Verified step by step guidance1
Identify the reactants and products in the given chemical equation: The reactants are hydrogen gas (H2) and nitrogen gas (N2), and the product is ammonia (NH3).
Determine the type of reaction: This reaction involves the combination of hydrogen and nitrogen to form ammonia, which is a synthesis reaction.
Check for electron transfer: In this reaction, hydrogen and nitrogen are combining to form a new compound, indicating that electrons are being shared between the atoms, which is characteristic of a redox reaction.
Analyze the oxidation states: In the reactants, hydrogen is in the 0 oxidation state, and nitrogen is also in the 0 oxidation state. In the product, ammonia, hydrogen is in the +1 oxidation state, and nitrogen is in the -3 oxidation state, indicating a change in oxidation states.
Conclude the type of reaction: Since there is a change in oxidation states, this reaction is a redox reaction, where hydrogen is oxidized and nitrogen is reduced.
