The number of moles and the mass of barium peroxide, BaO2, needed to produce 1.700 kg of barium oxide, BaO (O2is the other product.)
Added by Daja L.
Step 1
First, we need to find the balanced chemical equation for the reaction between barium peroxide (BaO2) and barium oxide (BaO). The balanced equation is: 2 BaO2 → 2 BaO + O2 Show more…

A sample of $20.00 \mathrm{~g}$ of barium reacts with oxygen to form $22.38 \mathrm{~g}$ of a mixture of barium oxide and barium peroxide. Determine the composition of the mixture.
Find the mass of barium metal (in grams) that must react with O2 to produce enough barium oxide to prepare 1.0 L of a 0.10 M solution of OH-. (Hint: Barium metal reacts with oxygen to form BaO; BaO reacts with water to form Ba(OH)2.)
Find the mass of barium metal (in grams) that must react with $\mathrm{O}_{2}$ to produce enough barium oxide to prepare $1.0 \mathrm{~L}$ of a $0.10 \mathrm{M}$ solution of $\mathrm{OH}^{-}$. (Hint: Barium metal reacts with oxygen to form $\mathrm{BaO} ; \mathrm{BaO}$ reacts with water to form $\left.\mathrm{Ba}(\mathrm{OH})_{2} .\right)$
