Question

_________one moleculetwo moleculesone moletwo moles of H2(g) reacts with _________one moleculetwo moleculesone moletwo moles of F2(g) to form _________one moleculetwo moleculesone moletwo moles of HF(g).

Answer 1

The reaction between hydrogen and fluorine.

Step-by-step explanation:

The balanced chemical equation of the reaction is:

`H_2(g)+F_2(g)->2HF(g)`

From the balanced chemical equation, it is clear that:

1 mole of
`H_2` gas reacts with one mole of
`F_2(g)` and forms 2 moles of HF(g).
