which is evidence that a chemical reaction has likely occurred?\no a liquid slowly losing volume\no the formation of a precipitate\no boiling water releasing steam\no a change in the shape of a solid
Answer
Brief Explanations:
A chemical reaction results in the formation of new substances. Formation of a precipitate indicates a new solid - substance is formed from a chemical reaction in a solution. A liquid losing volume can be due to evaporation (physical change), boiling water releasing steam is a phase - change (physical change), and a change in the shape of a solid is a physical deformation.
Answer:
the formation of a precipitate
