Is magnesium burning a physical change?
No, magnesium burning is a chemical change because the magnesium undergoes a chemical reaction with oxygen to form magnesium oxide. Physical changes do not alter the chemical composition of a substance, whereas chemical changes do.
Is the compression of oxygen gas a chemical reaction?
We do not generally consider the compression of oxygen as anything but a physical reaction. No and yes. Not initially, as most people would consider this to be a thermodynamic problem; no molecules are forming or being unformed. As pressure increases, though, it can trigger chemical reactions (though the compression itself is not one). As pressure becomes very high, it can become a nuclear reaction, and at extremes, revert to quark matter, and other forms of quantum phenomena.
Which of the following processes involves both physical and chemical changes?
Rusting of iron involves both physical and chemical changes. The physical change involves the formation of iron oxide on the surface of iron, while the chemical change involves the reaction of iron with oxygen in the presence of water to form iron oxide.
Hydrogen peroxide breaks down into water and oxygen explain why this is a chemical reaction what are the reactants and products in the reaction?
The breakdown of hydrogen peroxide into water and oxygen is a chemical reaction because it involves the breaking of chemical bonds and the formation of new substances. The reactants in the reaction are hydrogen peroxide (H2O2), and the products are water (H2O) and oxygen gas (O2). This reaction is catalyzed by enzymes in living organisms like catalase.
Is gasoline burning a physical property?
Gasoline burning is a chemical property because it involves a chemical reaction where gasoline is combined with oxygen to produce heat, light, and exhaust gases. This process results in a change in the chemical composition of the gasoline.
Reaction with oxygen is a physical or a chemical change?
Oxidation is a chemical process.
If you say 'oxygen gas supports combustion' are you talking about a chemical or physical reaction?
Combustion is a hemical reaction.
Is flammability a physical property or a chemical property?
chemical property.Flammability is a chemical property (reaction with oxygen=oxydation).
Is combining hydrogen and oxygen to make water physical?
This is a chemical reaction.
Would a reaction with oxygen be a chemical or physical property?
A reaction with oxygen would generally be considered a chemical property because it involves a change in the chemical composition of the substances involved. Physical properties, on the other hand, do not involve changes in chemical composition.
Is heating mercuric oxide a physical or chemical change?
This is a chemical reaction; oxygen is released.
Is rusting a 'physical' reaction?
Yes, rusting is a chemical reaction in which iron reacts with oxygen in the presence of water to form iron oxide (rust). It is not solely a physical reaction, as it involves the breaking and formation of chemical bonds between the iron and oxygen atoms.
Why is a burning candel a chemical change and not a physical changes?
Burning is a chemical reaction with oxygen (oxidation).
What is a reacts with oxygen is it physical or chemical?
Anything chemical , including oxygen, reacting with anything else is a CHEMICAL change. So Rust, is an oxide of iron. It has been formed by the chemical change of iron reacting with oxygen.
Is an ability to burn physical or chemical?
It is a chemical property, as it involves a chemical change.
Is magnesium plus oxygen a chemical or physical change?
The reaction between magnesium and oxygen to form magnesium oxide is a chemical change. This is because new substances with different properties are formed during the reaction.
If Iron and oxygen form rust is it a chemical or physical reaction?
The formation of rust from iron and oxygen is a chemical reaction. This is because the iron reacts with oxygen in the air to form a new compound, iron oxide (rust), which has different chemical properties from the original iron.
