@zumhlian It's somewhat pungent because some of the hydrogen gas and its interaction with compounds (e.g. those that contain sulfur) in the air.

@mrteverett thanks.
This is definitely a chemical change, since two new compounds - hydrogen and calcium hydroxide are produced when calcium is added to water.

Is calcium+water a physical change or chemical?
