Chapter 13, Problem 141AP

onsider the following unbalanced chemical equation:

msp;  ${\text{Cu}}_{\text{2}}\text{S}\left(s\right)+{\text{O}}_{\text{2}}\left(s\right) {\text{Cu}}_{\text{2}}\text{O}\left(s\right)+{\text{SO}}_{\text{2}}\left(g\right)$

at volume of oxygen gas, measured at $\text{27}.\text{5 }°\text{C}$and $0.\text{998}$atm, is required to react with $\text{25 g}$of copper(l) sulfide? What volume of sulfur dioxide gas is produced under the same conditions?
