Ammonia is a colorless highly irritating gas with a sharp suffocating odor. It dissolves easily in water to form ammonium hydroxide solution which can cause irritation and burns. Ammonia gas is easily compressed and forms a clear, colorless liquid under pressure. It is usually shipped as a compressed liquid in steel cylinders. Ammonia is not highly flammable, but containers of ammonia may explode when exposed to high heat.
Air is mostly nitrogen, which is not flammable. Nitrogen is also non-reactive in general, so it doesn't support the combustion of other materials, either. After nitrogen, the most abundant gas in our air is oxygen. Here's where it gets complicated: Oxygen is also not flammable, but it is a high-energy gas that very readily oxidizes other materials. For something to burn, the reaction requires a fuel (the thing that burns) and an oxidizer like oxygen. Without the fuel, though, no combustion will take place no matter how high the concentration of oxygen is. Since air itself is not flammable, it is not a fuel and will not combust, spontaneously or otherwise.
