Final answer:
To find out how many moles of H₂O are formed, we need to apply stoichiometry of the given reactions. For instance, if we know that 13.8 moles of O₂ can produce 27.6 moles of H₂O, we conclude that each mole of O₂ generates two moles of H₂O. Hence, 154 moles of O₂ would yield 308 moles of H₂O.
Step-by-step explanation:
To determine how many moles of H₂O will be formed when various reactants are involved, we should start by looking at the stoichiometry of the reactions provided. For example:
- The reaction between hydrogen and oxygen: 2 H₂(g) + O₂(g) → 2 H₂O(g).
- For the combustion of pentane C5H12: The balanced equation must be determined before finding out the moles of water produced.
- For the reaction of ammonia with oxygen: NH3 + O₂ → N₂ + H₂O, after balancing, we can find the moles of water produced from 1.65 mol of NH3.
Particularly, if we know that 13.8 moles of O₂ produce 27.6 moles of H₂O, following the stoichiometry which indicates that each 1 mol of O₂ produces 2 mol of H₂O, we can deduce that for every mole of reactant O₂, two moles of product H₂O are formed.
For the given exercise where 154 mol of O2 react, the direct stoichiometric relationship suggests that 2 moles of H₂O are produced per 1 mol O₂. Therefore, 154 mol of O₂ would produce 308 moles of H₂O.
