Answer:
The balanced equation is:
\(H_3PO_4 + 3 RbOH \longrightarrow 3 H_2O +Rb_3PO_4\)
Explanation:
Hi, step by step:
1) Balance the Rb:
\(H_3PO_4 + 3 RbOH \longrightarrow H_2O +Rb_3PO_4\)
2) Balance the phosphate:
\(1 H_3PO_4 + 3 RbOH \longrightarrow H_2O +Rb_3PO_4\)
3) Balance the water:
\(1 H_3PO_4 + 3 RbOH \longrightarrow 3 H_2O +Rb_3PO_4\)
