Question

Under certain circumstances, carbon dioxide, CO2(g), can be made to react with hydrogen gas, H2(g), to produce methane, CH4(g), and water vapor, H2O(g): CO2(g)+4H2(g)→CH4(g)+2H2O(g)

How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 53.6 moles of water vapor? Express your answer with the appropriate units. For example, write the unit moles as mol.

Answer 1

107.2 moles of Hydrogen gas is required.

The balanced equation for the reaction is | Co, q+ quạ) – CH4 + 2 H 6) 1 4 1 2 =) One mole of Co, + 4 moles of Ha gas 1 mole of methane $ 2 miles of Water given that c is in excess amount. & 53.6 miles of hogy has to be formed. from the equation, CO₂ + utta → CHu + 2H2O Vардиъ • 53.6 miles A miles of He 4 g => 4= 536*4 = 53.6x2 = 107.2 moles of He gas is required
