What is the mass of carbon in 290 g of CO2?

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

50 pts plz what is the physical state of matter of baking soda.

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!
