Ability to adapt to their environment?? there isn't much context to the question /:
Explanation:
The molecules move more slowly and their average kinetic energy decreases
The correct answer is : <span>Neon is inert because its outermost shell is complete.
Ne atomic number is 10 and has an electronic configuration of 1s</span>² 2s² 2p⁶.The outer shell is complete therefore Ne is inert, in other words inactive as its very stable with a complete outer shell.
Nitrogen is not inert as its atomic number is 7 and electronic configuration is 1s² 2s² 2p³. therefore valence electrons are 5, it needs 3 more electrons to gain the complete outer shell configuration. Therefore this statement is incorrect.
F has 7 valence electrons and needs only one more electron to complete its outer shell whereas O has 6 valence electrons and needs 2 electrons to complete its outer shell. Since F only needs one electron and O needs two electrons, F is more reactive than O therefore third statement is incorrect
F is more reactive than Ne as Ne is inert, however F needs to gain one electron and not lose, to fill its outermost shell therefore this statement too is incorrect
Answer:
Explanation:
Using the Ideal Gas Law we have and the number of moles n could be expressed as , where m is the mass and M is the molar mass.
Now, replacing the number of moles in the equation for the ideal gass law:
If we pass the V to divide:
As the density is expressed as , we have:
Solving for the density:
Then we need to convert the units to the S.I.:
Finally we replace the values:
