HELP PLEASE!! How many moles of iron (III) oxide are produced when 0.275 moles of iron is reacted?

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.

The first element on the periodic table of elements is carbon. a. true b. false
