A 0.5347 g sample of cinnamaldehyde, a compound that contains only carbon, hydrogen and oxygen and has the fragrance of cinnamon was combusted in a flow of excess oxygen. The carbon dioxide collected had a mass of 1.6024 g and the water collected had a mass of 0.2916 g. When cinnamaldehyde was vaporized in a 254.00 mL flask at 100.0 °C and 1.044 bar, the vapour was found to have a mass of 1.1302 g. What amount of hydrogen (H), in moles, is present in the water (H2O) produced?

When limestone (solid CaCO3) is heated, it decomposes into lime (solid CaO) and carbon dioxide gas. This is an extremely useful industrial process of great antiquity, because powdered lime mixed with water is the basis for mortar and concrete - the lime absorbs CO₂ from the air and turns back into hard, durable limestone. Suppose some calcium carbonate is sealed into a limekiln of volume 550. L and heated to 520.0 °C. When the amount of CaCO3 has stopped changing, it is found that 8.46 kg have disappeared. Calculate the pressure equilibrium constant K, this experiment suggests for the equilibrium between CaCO3 and CaO at 520.0 °C. Round your answer to 2 significant digits. P Note for advanced students: it's possible there was some error in this experiment, and the value it suggests for K does not match the accepted value. 0 X
