A. formation of a solid from two liquids

Explanation:

A chemical change is the process that forms new products by formation of new bonds and group transfer between substrates. Any change in physical features of chemicals with no formation of new products is termed as physical change. Transition of phases of matter, change in surface area and volume are the physical changes. Formation of a solid (a new product) from two liquids represents chemical change.
