a solid is placed in a solution. which observation most likely indicates that a chemical reaction has occurred?\nthe size of the solid has rapidly decreased.\nthe color of the solution has not changed.\nthe solid has bubbles forming on its surface.\nthe temperature of the solution stays the same.
Answer
Brief Explanations:
A chemical reaction often produces a gas as a product, which appears as bubbles. Decrease in solid size could be due to physical dissolution. No - color change and constant temperature don't strongly indicate a chemical reaction.
Answer:
The solid has bubbles forming on its surface.
