What is rusting short answer?

Rusting is oxidation of iron or iron objects. It takes place in the presence of air and moisture. It is a slow process. It is a red-orange colored iron oxide which is formed by the oxidation of iron in presence of oxygen and moisture or water.

What is called rusting Class 7?

When an iron object is left in damp air (or water) for a considerable time, it gets covered with a red-brown flaky substance called rust. This is called rusting of iron.

What is rusting Class 5?

Rust is an iron oxide formed by a reaction of iron and oxygen where water or air moisture is present. …

What is rusting in basic science?

Basic Science Week3 Topic: Rusting Introduction When iron is exposed to air and moisture, its surface gradually corrodes and converts into a brown mass. This brown mass is called rust and this phenomenon is known as rusting. The corrosion of metals results from the combined action of atmospheric oxygen and water.

What is rusting Class 7 long answer?

During the rusting of iron, it combines with the oxygen in the presence of water (moisture) to form a new compound ‘iron oxide’. This iron oxide is a rust. It is a permanent change which cannot be reversed back. So, rusting of iron is a chemical change.

What is a Rust Class 10?

Rust is the general name for Iron oxide, when we leave iron or it’s alloys in open for a long time, oxygen and hydrogen in the air reacts with the metal to form hydrated oxide. Rusting occurs in the presence of water or moist air. It’s an example of electrochemical reaction and corrosion.

What is rusting class 10th?

Answer: Rust is a chemical reaction (oxidation) of iron that occurs over a period of time as the bare metal surface comes in contact with oxygen present in the air or water. Rust “eats” away the metal, rendering it weak and fragile. Avoid contact with water or moisture.

What is rusting Class 7 Brainly?

Answer: Rusting occurs when iron is exposed to oxygen in air and water or water vapor. The process of rust formation in presence of oxygen and water or water vapor is called rusting.

What is corrosion 10th?

Corrosion is the deterioration of a metal as a result of chemical reactions between it and the surrounding environment. Metals are attacked by substances in surroundings like moisture and acids: Silver – it reacts with sulphur in the air to form silver sulphide and turns black.

What is rust in chemistry class 10?

What is rusting for Class 8?

Rusting is a process in which iron metal reacts with moist air (water + oxygen) present in the atmosphere to form iron oxide, Fe2O3, which is reddish brown in colour. Rusting of iron leads to very heavy damage to the substance.

What is rusting for Class 10?
