Answer: 6.75 moles of 
can be produced from 13.5 moles Na
Explanation:
The balanced chemical equation for formation of from Na is:
According to stoichiometry :
4 moles of Na give = 2 moles of
Thus 13.5 moles of 
give =
of
Thus 6.75 moles of can be produced from 13.5 moles Na
The molecules of the cold element are going to be closer together and still than the molecules of the hot element because the heat energy causes the molecules to be stimulated and to move.
<h3>How do molecules act at different temperatures?
</h3>
In the image you can see the behavior of the molecules when they are in different environments. On the right you see the cold molecules and on the left the hot molecules that are characterized by the following characteristics:
Cold molecules:
- Molecules together.
- Molecules with little movement.
Hot molecules:
- Separate molecules.
- Molecules with active movement.
A simple example to understand this behavior of molecules is water because:
- When water is frozen its molecules are almost static and close together.
- When the water is liquid and it is heated, the molecules move and that is why the water has bubbles, its molecules are separated.

It is essential for accurate results that the correct volume of blood is sampled to achieve a correct concentration (and dilution, if liquid heparin is used), and that blood and anticoagulant are well mixed immediately after sampling.
One day (24 hours), because one rotation of earth on its axis is the position of the countries to the sun shifting, thus resulting in the periods of sun and moon, (the day and the night).
Answer: ATP Adenosine triphosphate
Explanation: During light reaction plants produce glucose and as well as ATP and NADPH as another products. Now during the Dark or light independent reaction there is no presence of light energy to fuel the process so ATP is used as an alternative to fix CO2 molecules.
