Is iron rusts a physical or a chemical change?
Rusting of iron is a chemical change because it involves a chemical reaction between iron, oxygen, and water to form iron oxide (rust). This reaction leads to the formation of a new substance with different properties from the original iron.
What is the difference between lava and fire?
Lava is molten rock that flows from a volcano, while fire is a chemical reaction that produces heat and light. Lava comes from below the Earth's surface, while fire typically originates from the combustion of materials.
When oxygen gas supports combustion is it called physical or chemical change?
When oxygen gas supports combustion, it is considered a chemical change. This is because a new substance is formed through the reaction between oxygen and the fuel, resulting in the release of heat and light.
When a substance burns what does it do with oxygen?
When a substance burns, it undergoes a chemical reaction with oxygen called combustion. During this process, the substance reacts with oxygen to produce heat and light energy, along with new chemical compounds like carbon dioxide and water vapor.
What is the rapid burning of fuels that takes place in engines is called?
The reaction between oxygen and another substance is called oxidation, such as the formation of rust. The rapid oxidation of fuel is called combustion.
What is the burning of substance called?
Burning is an oxidation reaction - a reaction with oxygen.
What is the name of the process used to describe the reaction between a chemical substance and oxygen?
oxidation.... I think
What is the chemical substance that combine with oxygen?
Many chemical elements combine with oxygen; the reaction with oxygen is called oxydation.
What is a chemical reaction between a substance and air called?
A Combustion reaction. It usually happens between a gas and oxygen. The products are CO2 and H2O.
What is the chemical reaction between magnesium and oxygen called?
The chemical reaction between magnesium and oxygen is called magnesium oxide formation. This reaction occurs when magnesium metal reacts with oxygen gas to produce magnesium oxide, which is a white powdery substance. The chemical equation for this reaction is 2Mg + O2 -> 2MgO.
Why can't something burn without oxygen?
Fire is a chemical reaction between oxygen and some flammable substance. Without oxygen you are missing one of the ingredients.
Is fire a basic element?
It is in classical mythology, but not in reality. In reality fire is not even a substance but a chemical reaction between oxygen and some flammable substance.
What type of reaction is it when iron combines with oxygen to form a more complex substance?
The reaction between iron and oxygen to form a more complex substance is a chemical reaction known as oxidation. In this reaction, iron undergoes oxidation, gaining oxygen atoms to form iron oxide.
When magnesium combine with oxygen to form magnesium oxide what type of reaction is form?
The reaction between magnesium and oxygen to form magnesium oxide is a chemical reaction called a combustion reaction. In this type of reaction, a substance (such as magnesium) reacts with oxygen to produce heat and light.
Is burning woo sublimation?
Burning is a chemical reaction between a substance and oxygen. Sublimation is a type of physical state change produced by changes in temperature and/or pressure; it is not a chemical reaction. Sublimation is not the same as combustion.
What is A reaction between a substance and oxygen?
and nitrogen causes h2o
When heating a substance what happens?
Heating a substance can result in a chemical reaction, which usually results in a simple combustion reaction. This is because Oxygen, or O2, is added to the substance, which can dramatically alter the substance.
