c)What happens when dilute hydrochloric acid is added to A and B?

Answer 1

Answer:

mixture is made when you combine matter in a way where the components can be separated again. A compound results from a chemical reaction between components, forming a new substance. For example, you can combine iron filings with sulfur to form a mixture. All it takes is a magnet to separate the iron from the sulfur. On the other hand, if you heat the iron and sulfur, you form iron sulfide, which is a compound.
