Two chemicals at room temperature (about 23°c) were combined in a flask. at first, there were bubbles. then, white flakes appeared at the bottom of the flask. after five minutes, the temperature of the solution was 33°c. a portion of the solution was used to measure its density and boiling point, which were determined to be 4.5 g/l and 82°c, respectively.
did a physical or chemical change occur?
how do you know it is not the other kind of change? provide at least three points of evidence that support your claim.
