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).

The reaction between hydrogen and fluorine.

Explanation:

The balanced chemical equation of the reaction is:

From the balanced chemical equation, it is clear that:

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

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
