A 0.5 mole sample of He(g) and a 0.5 mole sample of Ne(g) are placed separately in two 10.0 L rigid containers at 25 ℃. Each container has a pinhole opening. Which of the gases, He(g) or Ne(g), will escape faster through the pinhole and why? - ANSWER He(g) will escape faster because the He(g) atoms are moving at a higher average speed than the Ne(g) atoms. The lattice energy of a salt is related to the energy required to separate the ions. For which of the following pairs of ions is the ene...

A sample of 9.00 grams of aluminum metal is added to an excess of hydrochloric acid. The volume of hydrogen gas produced at standard temperature and pressure is (A) 22.4 liters (C) 7.46 liters (B) 11.2 liters (D) 5.60 liters - ANSWER (B) 11.2 liters What is the net ionic equation for the reaction that occurs when aqueous copper(II) sulfate is added to excess 6- molar ammonia? (A) Cu2+ + SO42- + 2 NH4+ + 2 OH- -> (NH4)2SO4 + Cu(OH)2 (B) Cu2+ + 4 NH3 + 4 H2O -> Cu(OH)4²- + 4 NH4+ ...

Which of the following has the largest bond dissociation energy? Li2 Which of the following diatomic species has a bond order of 2? Li2 B2 N2 O2 F2 - ANSWER O2 (O2 has a double bond) B2 N2 O2 F2 - ANSWER N2 (because N2 has a triple bond, making it have the largest bond dissociation energy) The geometry of the SO3 molecule is best described as - ANSWER trigonal planar In which of the following process are covalent bonds broken? I2(s) → I2(g) CO2(s) → CO2(g) NaCl(s) → ...
