A sugar cube coated with cigarette ash readily ignites and burns. All of the cigarette ash remains unchanged after the reaction, but the sugar is burned completely. Manufacturers of cigarettes add chemicals that support burnung into the cigarettes. The factor that caused this change in rate is the ☐ a. presence of a catalyst in the ash , increase in surface area ○ b.i c. nature of reactants d. increase in concentration 14K

Apply Students conducted a lab to investigate limiting and excess reactants. The students added different volumes of sodium phosphate solution (Na3PO4) to a beaker. They then added a constant volume of cobalt(ll) nitrate solution (CO(NO3)2) stirred the contents, and allowed the beakers to sit overnight. The next day, each beaker had a purple precipitate at the bottom. The students decanted the supernatant from each beaker, divided it into two samples, and added one drop Of sodium phosphate solution to one sample and one drop of cobalt(ll) nitrate solution to the second sample. Their results are shown in Table 11.5. a. Write a balanced chemical equation for the reaction. b. Based on the results, identify the limiting reactant and the excess reactant for each trial.
