This cannot be answered without knowing how much oxygen there is. ===== Each molecule of oxygen consists of two atoms of oxygen.
Molecules have to be stuck together, or they would not be molecules. Molecules are bonded to one another because of electrons. Without those bonds, they would be individual atoms.
Ionic and metallic substances both do not have covalent bonds!
Because, it has no crosslinks therefore its molecules move more freely. On the other hand, some other polymers, such as Bakelite, are crosslinked and you cannot turn then into a liquid without breaking the covalent bond.

Molecules are made out of atoms, without atoms there are no molecules. Charged molecules (ions) will form compounds as elements do, by combining in whole-number ratios with the ions of other elements and compounds.
Because covalent bonds are between elements without metallic properties, and in order for a bond to conduct electricity, the bond has to include two metals, AKA a metallic bond.
Most minerals are compounds, which contain several different elements. The periodic table consists only of elements. And all minerals, without exception, are composed of the elements which are found on the periodic table of elements.

Because sodium chloride form giant lattices without a limit between molecules.
Atoms. Some atoms can not exist without another atom/s to stabilise it and form a molecule For example, the O2 (oxygen) molecule consists of two O (oxygen) atoms. The H2O (water) molecule consists of two H (hydrogen) atoms and one O (oxygen) atom.

Ribozymes are RNA molecules that can act as enzymes; that is, catalyze covalent changes in the structure of substrates (most of which are also RNA molecules). Simple answer without Ribozymes we have no information or tools to allow us create blueprints for DNA or any structure of life.

The short answer, without too much research or effort on my part, is that hydrogen bonds are weaker. The are due to the attraction of hydrogen to other elements (such as oxygen) that have lone pairs swimming around. Covalent bonds are due to electronic effects, and as such are stronger.
Glucose is a compound made up of the elements carbon, oxygen and hydrogen. Glucose solution in water is a mixture of water molecules and glucose molecules. Mixing them doesn't produce any new substance, and you can separate them without creating any new molecules.
