Hair being bleached with hydrogen peroxide is a chemical change, not a chemical property. Chemical properties describe how a substance reacts with other substances to form new substances, while a chemical change involves the actual rearrangement of atoms and molecules in a substance. In this case, hydrogen peroxide is breaking down the pigment molecules in the hair, causing it to change color.
What else can I help you with?
Is hydrogen a chemical or physical property?
Hydrogen is a chemical property because it is a pure substance and it cannot be broken down into simpler substances by physical means. It is the simplest and most abundant chemical element in the universe.
What is a chemical property of the element hydrogen?
One chemical property of hydrogen is its ability to react with oxygen to form water. Hydrogen also exhibits the property of being highly flammable when exposed to air or an oxygen-containing atmosphere.
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.
Is reacting with oxygen a physical property of hydrogen?
No, reacting with oxygen is a chemical property, not a physical property, of hydrogen. Physical properties are characteristics that can be observed without changing the substance's chemical composition, such as density or color. Chemical properties, on the other hand, describe how a substance can change or react to form new substances.
Is does not react with hydrogen a physical or chemical change?
This is a chemical property of an element. It indicates how an element interacts with other substances. In this case, the element does not undergo a chemical change when exposed to hydrogen.
Is hydrogen chemical or physical property?
Hydrogen is neither a chemical or physical property...it is a chemical element.
Is hydrogen a chemical or physical property?
Hydrogen is a chemical property because it is a pure substance and it cannot be broken down into simpler substances by physical means. It is the simplest and most abundant chemical element in the universe.
When an object reacts with acid to form hydrogen is it a chemical or physical property?
It is a Chemical property.
When sodium metal in water produces hydrogen gas is it a physical property or a chemical property?
The reaction of sodium metal with water to produce hydrogen gas is a chemical property. This is because a new substance (hydrogen gas) is formed as a result of a chemical reaction between sodium and water.
Is it a chemical change physical change chemical property or physical property when hydrogen chloride is a gas at room temperature.?
The observation that hydrogen chloride is a gas at room temperature is a PHYSICAL property.
Is oxidation chemical property?
Yes. oxidation is chemical property. It includes addition of oxygen or removal of hydrogen
Is burning hydrogen a chemical property?
Burning hydrogen is a chemical change rather than a chemical property. A chemical change involves the formation of new substances with different chemical compositions, as in the reaction between hydrogen and oxygen to form water. A chemical property, on the other hand, describes how a substance can undergo a chemical change.
What is a chemical property of the element hydrogen?
One chemical property of hydrogen is its ability to react with oxygen to form water. Hydrogen also exhibits the property of being highly flammable when exposed to air or an oxygen-containing atmosphere.
What is the chemical property of a glow stick how do you compare chemical properties?
Glow sticks produce an chemical property called chemiluminescence. This means that chemical reactions produce light. Glow sticks are made of three chemicals: diphenyl oxalate, hydrogen peroxide, and a fluorescent dye. The hydrogen peroxide is contained in a glass vial suspended in the diphenyl oxalate/dye solution, which is inside the glow stick itself. When you bend the plastic glow stick far enough, it breaks the glass vial inside, which releases the hydrogen peroxide, causing it to mix with the diphenyl oxalate and dye. When this happens, a chemical reaction occurs that breaks the diphenyl oxalate into two molecules of phenol and a peroxyacid ester. The peroxyacid ester decomposes into carbon dioxide and releases energy in the process. The energy is absorbs by the fluorescent dye, which is then re-emitted as a photon (light).
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.
Is something that displaces hydrogen from water a chemical or physical property?
it is a physical property(electricity).
What chemical property is shown when hydrogen maeks a slpint ignite?
I think you mean oxygen. However, hydrogen itself might ignite if heated enough by the splint. The chemical property is, anyway, either carbon or hydrogen's affinity with oxygen.
