Briefly describe the difference in the Mendeleev’s table and modern periodic table?
Expert
Periodic table is now arranged in the order of raising atomic numbers. Furthermore, it is stated that the modern table makes it simpler to read and learn. The manner that it is set up now permits scientists to make modifications whenever essential.

Ethanol is manufactured from carbon monoxide and hydrogen at 600 K and 20 bars according to the reaction2 C0(g) + 4 H2(g) ↔ C2H5OH(g) + H2O (g)The feed stream contains 60 mol% H2, 20 m
The excluded volume b, introduced by vander Wall's as an empirical correction term, can be related to the size gas molecules. To do so, we assume the excluded volume is the result of the pairwise coming together of molecules. This assumption is justified when b values
