Which variables are unknown? pressure volume temperature moles

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.

An experimental procedure requires a 10 ml of acid to be dissolved

Consider the four elements above. which one of these elements will combine with oxygen in a 1: 1 ratio?
