Problem 61E
Further Applications of the Ideal-Gas Equation (Section)
Hydrogen gas is produced when zinc reacts with sulfuric acid:
Zn(s) + H2SO4(aq)→ZnSO4(aq) + H2(g)
If 159 mL of wet H2 is collected over water at 24 °C and a barometric pressure of 738 torr, how many grams of Zn have been consumed? (The vapor pressure of water is tabulated in Appendix B.)
Chapter 11: Liquids and Intermolecular Forces Wednesday, November 16, 2016 3:11 PM 4 Types of IntermolecularForces: • London Dispersion • Dipole-dipole • Hydrogen bonding • Ion-dipole Intermolecularforces are weaker than covalent/ionicbonds, but have profound effects on the properties of liquids and solids. London Dispersion forces: present in all molecules-temporary,partial charges give temporarypolarity • Only force in non-polar molecules and in unbonded atoms • London forces becomestronger, the larger the atom or molecule (larger electron clouds are easier to deform- polarizable) • Found in mixtures or pure substances The shape and size of the molecule affects the strength of dispersion forces: Long, skinny moleculestend to have stronger dispe
