Question

Помогите пожалуйста решить! Очень надо! H3PO4+Fe2O3=

Answer 1

2H3PO4+Fe2O3=2FePO4+3H2O

Answer 2

H3PO4 is the chemical formula for phosphoric acid, while Fe2O3 is the chemical formula for iron(III) oxide, also known as rust.

Phosphoric acid (H3PO4) is a strong acid that is commonly used in various industries, including food and beverage, agriculture, and pharmaceuticals. It is also used as a rust converter and as a cleaning agent for removing rust from metal surfaces. Phosphoric acid is a colorless, odorless liquid that is highly soluble in water. It is corrosive and can cause severe burns if it comes into contact with the skin or eyes.

Iron(III) oxide (Fe2O3) is a compound that occurs naturally as the mineral hematite. It is a reddish-brown solid and is commonly known as rust. Iron(III) oxide is formed when iron reacts with oxygen in the presence of moisture or water. This process is known as oxidation and is responsible for the corrosion of iron and steel. Rust is a common problem for metal objects exposed to moisture and air.

When phosphoric acid reacts with iron(III) oxide, it can form iron phosphate and water. The balanced chemical equation for this reaction is:

2 H3PO4 + 3 Fe2O3 -> 2 Fe3(PO4)2 + 3 H2O

In this reaction, two molecules of phosphoric acid react with three molecules of iron(III) oxide to produce two molecules of iron phosphate and three molecules of water.

I hope this helps! Let me know if you have any further questions.
