Hydrogen bonds are present in the following molecules: HF AND NH3 Dipole dipole inter molecular forces occurs the molecules of H2S AND H2. Hydrogen bonding is an electrostatic attraction between two polar groups that occur when hydrogen atom covalently bound with highly electronegative atoms.
This question is about stoichiometry. From the balanced equation ⇒, we see that 3 moles of water is needed to react with 1 mole of .
This means that, to fully react 3.62 moles of , we would need 3*3.62 or 10.86 moles of water. However, we only have 6.31 moles, so water is the limiting reactant.
Since 3 moles of water react with 1 mole of , 6.31 moles of water can fully react with 6.31÷3 or 2.1033 moles of .
From the balanced equation, we see that every mole of reacted gets you 2 moles of . Therefore, 2.1033 moles of would give you approximately 4.21 moles of .
