Balance the equation below by placing the correct coefficients in the blanks. Your response should list the coefficients in order from left to right, separated only by commas; no spaces. If no coefficient belongs in a blank, represent it with a “1”. For example the equation 2 H2O  → 2 H2+O2 would be represented as 2,2,1.  ____H3(PO4)  +  ____ Rb(OH)   →   ____H2O + ____Rb3 (PO4)
