What are the elements that make up HF?
Hydrogen and fluorine are the two elements that make up hydrogen fluoride (HF).
What elements are found in hf?
H- Hydrogen F- Fluoride
Write an equation for the formation of HF gas from its elements in its standard states?
The equation for the formation of HF gas from its elements in their standard states is: H2(g) + F2(g) → 2HF(g)
Equation for the heat of formation of carbon disulphide?
The heat of formation (∆Hf) of carbon disulfide (CS2) can be calculated using the standard enthalpies of formation of its constituent elements as follows: ∆Hf (CS2) = ∆Hf(C) + 2∆Hf(S) − ∆Hf(CS2). The standard enthalpies of formation for carbon (C) and sulfur (S) are known values and can be used in the calculation.
Can HF be decomposed by a chemical change?
No, hydrofluoric acid (HF) cannot be decomposed by a chemical change because it is a stable compound. Physical methods are typically used to separate HF into its constituent elements.
What does a negative Hf for molecule mean?
Energy was released when the molecule was formed from its elements
What is the molecular formula for hydrofluoric acid?
The acids formed by the halogen elements are ;- HF ; Hydrofluoric acid HCl ; Hydrochloric acid HBr ; Hydrobromic acid HI ; Hydroiodic acid.
What is the polar molecule.?
if i believe it is HF but just subtract the electronegativies of the two elements in a multiple choice question
What elements have hen as a part of its name?
rhenium, ruthenium
What does positive Hf for a molecule mean?
A positive enthalpy of formation (Hf) for a molecule indicates that the formation of that molecule from its constituent elements is an endothermic process, meaning it absorbs heat. This typically suggests that the molecule is less stable compared to its elements and requires energy input to form. In practical terms, a positive Hf value often signifies that the molecule is not favored to form under standard conditions.
How is Hf related to the H of a reaction?
The Hreaction is the difference between Hf, products and Hf, reactants
What elements are hydrogen fluride made up of?
Hydrogen fluoride: HF. hydrogen and fluorine. Please see the link.
