Unconsciousness after a severe head injury is an automatic 911 call "true"

Explanation:

In serious head injuries that abrupt stop can basically shut the brain down so fast that the patient falls unconscious. That is an automatic 911 call, even if they begin to recover afterwards. It's still a 911 call because that type of traumatic injury is bad enough that it could develop into a life threatening issue. A concussion occurs when the brain abruptly strikes the inside of the skull. In serious injuries, this rapid movement can basically shut the brain down so fast that the patient falls unconscious.

The element that is mostly likely to form covalent   bonds with Sulfur  is   Oxygen ( O)

Explanation

  Covalent bond is bond that involves the sharing of  electrons  pairs  between atoms.   Mostly  a covalent bond is formed when  two non metals  react. for example  when S  react with O2 to form SO2  a covalent  bond is formed since each oxygen atom share two  valence electrons with sulfur.Helium is inert therefore it  does not react with Sulfur.Magnesium and Zinc are metal and react with sulfur to form an ionic bond.
