It's to do with the intermolecular bonds (the van Der Waals forces). If they are strong, the substance exists as a solid as the particles are held together with a strong force. If however they are weak, the substance will be a gas.
I would have to say KCl.
N2. In hydrazine, H2N-NH2, the two nitrogens are bonded with a single bond, whereas in nitrogen, a triple bond is present between the two nitrogens.
This equation is:NH4NO2 = N2 + 2 H2O
yes, the burning strip of Magnesium in nitrogen atmosphere produces solid Magnesium nitride, 3Mg + N2 = Mg3N2
nitrogen is a gas (N2)
yup. nitrogen gas-- N2
It is an element. Since any temperature is "natural", the physical state is meaningless. It can be anything from a Bose-Einstein condensate (unlocalizeable), a solid, a liquid, a gas, or a plasma... and be "natural" for that temperature. At standard temperure and pressure, it is a very stable diatomic gas (N2). Nitrogen's natural stage is N2 gas. It is diatomic and can only exist with 2 nitrogen molecules, so it must be N2 not N.
At room temperature N (N2) is a gas. N, by itself, does not exist at room temperature and standard pressure. It exists as the diatomic gas, N2.
3Ca + N2 = Ca3N2
Nitrogen can be obtained as a solid at very low temperature, under -210 0C. At room temperature nitrogen is a gas.

no
N2 is not solid at room temperature. This is one of the diatomic elements that are in the gaseous state at room temperature.
The substances represented by the chemical formula N2 is nitrogen gas.
