Explanation

The bond formed between water molecules (H2O) is a hydrogen bond.

The bond within the water molecule itself is a covalent bond

Explanation

• A hydrogen bond is a type of intermolecular force that arises between a highly electronegative atom (such as oxygen, nitrogen, or fluorine).
• A hydrogen atom that is bonded to a highly electronegative atom.
• This interaction is typically weak compared to covalent bonds.
• But it is strong enough to influence the physical and chemical properties of molecules.

Explanation

• hydrogen gas can not use as fuel
• ***
• "AS " is best to keep the meaning of the original sentence
• ****
• TWO REASONS WHY WE USE THE "AS" PREPOSITION IN THE ABOVE SENTENCE

• 1: We use as with a noun to refer to the role or purpose of a person or thing:

Explanation

• The lightest gas used for filling party and advertisement balloons is hydrogen.
• However, due to its flammability, helium is more commonly used despite being slightly heavier, because it is safe and non-reactive.
