an insoluble precipitate was formed when a solution of 1.000 L of 0.750 M sodium carbonate (Na2CO3) was mixed with .5000 L of 1.50 M solution of iron (III) nitrate (Fe(NO3)3). what is the concentration of all ions present after the reaction is complete?

a solid sample of impure Ba(OH)2 is added to 400.0 mL of 0.5000 M of aqueous HBr, a strong acid. the remaining solution was acidic. it was then titrated to equivalence point with 120.0 mL of 0.5000 M of NaOH solution. what mass of pure Ba(OH)2 was present...

a solid sample of impure Ba(OH02 is added to .4000L of .5000M of HBr. the remaining solution was acidic, it was then titrated to equivalence point with .1200L of .5000M NaOH. what mass of pure Ba(OH)2 was present in the sample?

why might you not observe a reaction even though an activity series indicates it should occur?

How many Lister of Carbon Dioxide gas measured at STP can be produced by the decomposition of 15.0g of Sodium Bicarbonate to give Sodium Carbonate, water, and Carbon Dioxide gas?
