Which of these observations led to the law of triads?
The observation that groups of three elements had similar properties and atomic weights led to the development of the law of triads by Johann Dobereiner in early 19th century chemistry. This law suggested that elements could be grouped into sets of three with similar characteristics where the atomic weight of the middle element was roughly the average of the other two.
Temperature and heat are different but related blank properties?
Temperature and heat are different but related intensive properties. Temperature is a measure of the average kinetic energy of particles, while heat is the transfer of energy between systems due to a temperature difference.
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.
How much does oil expand when heated?
On average, oil expands by about 0.07% for every 10 degrees Fahrenheit increase in temperature. This expansion is due to the thermal expansion properties of oil.
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
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
Johann Dobereiner placed elements with similar properties in to groups of threes called what?
Johann Dobereiner grouped elements with similar properties into triads. In these triads, he observed that the properties of the middle element were the average of the other two.
How would the modern periodic table would be different if elements were arranged by average atomic mass instead of by atomic number?
how would the modern Periodic Table be different if elements were arranged by average Atomic Mass instead of by atomic number
How many elements were discovered when dobernier gave his triad?
When Johann Wolfgang Döbereiner proposed his triads in the early 19th century, he identified three groups of three elements, totaling nine elements. These triads were based on the observation that the properties of the middle element in each triad were often an average of the properties of the other two. Döbereiner's work was significant in the development of the periodic table, highlighting periodicity in elemental properties.
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 did mendeleev first worked out this order of elements?
Dmitri Mendeleev arranged the elements by increasing atomic mass and similar chemical properties. He left gaps for undiscovered elements and predicted their properties based on the pattern he observed, leading to the development of the periodic table.
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.
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
Is average a compound word?
no
What is the resemblance between newland classification element and music?
what is the resemble between newland classification element and music
What properties were the basis of the triad system?
The triad system, developed by Jons Jakob Berzelius in the early 19th century, is based on the properties of atomic mass, valency, and chemical behavior. It organizes elements into groups of three, where the atomic mass of the middle element is approximately the average of the other two, and they exhibit similar chemical properties. This system aimed to demonstrate periodic relationships among elements and laid the groundwork for the later development of the periodic table.
What is the weight average molecular weight of the compound in question?
The weight average molecular weight of the compound is the average of the molecular weights of all the molecules in the sample, weighted by their relative abundance.
