Briefly describe the significance of Mendeleev’s periodic table.
Expert Solution & Answer
Interpretation Introduction
Interpretation:
The significance of Mendeleev’s periodic table has to be described briefly
Concept Introduction:
In Mendeleev’s periodic table the elements were arranged by increasing number of atomic weight. Group of elements with similar properties were arranged together.
Mendeleev’s classification
In Mendeleev’s classification the elements were grouped according to their properties. Equal importance was given for the undiscovered elements; some gaps were left for the elements yet to be discovered.
Explanation of Solution
In Mendeleev’s periodic table the elements were arranged by increasing order of atomic mass, group of elements with similar properties were placed in to vertical column in the table.
Mendeleev named eka-aluminium and eka-silicon for the undiscovered elements and predicted its properties, Gallium and Germanium were discovered and its properties matched the predicted properties of eka-aluminium and eka-silicon respectively.
Conclusion
The significance of Mendeleev’s periodic table was described briefly.

Bicarbonate is crucial for the control of body pH (for example, blood pH:
7.4). A more self-indulgent use is in baking soda, where it serves as a
source of CO2 CO₂ 2 gas, which gives bread and pastry their fluffy
constituency.
(i) Draw at least one additional resonance form.

(ii) Using curved "electron-pushing" arrows, show how these Lewis structures may
be interconverted by movement of electron pairs. (iii) Determine which form or
forms will be the major contributor(s) to the real structure of bicarbonate,
explaining your answer on the basis of the criteria in Section 1-5.

given a kitchen scale.
Which of these properties would correlate with the mass of a baking ingredient like
eggs or milk? Check all that apply.
depth of color
viscosity
