25: Which observation is consistent with a chemical reaction occurring? Why? Solid copper deposits on a piece of aluminum foil when the foil is placed in a blue copper nitrate solution. The blue color of the solution fades. Liquid ethyl alcohol turns into a solid when placed in a low-temperature freezer A white precipitate forms when solution of barium nitrate and sodium sulfate are mixed A mixture of sugar and water bubbles when yeast are added. After several days the sugar is gone and ethyl alcobol is found in the water
