Consider the following acid/base reaction CO2−3 + 2 H+ → H2O + CO2
that produces CO2 gas. 7.8 L of CO2 is
collected at STP. What is the molarity of the
HCl solution used in the reaction if 123 mL of
HCl was needed?
Answer in units of M.

Identify the limiting reactant when 9.65-g h2so4 reacts with 6.10-g of naoh. the equation is h2s04 + 2naoh = 2h2o + na2so4• what is the theoretical yield of na2so4, in grams? • how much of the excess reagent will remain after the reaction has been completed? • if 10.5-g of na2so4 are actually recovered experimentally, what is the percent yield?
