Question

Write a balanced chemical equation for the standard formation reaction of gaseous hydrogen fluoride hf

Answer 1

the standard state formation reaction is a chemical reaction in which one moles of substance in its standard state is formed from its constituent element in their standard state.All the substance must be in their most stable state at 100kpa and 25 degrees celsius.
therefore for HF is
1/2H2 +1/2F2 =HF

Answer 2

Answer: A balanced chemical equation for the standard formation reaction is
`(1)/(2)H_(2)(g)+(1)/(2)F_(2)(g)\rightarrow HF(g)`

Step-by-step explanation:

A balanced chemical equation is the equation in which number of reactants equals the number number of products.

The balanced chemical equation for the formation of gaseous hydrogen fluoride is as follows.

`(1)/(2)H_(2)(g)+(1)/(2)F_(2)(g)\rightarrow HF(g)`

Here, in this equation half molecule of
`H_(2)` reacts with half molecule of
`F_(2)` to give 1 molecule of HF.

Thus, the sum of number of reactant molecules equals the number of product molecules. Therefore, it is a balanced equation.

Therefore, the equation is
`(1)/(2)H_(2)(g)+(1)/(2)F_(2)(g)\rightarrow HF(g)`
