The symbol N2 is for the diatomic molecule of nitrogen; it is not a mixture.
No. It is an element, which is homogeneous matter.
N2 (nitrogen gas) is not a mixture. It is a pure compound composed of two nitrogen atoms bonded together.
Ammonia is a compound, not a mixture. Household ammonia is a homogeneous mixture of ammonia and water.
Air is a common example of a homogeneous mixture of gases, consisting primarily of nitrogen and oxygen with smaller amounts of other gases such as carbon dioxide and argon. Another example is natural gas, which is a mixture of primarily methane but can also contain other hydrocarbons and impurities.
N2 and CO2
Gas containing two or more different kinds of molecules (or elements) always form homogeneous mixtures, like air (N2, O2, CO2, etc. etc., water and other vapours, perfumes, air-polluting gases, etc.etc.). If it is composed only with ONE kind of compound or element then it is pure.
To calculate the number of molecules of N2 gas, we need to use the ideal gas law. We first convert the volume to liters by dividing 500.0 ml by 1000. Then, we use the formula PV = nRT to find the number of moles of N2 gas in the sample. Finally, we multiply the number of moles by Avogadro's number (6.022 x 10^23) to find the number of molecules.
If nitrogen gas (N2) is added to a mixture of nitrogen (N2) and oxygen (O2), the overall reaction equilibrium and the partial pressures of the gases may change, but no new reactions would occur under standard conditions. The added N2 would increase the total pressure of the gas mixture without affecting the concentrations of O2 significantly, as nitrogen is inert in this context. This could lead to a decrease in the reaction quotient (Q) relative to the equilibrium constant (K) for any reactions involving N2 and O2, but since N2 is not reactive, the system would remain stable.
Nitrogen is a homogeneous substance. If you had, say, a bottle of compressed nitrogen gas, you'd have a whole bunch of diatomic molecules of nitrogen (N2) floating around in there. It'd be the same anywhere within the bottle, so it would not be hetrogeneous.
The standard enthalpy of formation for N2 gas is 0 kJ/mol.
No, nitrogen gas (N2) contains two nitrogen atoms.
N2 is nitrogen gas but technically its dinitrogen
