Is turning of copper into green when exposed into environment physical or chemical change?
It is a chemical change.
Is copper turning green when exposed to the environment a chemical change?
Chemical because it is being exposed to another compound and forming a new substance
Is the baseball that strikes a roof a chemical change?
No, a baseball striking a roof is a physical change. A chemical change involves a change in the chemical composition of a substance, while a physical change only alters its physical appearance or state.
Does a physical or chemical change take place when an apple is exposed to oxygen over time with peroxide on it?
chemical
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.
Lighting a match a physical change or chemical change?
Lighting a match is a chemical change because the molecules in the matchstick undergo a chemical reaction when exposed to heat, resulting in the production of new substances like ash and smoke.
Is sodium turning black when exposed to air a chemical change?
Yes, sodium turning black when exposed to air is a chemical change. This is due to the formation of sodium oxide and sodium hydroxide when sodium reacts with oxygen and moisture in the air.
Which one is a chemical change-eletrolysis of water or sodium chloride exposed in sunlight?
The electrolysis of water is a chemical change because it breaks down water molecules into hydrogen and oxygen gas. On the other hand, sodium chloride exposed to sunlight is a physical change as it may undergo phase changes, but the chemical composition remains the same.
Is lighting a match a chemical change?
Yes, lighting a match is a chemical change because the chemicals in the match head undergo a chemical reaction when exposed to heat from friction, resulting in the release of energy in the form of light and heat.
What chemical change takes place when steel is exposed to water?
Corrosion occur if oxygen exist also.
Is white phosphorus that glows when exposed to air a chemical change or a physical change?
White phosphorus that glows when exposed to air is a chemical change. This phenomenon occurs because white phosphorus undergoes a chemical reaction with oxygen in the air to form phosphorus oxide, releasing energy in the form of light.
Is pancake batter changing into a pancake a chemical change or a physical change?
The process of pancake batter changing into a pancake is a chemical change. This is because the ingredients in the batter undergo a chemical reaction when exposed to heat, leading to the formation of new compounds with different properties.
