Phosphoric acid and barium hydroxide solutions mix to form water and solid barium phosphate. Write the word equation, skeletal equation, and the balanced equation for this word problem.

Answer 1

phosphoric acid plus barium hydroxide produce solid barium phosphate and water.

H3PO4 + Ba(OH)2 ==> Ba3(PO4)2 + H2O
I will leave it to you to balance.
