Question

What is the coefficient of H2O

H2O when the reaction is balanced? (Note: all coefficients must be integers).

Al(s)+H2O(l)→Al(OH)3(s)+H2(g)

What is the coefficient of  when the reaction is balanced? (Note: all coefficients must be integers).

Answer 1

Al _{( s )} + H2O _{( l )}→ Al(OH)_{3 ( s )} + H_{2 ( g )}

The balanced chemical equation is :

2 Al _{( s )} + 6 H2O _{( l )}→ 2 Al(OH)_{3 ( s )} + 3 H_{2 ( g )}

The coefficient of H₂O when the reaction is balanced is equal to 6.
