Question
A teacher tells students to describe physical properties of 10 mL of vinegar and 10 mL of milk. When the students finish listing the physical properties in their science notebooks, the teacher pours the vinegar and milk into the same beaker. The students are surprised to see a white solid substance form within the beaker as the two substances are combined. 13 What occurs within the beaker as the teacher mixes the vinegar and milk?
