Number One |
From our previous class we recall that when two two different elements combine together, they form a molecule
It requires energy to make a chemical bond.

It take energy to make and break things. Water has two types of bonds which create situations where a molecule can be broken (lysis) or separated (make into a solvent). Energy and matter..an amazing thing. |
