No, powdering sugar is a reversible change because the sugar can be easily changed back to its original form by adding water and heating it.
IRREVERSIBLE
no
Irreversible examples: Burning a piece of paper, baking a cake, digesting food, rusting of iron, breaking a glass. Reversible examples: Melting ice into water, boiling water into steam, freezing water into ice, dissolving sugar in water, compressing a gas into a liquid.
Everything, no matter what it is, will go through an irreversible change if caught on fire or melted. It doesn't matter how slowly the change is. When you burn or melt something down, the change is always permanent.
Yes, it is a chemical reaction because imply the partial thermal decomposition of sugar.
