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

Answer:

The reaction between hydrogen and fluorine.

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).
