Question

The chemical eqaution H squared + Cl squared > 2 HCl represents which type of reaction?

Thanks, if you can get it):

Answer 1

Many words would fit, such as

binary
gaseous
exothermic
explosive
balanced

When an element has a subscript "2", you don't call it "squared". Just say "H two" or "C L two" in this case.

You seem to be confusing your chemistry with math.
