I don;t understand this question.

NaOH(aq)+H3PO4(aq)�¨Na3PO4(pq)+H2O(l)

There is no question here but see my response to your later post.

I can certainly help you understand the given equation. This is a balanced chemical equation, representing a reaction between sodium hydroxide (NaOH) and phosphoric acid (H3PO4) to produce sodium phosphate (Na3PO4) and water (H2O).

To understand the equation, let's break it down:

- NaOH(aq): This represents sodium hydroxide in an aqueous (dissolved in water) form.
- H3PO4(aq): This represents phosphoric acid in an aqueous form.
- Na3PO4(pq): This represents sodium phosphate, which is a solid (indicated by "pq").
- H2O(l): This represents water in a liquid state.

The arrow (�¨) in the middle of the equation indicates the direction of the reaction. In this case, it shows that the reactants (NaOH and H3PO4) are being transformed into the products (Na3PO4 and H2O).

The equation is balanced, meaning that the number of atoms of each element is the same on both sides of the equation. Although you mentioned not understanding the question, no specific question was asked. If you have any specific question related to the equation or any other topic, please let me know, and I'll be happy to assist you further.
