Atank contains 1000 l of pure water. brine that contains 30 g of salt per liter of water is pumped into the tank at a rate of 25 l/min. the concentration of salt after t minutes (in grams per liter) is c(t) = 30t 40 + t . as t → ∞, what does the concentration approach?

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.
