Is burning alcohol in oxygen a physical or chemical change?
Burning alcohol in oxygen is a chemical change because it involves a chemical reaction that produces new substances with different properties. The alcohol (ethanol) reacts with oxygen to form carbon dioxide and water vapor, which are completely different from the original alcohol molecules.
Is breaking water up into oxygen and a hydrogen gas a physical or chemical change?
Breaking water into the component parts of hydrogen and oxygen is a CHEMICAL change.
Is Oxygen and hydrogen combining to form water physical or chemical change?
This is a chemical change.
What is the equation for the chemical change that produces water from two hydrogen molecules and one oxygen molecule?
The balanced chemical equation for the formation of water from two hydrogen molecules and one oxygen molecule is: 2H₂ + O₂ → 2H₂O.
Is decomposing water physical or chemical change?
Chemical change; bonds are broken when water decomposes into hydrogen and oxygen.
What is a sentence using hydrogen oxygen chemical change compound water?
There are many sentences that could include these terms. One such sentence is the following: The process by which hydrogen and oxygen convert to water is a chemical change. Also: water is formed in a chemical change involving hydrogen and oxygen.
Is a change that produces a new substance is a chemical change?
False. This is a chemical change. A physical change is, for example, when Ice melts into water. It is the same element but it is in a different form. A chemical change is, for example, when two hydrogen atoms and an oxygen atom come together to form a water molecule, thereby producing a new substance.
Is iron nail rusts in water a chemical change or a physical change?
Chemical change, oxygen binds with iron.
What is the name of chemical reaction in plants that produces glucose?
Photosynthesis uses CO2, water, and sunlight to produce glucose, oxygen, and water.
Is sulfur combined with oxygen produces sulfur dioxide a physical change?
This is a chemical change because there is a molecular change in the composition. A physical change results when the size, shape, phase, texture etc. of a substance changes. Liquid water heated to water vapor is a physical change.
Is separating water into oxygen and hydrogen an example of a change?
Yes, separating water into oxygen and hydrogen is an example of a chemical change. It involves breaking the bonds between the hydrogen and oxygen atoms in water molecules, resulting in the formation of new substances with different properties (oxygen and hydrogen gas).
Example of physical change and a chemical change?
when water changes to water vapour by heating is an example of physical change. when water is divided into oxygen and hydrogen by passing electricity is an example of chemical change.
