Final answer:
The article titled 'How Baking Soda Reacts With Vinegar' specifically discusses a chemical change, as it involves a chemical reaction that produces new substances with different chemical properties. The article will be A. How Baking Soda Reacts With Vinegar
Step-by-step explanation:
The title of the scientific article that specifically describes a chemical change is 'How Baking Soda Reacts With Vinegar'. This article title suggests that it covers the reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid), which is a well-known chemical reaction that produces carbon dioxide gas, water, and a salt (sodium acetate). This process involves the transformation of molecules and the creation of new substances, which are hallmarks of a chemical change.
Chemical changes are distinguished from physical changes by the fact that they result in the formation of substances that have different chemical properties from the starting materials. Examples of physical changes would include changes in state, such as water boiling or ice melting, where the molecular structure remains unchanged. In contrast, chemical reactions such as combustion, rusting, and the digestion of food involve chemical changes and result in the production of substances with new chemical properties.
