which of the following signs of a chemical reaction are observed in the reaction of potassium with water?\nprecipitate formed\ntemperature change\nsmell produced\ngas produced\ncolor change\ndone
Answer
Brief Explanations:
When potassium reacts with water, it is a highly exothermic reaction, releasing heat (temperature change). Hydrogen gas is produced during the reaction. There is no precipitate formed, no distinct smell produced in a common - sense way for this reaction, and no color change in the solution itself (the flame may have a color during the reaction but that's not a color - change of the solution).
Answer:
temperature change, gas produced
