Hydrogen bonding is an intermolecular force that operates between molecules where hydrogen is bound to a strongly electronegative element such as fluorine or nirogen. Hydrogen sulfide has some (little) degree...
1 Answers 1 viewsHydrogen is a strong bond, therefore, it produces a lower evaporation rate and thus, a lower vapor pressure.
1 Answers 1 viewsmake matter more stable. Whenever you are trying to changes phases it takes energy to overcome those strong inter molecular forces. In turn the melting point is raised to...
1 Answers 1 viewsConsider water, $OH_2$. This is a very low molecular weight material that has quite an elevated normal boiling point. The strength and persistence of intermolecular hydrogen bonding is responsible for...
1 Answers 1 viewsHydrogen bonding occurs where HYDROGEN is bound to a strongly electronegative element, i.e. hydrogen is bound to fluorine, nitrogen, or oxygen. In $"fluoroform"$, the hydrogen is bound to carbon not...
1 Answers 1 views$H_2S$, and $PH_3$ are real molecules, and for the phosphine, hydrogen-bonding DOES not occur. And for the sulfide, hydrogen-bonding is only marginal. Phosphine is a room temperature gas, and hydrogen...
1 Answers 1 viewsThe stoichiometrically balanced equation tells us unequivocally that $1$ $mol$ dihydrogen reacts with $0.50$ $mol$ dioxygen to give $1$ $mol$ water. $"Moles of dihydrogen"$ $=$ $(58.1*g)/(2.02*g*mol)$ $=$ $28.7*mol$ $H_2$ $"Moles...
1 Answers 1 viewsThis shouldn't feel too complicated... We know: what the vapor pressure of water vapor plus hydrogen gas is. what the vapor pressure of just water vapor is. Hence,...
