Can someone plz help me im running out of time Balance the chemical equation below using the smallest possible whole number
stoichiometric coefficients.

Q1= C(s)+H2(g) -> C2H6(g)
Q2= NH3(g)+O2(g)-> HCN(aq)+H2O(l)

1. C(2)+H2(1) -> C2H6(1)

2. NH3(2)+O2(3)-> HCN(2)+H2O(3)

I am not sure about the second one.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
