I am in the lab seeing if adding sugar to water affects how long it takes the water to boil. In the first test I boil 100 mL of water only in a beaker over a Bunsen burner and observe it takes 5:15 mins to boil. Next I add 2 grams of sugar to 100 mL of water and stir to dissolve, then boil making sure everything is the same. This time it takes 7:05 mins to boil the sugar-water mix. Next I add 4 grams of sugar to 100 mL of water. This time it takes 10:35 mins to boil the sugar-water mix. What could we infer about the effect sugar has on the boiling time of water?

Look at the reaction below: ca(hco3)2 --> caco3 + co2 + h2o first, balance the reaction. once balanced, use dimensional analysis or another method to find out how many moles of carbon dioxide will be produced if we start with 16.5 moles of calcium bicarbonate (calcium hydrogen carbonate). = mol of co2 number needs to be reported to three significant figures.
