Modern periodic table and Mendeleevs table
Differentiate between the modern periodic table and Mendeleevs table?
Expert
The periodic table is currently arranged in an order of increasing atomic numbers. In addition, it is believed that the modern table makes it easier to learn and read. The method that it is set up now permits scientists to make modifications if necessary.
Explain how dissolving the Group IV carbonate precipitate with 6M CH3COOH, followed by the addition of extra acetic acid, establishes a buffer with a pH of approximately
I) Sulphur dioxide (SO2) with a volumetric flow rate 5000cm3/s at 1 bar and 1000C is mixed with a second SO2 stream flowing at 2500cm3/s at 2 bar and 200C. The process occurs at steady state. You may assume ideal gas behaviour. For SO2 take the heat capacity at constant pressure to be CP/R = 3.267
