When methanol is burned and leaves a residue a physical or chemical change?
When methanol burns and leaves a residue, it undergoes a chemical change. The burning of methanol involves a combustion reaction, where the methanol is reacting with oxygen to form new substances, such as carbon dioxide and water. The residue left behind is a result of this chemical reaction.
Is charring a marshmallow a chemical or physical change?
Charring a marshmallow is a chemical change because the heat causes the sugars in the marshmallow to break down and react with oxygen in the air, producing new substances. This results in a change in the chemical composition of the marshmallow.
Is the elements ability to react oxygen a physical property?
No, the ability of an element to react with oxygen is a chemical property, not a physical property. Physical properties are characteristics that can be observed without changing the substance's chemical composition, while chemical properties describe how a substance interacts with other substances.
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.
Hydrogen can explode when ignited in air is physical property?
Yes, the fact that hydrogen can explode when ignited in air is a chemical property. It is a characteristic of hydrogen's reactivity with oxygen that results in a combustion reaction, producing energy in the form of heat and light.
If leaves producing oxygen a chemical or physical change?
That would be a chemical change.
Is a sugars and oxygen in the muscles producing lactic acid physical or chemical change?
This is a chemical change.
Do trees stop producing oxygen as they age?
No,They are always producing Oxygen.No. The more leaves the more oxygen.
Plants changing carbon dioxide and water into sugar and oxygen a physical or chemical change?
Yes it is chemical because the sun is producing food by causing chemicals and substances
Is iron and oxygen from rust chemical or physical?
Physical
When oxygen is liquefied is it a physical or chemical change?
Physical because it is still Oxygen. A chemical change results in a chemical equation and thus a new substance. No new substance = no chemical change. Liquefaction is a physical property.
Is burning of branches physical change?
No, it's a chemical reaction with O2.In physical changes the chemical formula remains the same; like ice (H2O) and water (H2O). Burning wood is something like cellulose + O2 --> CO2 + H2O
Is leaves produce oxygen a physical or a chemical change?
Its a chemical change. Leaves breathe in carbon dioxide. They use it to carry out the process of photosynthesis that is preparation of food for growth. Chemical changes involving salts, water, carbon dioxide take place in the presence of sunlight that results in the liberation of oxygen into the atmosphere. At night however in the absence of sunlight it breathes in oxygen to prepare food, since photosynthesis is not possible due to absence of sunlight.
Is reacts with oxygen a physical property or a chemical property?
If something reacts with oxygen that is a description of a chemical property.
Reaction with oxygen is a physical or a chemical change?
Oxidation is a chemical process.
