# Is this equation balanced? 4KOH + 2BaCl_2 -> 4KCl + Ba(OH)_2 If not, how would you balance it?

Should not you tell us?

#### Explanation:

$4 K O H \left(a q\right) + 2 B a C {l}_{2} \left(a q\right) \rightarrow 4 K C l \left(a q\right) + 2 B a {\left(O H\right)}_{2}$...or more simply....

$2 K O H \left(a q\right) + B a C {l}_{2} \left(a q\right) \rightarrow 2 K C l \left(a q\right) + B a {\left(O H\right)}_{2} \left(s\right) \downarrow$

And if you add up the product masses, these are precisely and necessarily equal to the reactant masses, i.e. $320.5 \cdot g$.. All chemical reactions obey this principle.

For each equation, $\text{garbage out equals garbage in}$...i.e mass is conserved, and also charge is conserved....
