Final answer:
The simplest form of the chemical equation N2 + 3H2 → 2NH3 was identified by dividing the initial coefficients by the greatest common factor, which is crucial to maintain accurate mole ratios for the reaction.
Step-by-step explanation:
Balancing Chemical Equations
When balancing chemical equations, it's important to have the smallest whole number coefficients that represent the relative numbers of reactant and product molecules involved in the reaction.
Looking at the initial equation 3N2 + 9H2 → 6NH3, we identify that each coefficient can be divided by 3 to simplify the equation.
The simplified or preferred balanced equation becomes N2 + 3H2 → 2NH3, which maintains the correct mole ratios necessary for the reaction.
The process for reaching this balanced equation involves identifying the greatest common factor and dividing each coefficient by this number to achieve the smallest possible set of whole numbers, satisfying the law of conservation of mass.
The balanced equation is crucial as it specifies the mole ratio in which substances react and form products. In the given preferred equation N2 + 3H2 → 2NH3, one mole of nitrogen gas (N2) reacts with three moles of hydrogen gas (H2) to produce two moles of ammonia (NH3).
This balanced equation is essential for stoichiometric calculations and understanding chemical reactions.
