  2C₇ H₆O₂   +  15O₂   →    14CO₂     +     6H₂O

Explanation:

Balancing the chemical equation ensures that reactions are based on the law of conservation of mass.

According to the law, we must ensure that the amount of species on both sides of the equation must be the same.

  The reaction given is a combustion reaction:

        C₇ H₆O₂   +  O₂   →    CO₂     +     H₂O

let us balance this equation using mathematical approach.

          aC₇ H₆O₂   +  bO₂   →    dCO₂     +     eH₂O

a,b,d and e are the coefficients that will balance the equation.

 Conserving C: 7a = d

                     H:  6a = 2e

                     O: 2a + 2b = 2d + e

let a = 1

      d = 7

       e = 3

       b = \frac{15}{2}

multiply through by 2;

  a = 2, b = 15, d = 14, e = 6

        2C₇ H₆O₂   +  15O₂   →    14CO₂     +     6H₂O

Select the correct answer.
Nuetrik [128]

Answer:

A binary covalent compound is composed of two different elements (usually nonmetals). For example, a molecule of chlorine trifluoride, ClF3 contains 1 atom of chlorine and 3 atoms of fluorine.

Rule 1. The element with the lower group number is written first in the name; the element with the higher group number is written second in the name. Exception: when the compound contains oxygen and a halogen, the name of the halogen is the first word in the name.

Rule 2. If both elements are in the same group, the element with the higher period number is written first in the name.

Rule 3. The second element in the name is named as if it were an anion, i.e., by adding the suffix -ide to the root of the element name (e.g., fluorine = F, "fluoride" = F-; sulfur = S, "sulfide" = S2-).

Rule 4. Greek prefixes are used to indicate the number of atoms of each element in the chemical formula for the compound. Exception: if the compound contains one atom of the element that is written first in the name, the prefix "mono-" is not used.
