Balance the given molecular equations in aqueous solution with coefficients and phases for each species. If you determine that a species should have a coefficient of 1, you must indicate this with the "1" label. Do not leave the coefficient space blank for any species in the balanced equation. 1 2 3 4 5 6 s aq

K2SO4 ( )+ Pb(NO3)2 ( ) → KNO3 ( )+ PbSO4 ( )
Ca(C2H3O2)2 ( )+ (NH4)2CO3 ( ) → CaCO3()+ NH4C2H3O2()
Li3PO4( )+ BaCl2 ( ) → LiCl ( ) + Ba3(PO4)2 ( )
MgBr2( ) + NaOH ( ) → Mg(OH)2 ( ) + NaBr ( )

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.
