Carry out the following calculation. Express the results in scientific notation and with the correct number ots 3.01e22 atoms + 1.19e23 atoms + 9.80e21 atoms =
atoms
Do not include units.

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.
