Answer:
La Nina
Explanation:
La Nina -
The word La Nina means " the little girl " , in spanish language .
La Nina , is an ocean - atmospheric process , which occurs in the eastern equatorial Pacific Ocean .
It is exactly opposite of El Nino , which means " the little boy " .
In the phase of La Nina , the temperature of the eastern equatorial Pacific Ocean becomes lower than the usual temperature by around 3°C to 5°C .
This phase of La Nina is for around 5 months in an year .
Hence , from the given statement of the question ,
The correct term is La Nina .
Answer: 31.55 g
Explanation:
- The mass number of Fluoride atom (F) = 18.99 g/mol, so mass number of fluorine gas (F2) = 37.98 g/mol.
- 1 mole of (F2) [which has 37.98 g/mol] contains Avogadro’s number of molecules (6.02×10^23 molecules),
so 1 mole of (F2) with 37.98 g/mol → 6.02×10^23 molecules.
- Using cross multiplication,
37.98 g/mol of (F2) → 6.02 ×10^23 molecules
? → 5.00 ×10^23 molecules
Hence the mass of 5.00×10^23 molecules of F2 = (37.98 × 5.00 × 10^23) / 6.02 ×10^23 = 31.55 g..
