Question
Chapter 3, Problem 3.64QP
Interpretation Introduction
Interpretation: Among the following equations, the equation best representing the given diagram in the problem statement has to be identified.
Concept Introduction:
- Chemical equation is the symbolic representation of a
chemical reaction using thesymbols of elements. Chemical equation must be balanced on both sides (reactant side and product side) of the reaction. A balanced equation alone obeys the "Law of conservation of mass" - Balancing a chemical equation is based on "trial-and-error" method.
- For each step during balancing of chemical equation, the atoms involved in reaction are listed out. Then the number of atoms on both sides of the reaction (reactant side and product side) is checked for tally.
- Suitable numerals are placed as coefficients before the element or compound on either side of reaction wherever necessary.
- Placing of coefficients are allowed for balancing equation, whereas changing the subscripts of elements or compounds are not allowed.
- Always place coefficients for compounds first rather than placing it for elements.
- Polyatomic ions can be treated as single unit on both sides rather than considering their constituents individually.
- While balancing the equation, the numerals used must be simple whole number.
To Identify: The best equation representing the given diagram

The complete combustion of gasoline (C8H18) is best represented by which of the following equations
Options:
2 C8H18 (l) + 25 O2 (g) → 16 CO2 (g) + 18 H2O(l)
2 C8H18 (l) + 17 O2 (g) → 16 CO (g) + 9 H2O (l)
C8H18 (l) + O(g) → 8 CO2 (g) + 9 H2O (l)
