Gọi \(m_{KClO_3}=m_{KMnO_4}=m_{MnO_2}=a\left(mol\right)\)
`=>` \(\left\{{}\begin{matrix}n_{KClO_3}=\dfrac{a}{122,5}\left(mol\right)\\n_{KMnO_4}=\dfrac{a}{158}\left(mol\right)\\n_{MnO_2}=\dfrac{a}{87}\left(mol\right)\end{matrix}\right.\)
PTHH: \(2KClO_3\xrightarrow[MnO_2]{t^o}2KCl+3O_2\)
\(\dfrac{a}{122,5}\)-------------------->\(\dfrac{3a}{245}\)
\(2KMnO_4\xrightarrow[]{t^o}K_2MnO_4+MnO_2+O_2\)
\(\dfrac{a}{158}\)--------------------------------->\(\dfrac{a}{316}\)
\(KClO_3+6HCl\rightarrow KCl+3Cl_2+3H_2O\)
\(\dfrac{a}{122,5}\)------------------------>\(\dfrac{6a}{245}\)
\(2KMnO_4+16HCl\rightarrow2KCl+2MnCl_2+5Cl_2+8H_2O\)
\(\dfrac{a}{158}\)---------------------------------------------->\(\dfrac{5a}{316}\)
\(MnO_2+4HCl\rightarrow MnCl_2+Cl_2+2H_2O\)
\(\dfrac{a}{87}\)------------------------------>\(\dfrac{a}{87}\)
`=>` \(\left\{{}\begin{matrix}\dfrac{3a}{245}>\dfrac{a}{316}\\\dfrac{6a}{245}>\dfrac{5a}{316}>\dfrac{a}{87}\end{matrix}\right.\)
`=> KClO_3` đều cho nhiều `Cl_2` và `O_2` hơn
