Can somebody please answer this for me 4NH3+6NO --> 5N2 + 6H20

When a student runs this reaction in their chemistry lab, they notice that they run out SO quickly and some NH3 is left in the container. Which reactant is the limiting reactant?

N2

NH3

NO

water

NO

Explanation:

Water and N₂ cannot be the answer because they are products of the reaction, not reactants.

The fact that some ammonia (NH₃) is left in the container once the reaction is finished tells us that NH₃ is the reactant in excess.

The remaining reactant is thus the limiting reactant. The correct answer is NO.

its first and third is your answer i did the qustion the fourth isnt right

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.
