The forces that account for HF being a liquid while H2 and F2 are gases are known as?
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.
Is h2 a atom or molecular?
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.
What is the chemical equation liquid nitrogen reacts with an excess of hydrogen gas?
3 H2 + N2 = NH3
Explain the different between Hf and HF?
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.
Which are the 2 colorless gases that combine to form a colourless liquid?
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.
The forces that account for HF being a liquid while H2 and F2 are gases are known as?
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.
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)
Is the hf element a solid liquid or a gas?
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.
What is the product when hydrogen gas reacts with fluorine gas?
When hydrogen gas reacts with fluorine gas, the product formed is hydrogen fluoride (HF) gas.
What physical state is HF at room temp?
HF is a very corrosive gas at room temperature. It can even etch glass!
Where liquid Hf used?
where liquid Hf is used
Is hydrogen a liquid at room temprature?
Hydrogen is not a liquid at room temperature. H2 changes from gas to liquid state at about -253oC .
Is h2 a atom or molecular?
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.
Write a balanced equation for uf6 H2O h2 -------- uo2 hf?
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.
When Si plus HF equals SiF plus H2 is balanced what is the coefficient for HF?
2Si +2HF-2siF + 2H
What is an expression for k in hf in chemistry?
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.
What is the chemical equation liquid nitrogen reacts with an excess of hydrogen gas?
3 H2 + N2 = NH3
