When I put a burning splint into the test tube it made a popping noise. What gas was produced?
-
It would have to be H2 gas.
Zn + H2SO4 -> ZnSO4 + H2
when you put a burning splint in the H2 combines with O2 in the air to produce water
2H2 + O2 -> 2H2O
Zn + H2SO4 -> ZnSO4 + H2
when you put a burning splint in the H2 combines with O2 in the air to produce water
2H2 + O2 -> 2H2O
