What thing cannot be viewed in compound microscope?
Viruses. They are smaller than the average wavelength of light and as such are not viewable unless an electron microscope is used.
Which of these observations led to the law of triads?
The average of two atomic weights for a group of three elements equaled the atomic weight of the third.
WHAT IS THE AVERAGE DIAMETER of A copper atom?
hey ive found this site. it helped me a lot. the diameter of copper is 2.551 x 10^-10 m http://www.copper.org/resources/properties/atomic/homepage.html
What are the elements produced by a fission reaction?
1. Fission products (lighter elements) 2. Energy from the loss of mass, appears initially as kinetic energy which is absorbed in the fuel bulk and transformed to thermal energy (heat) 3. Free neutrons-average 2.5 per fission 4. Gamma radiation
What are the limitations of coulomb's law?
coulombs law is valid if the average number of solvent molecules between two interacting charges is large enough that the properties of the micro region of solvent can be expected to b similar to that of the bulk solvent.
By what property did Mendeleev suggest that the periodic table be arranged?
Madeleev originally arranged the elements in the first periodic table by their average atomic masses. Later it was changed to atomic number by Moseley, or the number of protons each of that element's atom has.
What is the average sum of the elements divided by number of elements?
the sum of the elements divided by the number of elements is the average
How do carbon liquids change to a gas?
since it is carbon, the properties are different from the average compound. therefore, freeze it instead of heating it to change it to a gas. sorry my shift key isn't working
What is the resemblance between newland classification element and music?

Is average a compound word?
no
What is the limitation of dobereiners periodic table?
All the elements known at that time could not be arranged as Dobereiner's triad's example: the three elements, nitrogen, phosphorus and arsenic have similar properties. Therefore they can be regarded to form a triad. However, the actual atomic mass if the middle element, phosphorus(P)(31.0u)is much lower than the average or mean(44.45u)of the atomic masses of nitrogen and arsenic. Thus, these three elements do not constitute a Dobereiner triad in spite of their similar chemical properties.
The average the sum of the elements divided by the number of elements?
Yes, average is the sum of elements divided by the number of elements Exp:- x1=10, x2=20, x3=30, x4=10. then the average is 10+20+30+10 ------------------ 4 => 17.5 Average = sum of total of element ---------------------------------- no. of elements
What is the average cost of real estate properties in Costa Rica with 3 bedrooms?
The average cost of real estate properties in Costa Rica about 249,000 to 350,000. This is for a three bedroom home. The prices are higher as the properties get closer to the beach.
Are the properties of compounds something like an average of the properties of its compnent elements?
false. once they r combined, they are inseparable and one totally different thing
Who created the triads and what was it?
Johann Dobereiner - noticed that the atomic weight of strontium fell midway between the weights of calcium and barium, elements possessing similar chemical properties. In 1829, after discovering the halogen triad (composed of chlorine, bromine, and iodine) and the alkali metal triad of (lithium, sodium and potassium) ***he proposed that nature contained triads of elements the middle element had properties that were an average of the other two members when ordered by the atomic weight (the Law of Triads)
Partial molar property and its applications?
Partial molar properties are useful thermodynamic properties because their molar average equals the property itself. In this article, we present a description of partial properties in general, and we show that for many partial properties, partial molar properties being a subset, the property is a molar average of the partial properties. Although partial molar properties remain the most useful, several of the other partial properties could have practical applications. © 2009 American Institute of Chemical Engineers AIChE J, 2009
What scientist published the first periodic table and how was it arranged?
In 1817, Döbereiner began to formulate one of the earliest attempts to classify the elements. He found that some elements formed groups of three with related properties. He termed these groups "triads". In all of the triads, the atomic weight of the second element was almost exactly the average of the atomic weights of the first and third element..
