Match the term to the correct definition or example.

the amount of energy required to remove an electron from an atom.

a bond where electrons are shared unequally, resulting in a positively charged end and a negatively charged end of the molecule,

the tendency of an atom to attract a pair of electrons and bond with another atom; increases from bottom-left toward top-right of the periodic table.

a bond where electrons are shared equally, or polar bonds in the molecule cancel each other out.

shell or energy level where electrons are found.

1.
orbital

2.
ionization energy

3.
electronegativity

4.
polar covalent bond

5.
nonpolar covalent bond

The amount of energy required to remove an electron from an atom. 2 ionization energy

A bond where electrons are shared unequally, resulting in a positively charged end and a negatively charged end of the molecule, 4 polar covalent bond

The tendency of an atom to attract a pair of electrons and bond with another atom; increases from bottom-left toward top-right of the periodic table. 3. Electronegativity

A bond where electrons are shared equally, or polar bonds in the molecule cancel each other out. 5. Non polar covalent bond

Shell or energy level where electrons are found. 1. Orbital

n2(g) + 3h2-> 2nh3(g)   this is the balanced equation

note the mole ratio between n2, h2 and nh3.   it is 1 : 3 : 2   this will be important.

moles n2 present = 28.0 g n2 x 1 mole n2/28 g = 1 mole n2 present

moles h2 present = 25.0 g h2 x 1 mole h2/2 g = 12.5 moles h2 present

based on mole ratio, n2 is limiting in this situation because there is more than enough h2 but not enough n2.

moles nh3 that can be produced = 1 mole n2 x 2 moles nh3/mole n2 = 2 moles nh3 can be produced

grams of nh3 that can be produced = 2 moles nh3 x 17 g/mole = 34 grams of nh3 can be produced

note:   the key to this problem is recognizing that n2 is limiting, and therefore limits how much nh3 can be produced.

the answer is   c.) 1575 j.
