Answer:
NaH(s) + H2O(l) ------> NaOH(aq) + H2(g)
2Al(s) + 3Cl2(g) -----> 2AlCl3(s)
Explanation:
The rule of thumb in balancing chemical reaction equation is that the number of atoms of each element on the reactant side must be the same as the number of atoms of the same element on the product side. Only then can any reaction equation be seen as balanced.
For example there are two aluminum atoms on both sides of the reaction equation and six chlorine atoms on both sides of the reaction equation. Hence the reaction equation is balanced.
