10. Which of the following chemical equations is an acid-base reaction? a. 2 HCl(aq) + Zn(s) → H2(g) + ZnCl2(aq) b. HCl(aq) + NH3(aq) → NH¼C((aq) c. HCl(aq) + A£NO:(aq) → AgCl(s) + HNO:(aq) d. Ba(OH)2(aq) + NażSO4(aq) → BaSO4(s) + 2 NaOH(aq) e. 2 NaOH(aq) + CuCl2(aq) → Cu(OH):(s) + 2 NaCI(aq) 11. The number of electrons in the highest energy level of 20Ca is a. 2 b. 4 c. 5 d. 6 e. 8 12. The word Aufbau means building up in German. The Aufbau Principle describes that a. electrons with the same spin cannot occupy the same orbital. b. Since electrons repel each other, electrons will occupy single orbitals within and energy level before doubling up. c. electrons fill lower energy levels first before occupying higher energy levels. d. All of the above. e. None of the above.
