Based on the chemical reaction: N2(g) + 3H2(g) → 2NH3(g), which substance takes up the most space?
See the exact question above by Veronica.
To determine which substance takes up the most space in the given chemical reaction, we need to consider the stoichiometry or the ratio of the moles of each substance involved.
In the balanced equation, the stoichiometric ratio shows that for every 1 mole of nitrogen gas (N2), we need 3 moles of hydrogen gas (H2) to produce 2 moles of ammonia gas (NH3).
Since gases expand to fill the available volume, the number of moles of each gas will determine their relative volumes. In other words, the gas that has the highest number of moles will take up the most space.
In this case, the ratio of N2 to H2 is 1:3, meaning for every 1 mole of nitrogen gas, we have 3 moles of hydrogen gas. When the reaction occurs, these 3 moles of hydrogen gas combine to form 2 moles of ammonia gas.
Based on the stoichiometry, we can conclude that the substance that takes up the most space in this reaction is hydrogen gas (H2), since we start with more moles of hydrogen gas compared to nitrogen gas.
Therefore, in terms of volume, hydrogen gas (H2) takes up the most space in the chemical reaction N2(g) + 3H2(g) → 2NH3(g).
