Ten (10)grams methane gas combines with oxygen gas to form water and carbon dioxide. 2. What is the mass in grams of H2 gas when 4.0 moles of HCl is added to the reaction? The by-product is magnesium fluoride (MgF2). What is the Kelvin temperature of a system in which 4.50 mol of a gas occupy 0.250 L at 4.15 atm? The reaction takes place at 750 mm Hg, A 40.0 g sample of zinc is allowed to react with excess hydrochloric acid. Calculate the amount of HCl left after the reaction, 7.
