Answer: Quantitative Information from Balanced Equations
Chapter 1, Problem 62E(choose chapter or problem)
The reaction between potassium superoxide, \(KO_2\), and \(CO_2\),
4 \(KO_2\) + 2 \(CO_2\) \(\longrightarrow\) 2 \(K_2CO_3\) + 3 \(O_2\)
is used as a source of \(O_2\) and absorber of \(CO_2\) in self-contained breathing equipment used by rescue workers.
(a) How many moles of \(O_2\) are produced when 0.400 mol of \(KO_2\) reacts in this fashion?
(b) How many grams of \(KO_2\) are needed to form 7.50 g of \(O_2\)?
(c) How many grams of \(CO_2\) are used when 7.50 g of \(O_2\) are produced?
