Question

In the following equation, which product is a diatomic molecule?

2 Na + 2 HCl → 2 NaCl + H

2Na

H

2HCl

all the above

Answer 1

There should actually be a subscript of 2 on the H. Hydrogen is one of the diatomic molecules, meaning that it is only found in nature in pairs of 2. The second answer is correct.
