A carbon compound 'P' on heating with excess conc. H, So, forms another carbon compound 'Q' which on addition of hydrogen in the presence of nickel
catalyst forms a saturated carbon compound 'R'. One molecule of 'R' on
combustion forms two molecules of carbon dioxide and three molecules of water.
Identify P, Q and R and write chemical equations for the reactions involved.​

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!
