Nitrogen monoxide is one of the main components of smog, and can be produced in a number of ways, including the reaction below: 4NH3(g)+5O2(g)→4NO(g)+6H2O(g)
If 22.0L of ammonia reacts with 32.0g of oxygen at SATP, what mass of nitrogen monoxide will be produced?

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.

you need to have a picture of the atom that way we can answer it

i believe the answer is three water molecules
