h2 -16h+15 = (h -1)(h -15) when factored
H2 - hydrogen.
Yep
It is not balanced. There should be a 2 in front of H2 and H2O
C2h2+ 2h2 = c2h6
It's a chemical reaction.
single replacement
Yes, it is correct.
Yes it is.
No. Zn + 2HCl = ZnCl2 + H2
It is an eothermic type of reaction.
2SO2 + O2 + 2H2O -------> 2H2SO4
It is an expression and a term that are of equal value
