Yes Nitrogen is a pure substance because pure substances are both compounds and elements. Nitrogen is an element.
nitrogen gas is BASICALLY JUST PLAIN NITROGEN AND THUS IT IS A PURE SUBSTANCE.
Nitrogen is an element. It can be there as gas, liquid or solid.
Nitrogen (gas or liquid) is a chemical element not a mixture.
It is a pure element
Nitrogen is an element it has an atomic number of 7
Nitrogen is an element(a pure substance) itself. So, it comprises only of 1 element, which is nitrogen.
NH3, which stands for ammonia, is a pure substance. It is a compound composed of two elements, nitrogen (N) and hydrogen (H), in a fixed ratio, and it has uniform properties throughout.
most commonly by the fractional distillation of liquid air
from the actual sense water is not a pure substance, but if you are classifying it as either heterogenous or hoemogenous, then it is hoemogenous and not heterogenous, now heterogenous are substance that contains different forms eg liquid and solid. But water has one form (liquid)

nitrogen gas is BASICALLY JUST PLAIN NITROGEN AND THUS IT IS A PURE SUBSTANCE.
There is neither a solvent nor solute in liquid nitrogen as it is not a solution. Liquid nitrogen is pure elementalnitrogen in liquid form.
A mixture can be defined as a material composed of two or more different substances that are not chemically combined. This makes nitrogen a pure substance.
it s pure liquid.
yes
Nitrogen (N) is a chemical element, not a solution; nitrogen can be obtained as a very pure gas.
Nitrogen is an element it has an atomic number of 7
Air is a mixture of gasses, about 78% nitrogen, 21% oxygen and then a dash of others. Nitrogen OTOH is one of the elements out of the Periodic Table, which I guess is what you mean with a pure substance.
Nitrogen is not a mixture it's an element.
Yes, water (as a liquid, solid or gas) can be obtained as a pure substance; but frequently water contain many impurities.
Nitrogen is an element(a pure substance) itself. So, it comprises only of 1 element, which is nitrogen.
