Answer: B) 2 (as indicated by electron distribution shown), but taking into account the real properties of this element, 4,7,8 also occur (see below).
Explanation:
This is the electron complement/atomic number of ruthenium, which actually has the structure [Kr] 5s1 4d7
Nevertheless, Ru does not form Ru(I) compounds and few Ru(II) compounds (RuCl2, RuBr2, RuI2). It also forms Ru(III)Cl3 and a larger number of Ru(IV) compounds, e.g. RuO2, RuS2. It also forms RuO4
Answer:
The correct approach will be the "Linguistic-relativity hypothesis".
Explanation:
- This theory can be defined as either the Hypothesis of Sapir-Whorf. This theory proposes whether our cognitive capabilities are influenced by languages as well as decide how we start behaving and communicate throughout society.
- Sapir Whorf explains these variations throughout the nature of human language throughout the manner a person understands the world.
Answer:

Answer:
step 2 then step 1 then step 3 then step 4
Explanation:
First boil it. Then identify the situation which is most conducive to boiling
.
While this, a liquid must overcome the attractive forces between molecules and the outside pressure pushing down on the liquid's surface.
The liquid will boil when there is weak intermolecular attraction and low atmospheric pressure.
Steps to be followed:
Pentane at high altitude
Hexane at high altitude
hexane at sea level
hexanol at sea level
