Oxygen is a common element that exists in two forms, oxygen gas and ozone gas. Write the electron configurations for the oxygen atom and the oxygen ion using spdf notation.

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.
