Answer:
Which combination are you talking about?
Answer:
D
Explanation:
A, B and C are incorrect since the greater the pH value, the more alkaline a solution is, and the pH of water is 7.
In the statement D, the pH of NaOH solution is 13 usually, so the given solution is less alkaline than NaOH solution, and I think of the same concentration is somewhat unnecessary.
Answer:
D
Explanation: In order to separate liquids with similar boiling points,theoretical plates are the ones that must be maximized because two liquids would be at equilibrium with all properties being the same
The statement which correctly describes periodic trends in ionization energy is: B. Ionization energy generally increases from bottom to top and left to right.
A Periodic table is an organized tabular array of all the chemical elements arranged in order of increasing atomic number (in rows).
Ionization energy can be defined as the minimum energy required to remove (detach) an electron from a neutral atom in its gaseous state.
Generally, ionization energy tend to increase from left to right across a period on the periodic table and from bottom to top in each group of a periodic table.
This increase is mainly because the atomic radius of chemical elements generally decreases across the periodic table, typically from alkali metals (group one elements) such as sodium, lithium and hydrogen to noble gases (group eight elements) such as neon, helium, and argon. Thus, the periodic trend for ionization energy is from left to the right and bottom to top of the periodic table.
