Which is a spectator ion in the reaction between ba(no3)2(aq) and (nh4)3po4(aq)

NH4+ and NO3- because barium phosphate is insoluble 

This is what i found on google “when one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and atp is converted to adenosine diphosphate (adp). likewise, energy is also released when a phosphate is removed from adp to form adenosine monophosphate (amp).” i hope this you .

The answers is bad germs in their
