What are the values of x, y and z respectively in the following in the following equation? \(MnO_{2(s)} + xHCI_{(aq)} → MnCI_{2(g)} + yHO_{(l)} + zCI_{2(g)}\)
4,1,2
1,2,1
2,1,2
4,2,1
Spiegazione
\(MnO_{2(s)} + xHCI_{(aq)} → MnCI_{2(g)} + yH_2O_{(l)} + zCI_{2(g)}\)
compare the number of each atom of the elements on both sides of the chemical equation.
x = 4, y = 2 and z = 1
