A map is an example of a A observation B inference C prediction D model?
A. Observation Observation is the use of the senses to gather and record information about structures or processes in nature. (:
How is the bond between hydrogen atoms represented in each model of a hydrogen molecule?
well it is because the hydrogen molecule = the velocity of molecules in hydrogen which gives you the answer to your question.
What is the structure of NO2?
This ionic compound exists of two ions:ammonium, NH4+, is tetraedric (with H at 4 corners and N+ in centre)nitrate, NO3-, is trianular flat with N centred and O(1/3)- at 3 corners)The cristallic structure made of these ions (1 to 1) is trigonal. Nice pictures are at wikipedia, link is to be found at 'Related links' next to this answer, just clicking.[Ball-stick model, red = N, white = H, blue = N)
What term is used to describe a representation of a thing or system?
it is called a model
Bohr model for sulfur?
what is a Bohr model for sulfur?
What is a Lewis Structure?
A Lewis structure is a model that uses electron-dot structures to show how electrons are arranged in molecules. Pairs of dots or lines represent bonding pairs this is a CO32− model
What is a small scale structures called?
A model.
What was the name of atomic model?
'Atomistic' model, (since molecules where not recognised at that time)
What are the model of molecules of matter?
compound, element and mixture
What is collision model?
A Collision model is a model of the rate of a reaction showing how the rate is proportional to the number of collisions of reactant molecules.
What is maxwell-boltzman distribution?
a simple model that describe the distribution of velocity of molecules in a gas with probabality concept. according to this model the probability of finding a certain velocity in a gas is proportional to e-E/KT, where E=1/2 mv2 for a free atoms of a gas.
What is the name of the model developed by scientists to describe the arrangement of molecules within this structure?
Fluid mosaic model.
Have molecules in a place in a fixed position?
If you use classical model to describe gas molecules you will get the result: molecules of gas always move unless temperature of the gas is zero.
The movement of protein molecules within the phospholipids bilayer is described by the?
fluid mosaic model
Which part of the spring model how molecules of air are close together?
taco
How could you change a DNA model to show changes in DNA molecules?
h
In the conservative model for replication of DNA progeny DNA molecules consist of?
