The fizz produced when a tablet of alka-seltzer dissolves in h2o comes from the reaction of sodium carbonate,, nahco3, and citric acid, c6h8o7: . 3nahco3+c6h8o7--> 3co2+3h2o+na3c6h5o7. supposed the tablet containing 1.00g of sodium bicarbonate and 1.00g of citric acid reacts to completion. how many grams of co2 are produced and how many grams of the excess reagent remain when the reaction is complete?

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
