For the First part I believe elements naturally exist in nature and compounds are formed so elements can be more stable. (I think this is right I’m not 100% but I’m close)
For the second part the two main types of bonds are ionic and covalent. Ionic bonds involve the transfer of electrons and covalent bonds involve the sharing of electrons. (I’m 100% on this one)
Answer:
Hydrogen bonding
Step-by-step explanation:
The O-H bonds in water are highly polar.
There is an especially strong type of dipole-dipole attraction between the partially positive H atom in one molecule and the partially negative O atom on a nearby molecule.
We call this type of intermolecular force hydrogen bonding.
The strong attractive forces mean that we must supply extra energy to separate the molecules from each other.
Water therefore has an <em>unusually high boiling point
.</em>
H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + 2H₂O(l)
2H⁺ + SO₄²⁻ + 2Na⁺ + 2OH⁻ → 2Na⁺ + SO₄²⁻ + 2H₂O
H⁺ + OH⁻ → H₂O (the net ionic equation)
