Question

balancing chemical equations
c₃h₈ + o₂ → co₂ + h₂o
multiple - choice question
which element(s) should we start balancing first?
o
h
c

Explanation:

When balancing chemical equations, it is a common practice to start with elements other than hydrogen and oxygen. In this equation, carbon (C) is such an element. Hydrogen (H) and oxygen (O) are often balanced later as they are more flexible in the balancing process.

Answer:

C. C (Carbon)
