2

• A reaction occurs between sodium carbonate and hydrochloric acid producing sodium chloride, carbon dioxide, and water. The correct set of coefficients, respectively, for the balanced reaction is ___.

3

• Which type of substance is often easily separated into its components by simple techniques such as filtering or decanting?

4

• Copper has a density of 8.960 g/cm3. A block of copper that measures 1.01 cm x 4.01 cm x 1.50 cm, what is the mass of the copper?

5

•What are the four quantum numbers for the outermost electrons in a phosphorus atom?

6

Consider three 1-L flasks at STP. Flask A contains NH3 gas, flask B contains NO2 gas, and flask C contains N2 gas.• Which contains the largest number

of molecules?• In which flask would the molecules

have the greatest kinetic energy?

7

Consider the balanced equation: 2H2 + O2 2H2O

• What volume of oxygen in liters must be available at STP to allow 6.00 g of hydrogen to react and form water?

8

• The oxidation number of the chromium atom in the dichromate ion (Cr2O7

2-) is___.

9

•What conditions with temperature and pressure will cause an ideal gas to act like a real gas?

10

•Which quantum number describes the shape of an orbital?

11

•What is the relationship between bond order and bond length?

12

•Which elements have an electronegativity 3 or above?

13

•Resonance structures differ by __.

The Answers

1

• Protons = 26, neutrons = 30, and electrons = 26

2

Na2CO3 + 2HCl 2NaCl + CO2 + H2O

•1, 2, 2, 1, 1

3

•Heterogeneous mixture

4

•54.4 g

5

•(3, 1, -1, ½)

6

Consider three 1-L flasks at STP. Flask A contains NH3 gas, flask B contains NO2 gas, and flask C contains N2 gas.• All contain the same number of

molecules• All have the same kinetic energy

because they are at the same temp

7

Consider the balanced equation: 2H2 + O2 2H2O

•33.3 L

8

• The oxidation number of the chromium atom in the

dichromate ion (Cr2O72-) is +6.

9

•High pressure or low temperature. • Both will cause the volume to be

low which in turn will cause the particles to be very close together.

10

•Azimuthal (l)

11

•As bond order increases, bond length decreases

12

•N, O, F, Cl

13

•Resonance structures differ by the arrangement of the electrons.
