Definition
ROMAN NUMERAL
Term
Which family in the periodic table does not form binary compounds?
Definition

GROUP 8A

(the Nobel or Inert Gases)

Term

Term
An atom which forms a -3 ion would most likely be in which family?
Definition

group 5A

 (the Nitrogen family)

Term
When combined with the element sulfur, which one of the following elements would most likely come first in the formula? Br F Si O
Definition
Si (because it is further to the left in the periodic table - more metallic - and would tend to lose electrons to the sulfur to become the (+) cation.

Definition
dinitrogen tetraoxide = N2O4  (F.W. = 92)


64/92 X 100 = 69.6% oxygen
Term
Calculate the % of nitrogen in nitrogen triiodide.
Definition
nitrogen triiodide = NI3  (F.W. = 394.7)


14/394.7 X 100 = 3.5 % nitrogen
Term

A compound is found to contain 70.0 % Iron and 30.0 % oxygen.  Determine the empirical formula from the above information and name the compound.

Definition

Fe2O3

Iron III oxide

 

Step 1:  divide the percent by the element F.W. from the periodic table

Step 2:  divide the largest by the smallest numbers from the above step to get the empirical formula.

Term
How many grams are in 2.75 moles of Molybdinum sulfide?
Definition
One mole of MoS2 is equal to the formula weight of 160.2 grams.

2.75 mole x 160.2 grams  =  441 grams
                     1 mole
Term
