Question

what are the correct coefficients to balance the above chemical equation? 2,3,2,8 it is already balanced 1,5,3,4 1,5,3,4

Explanation:

Step1: Balance carbon atoms

Let the coefficient of \(C_3H_8\) be \(a\), \(O_2\) be \(b\), \(CO_2\) be \(c\), and \(H_2O\) be \(d\). For carbon: \(3a = c\).

Step2: Balance hydrogen atoms

For hydrogen: \(8a=2d\), so \(d = 4a\).

Step3: Balance oxygen atoms

For oxygen: \(2b=2c + d\). Substitute \(c = 3a\) and \(d = 4a\) into \(2b=2c + d\), we get \(2b=2\times3a+4a=10a\), so \(b = 5a\).
If \(a = 1\), then \(b = 5\), \(c = 3\), \(d = 4\).

Answer:

\(1,5,3,4\)
