Answer:
Standard boiling point
Explanation:
Note that there are 2 major units of pressure except Pa .
- bar
- atm
At 1 atm pressure the boiling temperature is called normal boiling point.
At 1 bar pressure the boiling temperature is called standard boiling point
Answer:
See explanation
Explanation:
According to Bohr's theory, when external energy is supplied to an atom, its electrons absorb energy and move from a lower energy level to a higher energy level.They quickly return to their original level and re-radiate the absorbed energy as a photo of light.
Hence, when an atom in ground state receives external energy, it becomes excited because energy is transferred to its electrons and they move from lower to higher energy level.
Answer:
Anther: It produces pollen.
Filament: It hold the anther.
Anther and filament together make the stamen.
Please link those observations so we can answer your question. have a good day <3
Answer is: below magnesium in group 2 or in group 1 (left from magnesium).
Reactivity series is an empirical progression of a series of metals, arranged by their reactivity from highest to lowest (alkaline metals have highest reactivity and Noble metals lowest reactivity).
This series are used to summarize information about the reactions of metals with acids or water, double displacement reactions (more reactive metals displace metals with lower reactivity) and the extraction of metals from their ores.
Sodium and potassium (group 1 - alkaline metal) are more reactive than magnesium.
Strontium and barium (group 2 in periodic table) are higher in this group from magnesium. Strontium is stronger reducing agent than magnesium, gives electrons easier.
