Question

14 of 30 08:30 / 40:00 which of the following is a physical change and not a chemical change? heated green copper carbonate turns it black sugar dissolving in water marble chips dissolving in acid magnesium dissolving in sulphuric acid

Explanation:

A physical change does not result in a new substance being formed. When sugar dissolves in water, it is just dispersed in the water and the sugar and water retain their chemical identities. Heating green copper carbonate forms new substances (copper oxide making it black), marble chips reacting with acid and magnesium reacting with sulfuric acid are all chemical reactions forming new substances.

Answer:

sugar dissolving in water
