Balancing Chemical Equations

Balance the equation

$\mathrm{Na}(s)+\mathrm{H}_{2} \mathrm{O}(l) \longrightarrow \mathrm{NaOH}(a q)+\mathrm{H}_{2}(g)$

The unbalanced equation for the reaction between methane and bromine is

_$\mathrm {CH_4}(g)$ + _$\mathrm {Br_2}(l)\longrightarrow$ _$\mathrm {CBr_4}(s)$ + _$\mathrm {HBr}(g)$

Once this equation is balanced what is the value of the coefficient in front of bromine $\mathrm {Br_2}$?

(a) 1, (b) 2, (c) 3, (d) 4, (e) 6.
