If two covalently bonded atoms are identical, the bond is

nonpolar covalent bond

Explanation:
A covalent bond occurs when two atoms share electrons between them so that they both become stable.
A nonpolar covalent bond means that the two atoms involved in the bond are identical and share the same number of electrons equally.

Hope this helps :)

Only one reactant yields 2 or more products. meaning you will only have 1 product and it will break down into 2 or more products. eg. h2o -> h2 + o2
