@AtDeathsDoor98 The hydrogen gas will burn. If this is done after the calcium begins floating [after it reacts for a while it shrinks in size as some if it is reacted [becoming insoluble calcium hydroxide that is temporarily suspended, but will settle out and sink to the bottom]] the calcium can also burn and add an orange color to the flame. The hydrogen gas can also be trapped and burned separately.
I have a sort of funny question you could say...so if you decided to manufacture cookware with calcium metal instead of aluminum in order for dietary benefits ,it would be a bad idea based on this reaction ...correct?
@xxbignolanxx The smell is most likely from the H2 although I wouldn't classify it as toxic- certainly breathing just H2 is a problem, but that's true for any gas that is not air or oxygen. Now H2 is very reactive but that is different.
@apard7 Your body needs calcium, but not in this form. The reaction of calcium with water forms calcium hydroxide (Ca(OH)2) which is a very basic and caustic substance also known as lime water [or limewater]. Plus as a general rule, never drink out of lab glassware.
calcium metal its self burns forming CaO

thanks, really helpful for my chemistry exam :)

What would happen if you held a flame near the top where the bubbles pop and the gas is given off?

when the reaction happenes... id water vapour given off?
PLZ REPLY ASAP- NEED FOR A LAB REPORT

@MegaMusicLover22 No, I say it in the video at 0:39.

It is quite exothermic

@jokerc110 Yes a bad idea, not only because of this reaction, but also because the by-product is very basic [alkaline].

I did this experiment yesterday and came a lots of bubbles, and it smells bad

@kelvin1651 Maybe because it gives off hydrogen gas which is very toxic?

is this an exothermic reaction

@khashya786786 Yes, I don't know the specific heat of the reaction, but it shouldn't be too hard for me to look up tomorrow.
