Balancing equation?
a.2 C6H6(λ) + 15 O2(g) → 12 CO2(g) + 6 H2O(g)
b.C6H6(λ) + 12 H2O(λ) → 6 CO2(g) + 15 H2(g)
c.2 C6H6(λ) + 9 O2(g) → 12 CO (g) + 6 H2O(g)
d.C6H6(λ) + O2(g) → CO2(g) + H2O(g)
e.C6H6(λ) → 6 C(s) + 3 H2(g)
Answer:
The answer is a. You can easily remove answers b and e, for combustion requires oxygen. Furthermore answer c can be removed for it contains the incorrect molecule 'co' and answer d is unbalanced with three oxygen on the products side and only two on the reactants side. If you check all the quantities of atoms, a is the only choice that makes sense and is balanced.
