Sectiоn 1: Fill in the blаnk (11 pts) Fill in the blаnk with the cоrrect аnswer. All shоrthand electron configurations begin with a [blank] in brackets. The energy of the reactants is higher than the energy of the products in an [blank] reaction. Oxygen typically forms [blank](#) bonds and has [blank](#) lone pairs. The maximum number of dots allowed around a symbol in a Lewis dot symbol is [blank]. In an [blank] electrons are signified with up and down arrows. The term used to describe the heat capacity of 1 gram of substance is [blank]. In a covalent bond, electrons are [blank]. Halogens have [blank] valence electrons. [blank] energy is the energy of movement while [blank] energy is stored energy. Section 2: True/False (4 pts) Answer true or false. If the answer is false, correct the statement. Lewis structures can have double, triple, and quadruple bonds. Heat always flows from system to surroundings. The s sublevel is higher in energy than the d sublevel. An exothermic reaction has a negative DH. Section 3: Multiple Choice (6 pts) Indicate the letter of the correct answer on your paper. Which of the following has the correct order of orbitals? 1s 2s 2p 3d 1s 2s 2p 3s 1s 2s 2p 3p The valence electron configuration for alkaline earth metals is: ns1 ns2np6 ns2 Which of the following is an exothermic process? Melting ice. Water condensing on side of glass. Boiling water. Section 4: Short Answer (29 pts) Show all work. Be sure to clearly indicate your answer. Draw a Lewis dot symbol for chlorine and for chloride and explain the difference. (3 pts) Write out the full and shorthand electron configuration and draw an orbital diagram for element number 34. (8 pts) A student must use 225 mL of hot water in a lab procedure. Calculate the amount of heat required to raise the temperature of 225 mL of water from 20.0°C to 100.0°C. Show ALL work, don't forget units and SF. c of water = 4.184 J/g°C, density of water is 1.0 g/mL. (4 pts) Complete the following table. (8 pts) Molecule Lewis Structure CO2 NF3 H2S CH2O A 12g piece of aluminum (c= 0.215 cal/g°C) is at 70°C. It is placed in a beaker that contains 35g of 15°C water (c= 1 cal/g°C). At what temperature will they come to thermal equilibrium? Show ALL work, don't forget units and SF. (6 pts)
