Dr. ray has developed a new way to remove oil from wetlands in the event of an oil spill. to test his new process, dr. ray builds a scale model of a wetland in his lab and pours a small amount of oil into it. he then observes the rate at which his process is able to remove the oil from the model. why did dr. ray use a model? a. because dumping oil in a real wetland would be dangerous. b. because real wetlands are too complicated for his process to work. c. because his model makes the process more complicated. d. because real wetlands are too large to be affected by oil.

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.
