The correct equation is #"4NH"_2"CH"_2"COOH(s)" + "9O"_2("g")"##rarr##"8CO"_2("g") + 10"H"_2"O"("l")" + 2N"_2"# .

Explanation:

It is not properly balanced. A balanced equation should have only whole number coefficients.

#"NH"_2"CH"_2"COOH(s)" + "9/4O"_2("g")"##rarr##"2CO"_2("g") + "5/2H"_2"O"("l") + "1/2N"_2("g")"#

The common denominator of the fraction coefficients is 4. Multiply all coefficients times 4.

#"4NH"_2"CH"_2"COOH(s)" + "9O"_2("g")"##rarr##"8CO"_2("g") + (5*4)/2"H"_2"O"("l")" + (1*4)/2N_2#

Simplify the fractions on the right side of the equation.

#"4NH"_2"CH"_2"COOH(s)" + "9O"_2("g")"##rarr##"8CO"_2("g") + 20/2"H"_2"O"("l")" + 4/2N_2#

Reduce the fractions on the right side.

#"4NH"_2"CH"_2"COOH(s)" + "9O"_2("g")"##rarr##"8CO"_2("g") + 10"H"_2"O"("l")" + 2N"_2"#
