What is the diameter of hydrogen molecules?
The diameter of a hydrogen molecule is approximately 120 picometers (pm), which is equivalent to 0.12 nanometers (nm).
What is the diameter of an ammonia molecule?
Ammonia molecule is not spherical but triangular pyramidal in shape. Hence it is not possible to tell its shape.
What is the size of a urea molecule in angstroms?
The size of a urea molecule is approximately 2-3 angstroms in diameter.
Why is colorimetric estimation of copper done at 620 nm?
Copper can form a colored complex with a reagent (such as neocuproine) that absorbs light at 620 nm. By measuring the absorbance of this complex at 620 nm, the concentration of copper in a solution can be calculated based on Beer-Lambert's law.
Which substance present in the atmosphere is responsible for the absorption of solar radiation with a wavelength less than 242 nm?
Oxygen is responsible for the absorption of solar radiation with a wavelength less than 242nm. UV radiation splits oxygen into atoms and the atoms combine with other oxygen molecules to form ozone. Generally, all multi-atom?æ compounds are capable of absorbing UV radiation when the wavelength is short.
What is difference between micropores and mesopores?
A macropore has a diameter of more than 50 nm , a mesopore has a diameter of 2 nm - 50 nm, a micropore has a diameter of less than 2 nm, a nanopore has a diameter of approximately 1 nm. Nm means nanometer.
What is the diameter of hemoglobin?
The diameter of Hb molecule is app. 5.5 nm, and that is larger than a glucose molecule.
What is the diameter of nucleus of hydrogen in nm?
1,75.10-6 nm
Are ribosomes small or large?
70s in a Prokaryotic cell and 80s in an Eurakaryotic cell.
How large is a rhinovirus?
The spherical virus particles have a diameter of 50 to 70 nm and are covered by a lipid membrane. There are prominent "spikes" of 6 nm. Inside the lipid envelope is a capsid of 40 nm in diameter.
Does a colloid contain particles that are between 1 nm and 1000 nm in diameter?
Yes.Yes.Yes.Yes.
Is suspension colloid solution or compound smaller?
Suspension is typically made up of larger particles (greater than 1000 nm) that are dispersed in a liquid. In contrast, a colloid solution consists of particles that are intermediate in size between a suspension and a true solution (1-1000 nm). Therefore, the particles in a suspension are generally larger than those in a colloid solution.
What is the molecular diameter of benzene?
The molecular diameter of benzene is approximately 0.68 nanometers.
How does the large intestines differ from the small intestine in diameter?
The large intestine's diameter is about 3,000 nm larger than the diameter of the small intestine, that is if you are comparing the lengths and widths of the two at a 2:1 ratio, then yes. But if you are measuring the 3-Dimensional Analysis from an objective point of view then at a 5:4 ratio it would be 400,000 nm in size precisely.
How does the large intestine differ from the small intestine in term diameter?
The large intestine's diameter is about 3,000 nm larger than the diameter of the small intestine, that is if you are comparing the lengths and widths of the two at a 2:1 ratio, then yes. But if you are measuring the 3-Dimensional Analysis from an objective point of view then at a 5:4 ratio it would be 400,000 nm in size precisely.
What is the wavelenght of uv rays?
Less than that of visible light, which is in the range of about 350-700 nm - so UV rays would have a wavelength below 350 nm.
How big does a virus get?
Viruses generally range from 20 nanometres to 300 nm in diameter although the largest can be as much as 500 nm. Their lengths range from 700 to 1000 nm.
