Evidence of chemical reaction is Releasing of gasFormation of precipitationChange in temperatureAll of the above

When does precipitation occur?

Long-term temperature changes, over decades or centuriesChanges in atmospheric composition, from mostly hydrogen to mostly nitrogenPrecipitation resulting from circulation in the atmosphereTemporary variations in temperatureStorms (short-term precipitation and temperature change)
