Methanol, CH3OH, which is used in racing cars and in fuel cells, can be made by the reaction of carbon monoxide and hydrogen.
CO(g) + 2 H2(g) → CH3OH(l)
Suppose 373 g of CO and 67.0 g of H2 are mixed and allowed to react. What mass of methanol can be produced? What mass of the excess reactant remains after the limiting reactant has been consumed?
_____________ g CH3OH
____________ g excess reactant
2) For this reaction, 4.35 g hydrogen gas reacts with 40.2 g iodine.
hydrogen (g) + iodine (s) hydrogen iodide (g)
What is the maximum mass of hydrogen iodide that can be formed? ____________ g
What is the FORMULA for the limiting reagent?
What mass of the excess reagent remains after the reaction is complete?___________ g
3)Consider this reaction, which occurs in the atmosphere and contributes to photochemical smog:
SO2(g) + H2O(l) →H2SO3(g)
If there is 14.24 g SO2 and excess H2O present, the reaction yields 14.4 g H2SO3. Calculate the percent yield for the reaction.
_______________________%
4)Glucose, C6H12O6, reacts with oxygen to give CO2 and H2O. What mass of oxygen (in grams) is required for complete reaction of 40.0 g of glucose? What masses of carbon dioxide and water (in grams) are formed?
_______g O2
_________g CO2
_________ g H2O
