move from a region of higher concentration to one of lower concentration by random molecular motion.
During the process of diffusion what happens?
Diffusion is the movement of molecules from a region of higher concentration to one of lower concentration by random molecular motion.
Is propanoic anhydride or butanoic anhydride having a higher boiling point?
All else being equal/similar, the higer the molecular weight, the higher the boiling point.
What do you call the movement of molecules or atoms from a region of higher concentration to a region of lower concentration?
The Atomic or Molecular movements generally known as Osmotic diffusion.
What causes has pressure?
The answer depends on what kind of pressure. If you mean the pressure exerted by gasses on the walls of a container (a balloon, for example), pressure is created by the motion of the molecules of gas. Temperature and density of the molecules are factors. Higher density results in higher pressure. Higher temperature creates more molecular motion, thereby creating higher pressure.
Why is the boiling point of water higher than an organic compound with the same molecular weight?
Water molecules are strongly intermolecularily bonded by (polar) hydrogen bonding.
