When Ba²⁺ and PO₄³⁻ reacts Barium phosphate is formed. the correct formula for Barium Phosphate is Ba₃(PO₄)₂
Ba²⁺ and PO₄³⁻ are charged so they are ions,Ba²⁺ is a cation because it is positively charged and PO₄³⁻ is an anion because it is negatively charged, when they reacts negative and positive charge attracts each other and a neutral salt is formed which is barium phosphate (Ba₃(PO₄)₂).
La materia puede encontrarse en diferentes estados dentro de nuestro planeta: líquido, sólido y gaseoso. Fuera de la Tierra existe un cuarto estado, conocido como plasma, que abunda en lugares como el Sol y las estrellas.
Answer:
The mole is the SI unit for amount of a substance.
