# How would you balance the following equation: Ba + H2O --> Ba(OH)2 + H2?

$B a \left(s\right) + 2 {H}_{2} O \left(l\right) \rightarrow B a {\left(O H\right)}_{2} \left(a q\right) + {H}_{2} \left(g\right) \uparrow$
As for any chemical reaction, it is balanced stoichiometrically. What does "$\text{stoichiometric}$" mean. It means that for every reactant particle, there is a corresponding product particle. Is that true for the given equation? How would I represent the corresponding reaction between potassium and water?
