what you have to do is to multiply the given grams with the ratio of grams of that certain element in it's full compound in order to isolate the compound and get the element.

Hydrogen bonds are a strong attractive force, since they are less stronger than ionic bonds.
It’s decomposition. The compound is being broken apart into two different things aka decomposing.
