Stoichiometry Practice
A) Na2SiO3 + 8 HE => H2SiF6 + 2 NaF + 3 H2O
1) How many moles of HE are needed to react in order to produce 1.5 moles
of water(H20)?
2) How many grams of Naf form when 0.500 mol of HE reacts?
3) How many grams of Na2SiO3 are needed to produce 10 g of NaF?
B) Pb(SO4)2 + 4 LINO3 = Pb(NO3)4 + 2 Li2SO4
1) How many grams of LINO3 will be needed to make 250 grams of Li2SO4?
2) How many grams of Pb(SO4)2 are needed to produce.75 mol of Pb(NO3)4?
C) 2 C6H10 + 17 02= 12 CO2 + 10 H2O
1) How many grams of Co, are formed from the reaction of 10 grams of
hexyne(C6H10)?
2) How many grams of water are produced from the reaction of 10 grams of
hexyne(C6H10)?

Steam reforming of methane ( ch4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. an industrial chemist studying this reaction fills a 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.
