Is mostly likely a chemical change salt dissolving in water or a match burning?
A match burning is a chemical change. Salt dissolving in water is a physical change.
What is an example of a chemical change wood burning glass breaking water freezing?
The chemical change is the burning wood because the products, carbon dioxide, water, ash, and soot, have different physical and chemical properties. The other changes are physical changes because the physical and chemical properties of the substances did not change.
Is a log burning a chemical or physical change?
Chemical change, because it is irreversible. The chemical composition of the substance actually changes. A physical change is a change of state, like water to ice. There, H20 is still H20.
What answer of burning paper physical change o chemical change?
Chemical change. Burning anything will create a chemical change. Burning involves taking the object/substance being burnt + oxygen to produce water and carbon dioxide.
Is burning a match a physical change?
Yes, burning a match is considered a chemical change because it involves a chemical reaction that changes the composition of the matchstick and produces new substances like ash, carbon dioxide, and water vapor. This is different from physical changes, which do not alter the chemical composition of a substance.
How does chemical change happens in photosynthesis?
it happens when •A physical change is reversible, a chemical change is not.•the freezing of water would be a physical change because it can be reversed, whereas the burning of wood is a chemical change - you can't.
Is sugar burning in a pan chemical or physical change?
Burning Sugar is a chemical change. Burning or oxidization is always a chemical change. The process takes in Oxygen and Sugar and outputs different compounds including water, carbon dioxide, carbon monoxide, and other carbon residue. Explanation 2: Chemical changes are changes in what things are made out of. Physical changes are like ice melting ice and liquid water are still water one is a solid but the other is liquid. steam is a gas but is still water. these changes do not change what water is.
Is burning sugar a physical change?
Burning or combustion is always a chemical change sugar on burning produce carbon dioxide and water vapours which can neither be again change in sugar, while a physical change is always reversible.
Is burning breakfast physical or chemical change?
Burning breakfast involves a chemical change because the chemical composition of the food is altered as it reacts with oxygen to form new substances like carbon dioxide and water vapor.
Burning toast physical or chemical change?
Burning toast is a CHEMICAL change. A physical change is reversable-for example, you can freeze water into a cube and then defrost and reconvert to water. Burning is always a chemical change. In order for something to burn, some of the original substance must be lost and therefore cannot be turned back into its original form
How is an chemical change differs from a physical change?
Physical change is the change in which only physical properties changes ,like color, hardness, density etc. Chemical changes affect the composition as well as chemical properties of matter and result in formation of new substance. Examples of chemical changes are : Burning of coal Burning of Paper Electrolysis of water
Is burning of paper is one example of physical change?
Burning of paper is actually an example of a chemical change, not a physical change. During burning, the chemical composition of the paper changes as it reacts with oxygen to produce new substances like ash, water vapor, and carbon dioxide.
