Here are the answers to your questions: 8. To prepare and collect dry carbon (IV) oxide (CO_2), the setup typically involves: A conical flask containing marble chips (calcium carbonate) and a thistle funnel through which dilute hydrochloric acid* is added. A delivery tube leads the produced gas from the conical flask into a wash bottle containing concentrated sulfuric acid* to dry the CO_2. Another delivery tube then carries the dry CO_2 into a gas jar or test tube, where it is collected by downward delivery* (upward displacement of air) because CO_2 is denser than air. The reaction is: CaCO_3(s) + 2HCl(aq) CaCl_2(aq) + H_2O(l) + CO_2(g) 9. a) Graham's law of diffusion states that the rate of diffusion of a gas is inversely proportional to the square root of its molar mass (or density), provided the temperature and pressure are constant. Mathematically, for two gases A and B: Rate_ARate_B = sqrt((M_B)/(M_A)) where M_A and M_B are the molar masses of gases A and B, respectively. That's 2 down. 3 left today — send the next one.
