Question

How do you balance these equations: `?Be(OH)_2 -> ?BeO + ?H_2O` and `?MnS + ?HCl -> ?H_2S + ?MnCl_2`?

Answer 1

`Be(OH)_2(s) + Delta rarr BeO(s) + H_2O(g)`

Explanation:

And..........

`MnS(s) + 2HCl(aq) rarr MnCl_2(aq) + H_2S(aq)`

Are these equations balanced with respect to mass and charge?
