To obtain 1 mol of hydrogen from electrolyzed water, how much g of water is needed? How many grams of oxygen are produced at the same time To obtain 1 mol of hydrogen gas from electrolyzed water, ask what mass of electrolyzed water is required? How many grams of oxygen are produced at the same time
18 G H2O 16 g O2
2H20===2H2+02
2 2 1
1 1 0.5
Hydrogen can be obtained by electrolysis of water, but a large amount of electric energy will be consumed. If () is used to decompose water, it will be a good way to develop hydrogen energy in the future
Sunlight, geothermal
