The principal reason is the hydrogen bonding between HF molecules. The second reason is that London dispersion forces will be higher in HF because it has more electrons than H2
intermolecular forces. In the case of HF, hydrogen bonding exists between HF molecules, which results in stronger intermolecular attractions compared to the London dispersion forces present in H2 and F2. These stronger intermolecular forces in HF allow it to exist as a liquid at room temperature.
H2 is the molecular formula for hydrogen gas; H is the chemical formula for one atom of hydrogen, whether it be gas, liquid, or solid.
3 H2 + N2 = NH3
Hf refers to the chemical element hafnium, a transition metal with atomic number 72. HF refers to hydrofluoric acid, a colorless and highly corrosive acid. Hafnium is a solid metal used in nuclear reactors and electronics, while HF is a liquid acid used in various industrial processes.
The two colorless gases that combine to form a colorless liquid are hydrogen gas (H2) and oxygen gas (O2), which react to form liquid water (H2O) through a chemical reaction.
intermolecular forces. In the case of HF, hydrogen bonding exists between HF molecules, which results in stronger intermolecular attractions compared to the London dispersion forces present in H2 and F2. These stronger intermolecular forces in HF allow it to exist as a liquid at room temperature.
The equation for the formation of HF gas from its elements in their standard states is: H2(g) + F2(g) → 2HF(g)
HF [note correct capitalization] is not an element but a compound, since it contains two kinds of atoms. It is a gas at standard temperature and pressure.
When hydrogen gas reacts with fluorine gas, the product formed is hydrogen fluoride (HF) gas.
HF is a very corrosive gas at room temperature. It can even etch glass!
where liquid Hf is used
Hydrogen is not a liquid at room temperature. H2 changes from gas to liquid state at about -253oC .
H2 is the molecular formula for hydrogen gas; H is the chemical formula for one atom of hydrogen, whether it be gas, liquid, or solid.
The balanced reaction for the reaction of uranium fluoride, water and hydrogen gas is UF6 + 2 H2O + H2 = UO2 + 6 HF. The final products are uranium oxide and fluoric acid.
2Si +2HF-2siF + 2H
Does this mean: How does potassium (capital K, solid reactive metal) react with hydrogen fluoride (capitals HF, weak but reactive acid when in water solution)) then the answer is in the next reaction equation: 2K + 2HF --> 2KF + H2 Products are: KF potassium fluoride, H2 gas, very explosive with air.
