To determine the empirical formula of the compound given, we need to determine the ratio of each element in the compound. To do that we assume to have 100 grams sample of the compound with the given composition. Then, we calculate for the number of moles of each element. We do as follows:<span>
         mass        moles
C       56.79        4.73
H       6.56          6.50
O       28.37        1.77
N      8.28           0.59

Dividing the number of moles of each element with the smallest value, we will have the empirical formula:

</span>         moles                 ratio
C       4.73     / 0.59       8
H       6.50     / 0.59      11
O       1.77     / 0.59       3
N        0.59    / 0.59       1<span>
</span><span>
The empirical formula would be C8H11O3N.</span>

A chemical reaction resulting in the transfer of electrons or hydrogen atoms from one molecule to another is called a(n) _______
anzhelika [568]

The kind of reaction involving the transfer of electrons or hydrogen away from a molecule is called oxidation.

In the same vein, the molecule that receives the electron or the hydrogen atom is said to be reduced. This means that oxidation cannot exist in isolation without reduction.

In other words, oxidation is defined as:

  • Loss of electrons
  • Loss of hydrogen atoms
  • Gain of oxygen atoms
  • Gain in oxidation number

While reduction is defined as:

  • Gain of electrons
  • Gain of hydrogen atom
  • Loss of oxygen atom
  • Reduction in oxidation number
