(Originais Teachy 2023) - Question Medium of Chemistry

A company has developed a new hydrogen-based fuel that, when burned, produces water vapor (H2O) as the only resulting product. The chemical reaction that occurs in this process can be represented as follows: 2H2(g) + O2(g) → 2H2O(g). Suppose you work for a company that plans to use this fuel in its vehicles and needs to calculate some information related to the process. a) If a vehicle uses 4.5 grams of hydrogen to travel a certain distance, how many grams of water will be formed? b) If your vehicle needs 112 liters of oxygen at 25°C and 1 atm to travel a specific distance, how many grams of hydrogen will be consumed? c) Considering that the density of air is 1.29 g/L, what is the volume occupied by the gases involved in the reaction when 10 grams of hydrogen are burned?
