Answer: Water
Explanation: I don't see any graph attached, but water has a boiling point of 100C, which is where it would become gas, or water vapor. 0C is the freezing point of water, where it would become ice. Since 50C is in the middle, it would be considered liquid.
Hello!
Elements are made up of atoms, and elements combine to make compounds. Compounds are made up of molecules, and molecules are made up of atoms.
Nitrogen is an element. It could be made up of one or many atoms. A mixture is made up of compounds, so it is not the answer.
Molecules and compounds are made up of different atoms and elements, but nitrogen is not a molecule or a compound.
There is such a thing as a nitrogen atom, though.
Therefore, your answer would be 2) Atom.
I hope this helps!
Tri = 3
In adenosine triphosphate, aka ATP, there are 3 phosphate groups Adenine, a nitrogenous base.
Diphosphate on the other hand, has also phosphate groups attached to Adenine, however, the number of phosphate groups is 2.
Remember:
Mono = 1
Di = 2
Tri =3
