Answer: Inhibitor
Explanation: Chemicals that slow down the reaction are called inhibitors.
Statement B is true because atoms are single particles that come together to form compounds and molecules.
Answer:
A) Very stable.
Explanation:
A valence electron ring takes up to 8 valence electrons. If it has full rings, it is stable.
Answer:
hydrogen bonds are very weak and can only occur when polar covalent bonds are present
Explanation:
Hydrogen bonds are weak intermolecular interactions that occur when hydrogen is covalently bonded to a highly electronegative atom.
Owing to the difference in electro negativity between hydrogen and the highly electronegative atom, the bond is a polar covalent bond.
This hydrogen bond is a weak bond but accounts for properties such as high melting and boiling points of small molecules such as water and ammonia.
