Hydrogen gas a potential future fuel, can be formed by the reaction of methane with water as per to the balanced equation
CH4(g) + H2O(g)--> CO(g) + 3H2(g)
In a particular reaction 0.984 mol CH4 mixes with 23.3 L of water vapor measured at 0.9237atm and 398 K. The reaction produces 26.2 L of hydrogen gas at STP. Explain what is the percent yield of the reaction?
Suppose a sample of Zn(s) is reacted with HCl(aq) to form hydrogen gas. Explain the H2 gas bubbles out of aqueous solution and is collected in a 552.0mL container at 618.3 Torr and 25 C. Explain how many grams of zinc reacted. Be sure to account f..
