The hydrogen bond that exist in the ammonia molecule is the reason why it shows higher boiling point compare to the other hydrides. Hydrogen bond occur in ammonia because ammonia is one of the most electronegative elements.

When, it translated, it forms into "Protein"
[ We used all 6 words, but in sequence, with proper functioning/place ]

It important to test the crucible for cracks before heating it because it can break while performing the chemical reaction.
The crucible and the lid should be inspected to check for the before heating it to prevent the breaking while performing the reactions. if there are some breaks in the crucible then if we heat the crucible it can lead to breaking of the whole crucible and the material from the crucible to come out and it will come in contact with the lid.
The crucible plays a important role while preforming the reactions, so. it important to check the cracks of the crucible before the heating of the crucible.
