The reaction: H2C2O4 + CuO + Heat = ? This reaction was produced in organic elemental analysis to identify C and H. So I think CO2 is formed to react with Ca(OH)2 to giving CaCO3. Additionally was formed H2O, so I though H2 or H2O was produced. Is correct : = C2CuO4 + CO2 + H2 ?

For the reaction: 2HCl + Na2CO3→ 2NaCl + H2O + CO2 how much CO2 is produced at STP if 18.5 L of 1.15 M Na2CO3is used? The molar mass of Na2CO3is 106.01 g/mol. I know I have to use stoichiometry and possibly PV=nRT but I don't know what to use first. Do I start with 18.5L?
