Is fe2o3+h2--2fe+3h2o balanced or unbalanced?

hydrogen is not balanced

the right balanced equation is

Fe2O3 + 3 H2 -> 2Fe + 3H2O

The alkali metals are lithium, sodium, potassium, rubidium, cesium and francium, and the alkaline earth metals are beryllium, magnesium, calcium, strontium, barium and radium. Hydrogen is placed on the periodic table above group 1a but is not considered part of the group.
