Yes. Tarnished silver is caused by the reaction of the silver with oxygen.
A chemical reaction (change) results in a change in chemical properties.
its a chemical change
In a chemical change, the end result is the formation of new substances with different chemical properties from the original substances. Bonds between atoms are broken and new bonds are formed, resulting in a chemical transformation.
Chemical change occurs
The new and different substances formed as a result of a chemical change (reaction) are the products of the reaction.
The loud pop indicates a chemical change. The glowing splint caused a reaction that produced a gas (likely oxygen or hydrogen) leading to the noise. This transformation is a result of a chemical reaction and not just a physical change.
Nope. (Well, the chemical reaction of the high explosives in an A- or H-bomb warhead result in high pressure that then results in a nuclear change (BOOM), but that's a side-effect, not a direct result of the chemical change.)
It is a chemical change.
Depending on the chemical change, sometimes color change, or appearance of bubbles.
Fizzing is the result of a chemical change - a chemical reaction with gas releasing.
Neither. Body heat is a result of chemical changes, but it's not itself a chemical change.
Chemical. Something else is created as a result, and the composition does change, making it a chemical change.
