In terms of energy what kind of system is a sealed glass terrarium on a windsill?
Snezhnost [94]
If the sealed glass is permeable to sunlight or to transfer of heat will be an open system, but if the sealed glass is a thermic glass and doesn't allow exchange of heat and exchange of solar energy (for example a mirrored glass that reflect the sunlight) and the terrarium is not exchanging energy with the surroundings will be a closed system. It is a question that doesn't specify too many details about the system in the study. It is hard to give a final answer without making some assumptions.

Consider a possible triatomic molecule containing a nitrogen, oxygen, and fluorine atoms for the following questions.
STALIN [3.7K]

Answer:

a) nitrogen

b) nitrogen =5

Oxygen = 6

Fluorine =7

Explanation:

Usually, if we have two or more elements in a compound, the central atom in the compound is the atom having the least value of electro negativity.

If we consider fluorine, oxygen and nitrogen; nitrogen is the least electronegative of the trio hence it should be the central atom of the triatomic molecule.

The number of valence electrons on the valence shell of each atom is shown below;

nitrogen =5

Oxygen = 6

Fluorine =7
