Answer: Formation of hydrogen iodide will occur.
Explanation:
When molecule of hydrogen gas 
and molecule of iodine gas 
collide with proper orientation and with sufficient amount of energy. This collision of the two different molecules of gases will result in the formation of hydrogen iodide.
The balanced chemical equation of the reaction will written as:
C. Elements combine to form compounds in organisms and nonliving substances
Explanation:
Elements combine to form compounds in both living and non-living organisms.
- Elements are distinct substances that cannot be split-up into simpler substances.
- Elements are made up of only one kind of atoms
- Elements are pure substances.

Answer:
According to the Safety Data Sheet (SDS), the major harzard of concentrated HCl is that it may cause severe burns to skin, eyes and mucous membranes.
Explanation:
The SDS also informs that:
Most Important Hazards:
- May cause severe burns to skin, eyes and mucous membranes.
- Steam produced is irritating.
- Pollution of rivers and water bodies by changing the pH. Affects flora and fauna that comes in contact with acid.
Product Effects:
- If in direct contact with eyes will cause serious burns and vision loss.
Adverse effects to human health:
- Inhalation causes severe respiratory tract irritation. May cause pulmonary edema. The contact with the skin causes burns, which can lead to dermatitis. Prolonged contact of acid leads to visual damage to vision loss. If swallowed, may cause burns to the mucous membranes of the mouth and digestive system.
Environmental Effects:
- Affects rivers and streams by changing the pH of the water. May contaminate the soil. Vapors may temporarily affect air quality.
Physical and chemical hazards:
- Reacts with metals such as; iron, aluminum, zinc, magnesium, among others, forming hydrogen, which mixed with air may cause explosion and air displacement upon ignition under specific.
It would be atomic masses of the same atoms, and that atoms will be isotopes.
