HELP ME PLEASE I HAVE BEEN STUCK ON THIS FOR WEEKS 90 POINTS

Balance this equation co2(g) + h2o (g) show that the balanced equation obeys the law if conversation of mass

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!

Chemical kinetics what was the rate of reaction in trial 3? choose the closest answer.
