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.

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
