molecular mass of CO2=12+2×16
=12+32
=44g
No.of moles=Mass given/molar mass
=220/44
=5 moles answer
since I volume of N2 reacts with 3 volume of H2
therefore, ratio =1:3
since 1 molecules of n2 reacts with 3molecules of h2
therefore
5 molecules of n2 reacts with 15 molecules of h2
10).first test tube.
this is because concentrated HCl is more powerful than dilute HCl
mark it brainliest
