What is a chemical change and give example?
A chemical change is a process that results in the formation of new substances with different chemical properties. For example, when iron rusts, it undergoes a chemical change as it reacts with oxygen to form iron oxide, a new substance with different properties than pure iron.
When wires are bent is that an example of chemical change?
No, bending wires is a physical change, not a chemical change. Chemical changes involve the formation of new substances with different chemical properties, while bending wires only alters their shape and does not change their chemical composition.
How are a chemical and physical change different?
In a physical change, the substance is still the same substance after the change. But in a chemical change, the substance became another substance with different properties from the original substance.Physical change is changing the appearance of something. Example - Rip a piece of paper - physical change. Burn gasoline - chemical change.
Which is an example of an chemical change?
an example of a chemical change is burning. there are, of course, many others.
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 the formation of a solid a chemical change?
Yes, if it occurs as the result of a chemical reaction. For example, if two clear colorless solutions form a white precipitate (solid) when mixed, that would be an example of a chemical change. The formation of a solid from freezing is a physical change.
Name an example of a chemical change?
Burning is a chemical change.
What is rust an example of a physical or chemical change?
Chemical change.
Which activity is an example of a chemical change?
Cooking is for example a chemical change.
Is rusting an example of physical or chemical change?
Rusting is the oxidation of a metal and is an example of a chemical change.
What is a change that forms a different kind matter?
A chemical change is a transformation where substances are converted into different kinds of matter with new properties. This involves the rearrangement of atoms and the formation of new chemical bonds. An example of this is when hydrogen and oxygen combine to form water.
What is a chemical change example of moldy cheese?
A chemical change example of moldy cheese is the breakdown of proteins and fats in the cheese by enzymes produced by mold. This leads to the production of new compounds with different chemical compositions, such as organic acids and flavorful compounds.
