Question

balance the following equation:
_c₃h₈+ _o₂→_co₂+ _h₂o
when the equation is properly balanced, the correct coefficients are, respectively

Explanation:

Step1: Balance carbon atoms

There are 3 carbon atoms in \(C_3H_8\). So, we put a coefficient of 3 in front of \(CO_2\).
\(C_3H_8+\ O_2
ightarrow3CO_2+\ H_2O\)

Step2: Balance hydrogen atoms

There are 8 hydrogen atoms in \(C_3H_8\). So, we put a coefficient of 4 in front of \(H_2O\).
\(C_3H_8+\ O_2
ightarrow3CO_2 + 4H_2O\)

Step3: Balance oxygen atoms

On the right - hand side, there are \(3\times2+4\times1=6 + 4=10\) oxygen atoms. So, we put a coefficient of 5 in front of \(O_2\).
\(C_3H_8+5O_2
ightarrow3CO_2+4H_2O\)

Answer:

1, 5, 3, 4
