# How do you write a balanced overall reaction given the following unbalanced half-reactions?

## $L i \to L {i}^{+}$ $B {a}^{+ 2} \to B a$

Well any equation must conserve mass and charge, so............

#### Explanation:

$L i \rightarrow L {i}^{+} + {e}^{-}$

$B a \rightarrow B {a}^{2 +} + 2 {e}^{-}$

These equations represent the oxidation of the metals to their typical oxidation state. Are mass and charge balanced? What do I mean by this?

$2 L i + B {a}^{2 +} \rightarrow 2 L {i}^{+} + B a$
