When a pure solid Z sample it a covalent compound is heated continually for 11 minutes it will undergo disintegration leaving the bonds intact.
<h3>What is a covalent compound?</h3>
A covalent compound is a compound that is made up of molecules which share one or more pairs of valence electrons and are bonded together by a covalent bond.
One of the major factors that affect compounds with covalent bonds is temperature.
The increase in temperature during heating leads to the separation of the atoms from each other but leaving the bonds intact.
