Phosphoric acid is added to many popular beverages to give them a tart flavor. the formula of phosphoric acid is 1. h2po4. 2. h3po4. 3. hpo4. 4. h4po

Phosphoric acid is composed of phosphorous, hydrogen and oxygen. It is a weak triprotic acid, i.e. it has three ionizable protons.

The formula for phosphoric acid is H3PO4. Its dissociation can be represented by the following equations:

H3PO4 ↔ H2PO4⁻ + H⁺

H2PO4- ↔ HPO4²⁻ + H⁺

HPO4²⁻ ↔ PO4³⁻ + H⁺

Ans: H3PO4

if you mean hydrogen and oxygen then water is the product

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
