Question 1

Nitric oxide, NO, is made from the oxidation of NH3, and the reaction is represented by the equation:

4NH3 + 5O2→ 4NO + 6H2O

A 9.3-g sample of NH3 gives 12.0 g of NO. The percent yield of NO is _____.


◦ 78%
◦ 59%
◦ 46%
◦ 73%
◦ 18%

Question 2

On another planet, boron has two isotopes as follows:

       Isotope                         Mass (amu)                            Natural Abundance (%)

       Boron-10                     10.0129                                   80.00

       Boron-11                     11.0093                                   20.00

Estimatethe average atomic mass of boron on this planet.


◦ 10.0 amu
◦ 11.0 amu
◦ 10.5 amu
◦ 10.8 amu
◦ 10.2 amu
