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
What are the main gases released in a volcano?
H2o,co2,so2,h2,co,h2s,hcl,hf
Explain the different between Hf and HF?
Hf is the element hafnium. A dense gray metal. HF is the compound hydrogen fluoride, a toxic, acidic gas.
Formula for hydrogen?
Hydrogen gas is H2
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.
Where liquid Hf used?
where liquid Hf is used
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 formula equation hydrogen gas reacts with fluorine gas to produce hydrogen fluoride gas?
H2 + F2 -> 2HFhydrogen + fluorine -> hydrogen fluorideOne molecule of hydrogen reacts with one molecule of fluorine to produce two molecules of HF.
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.
What physical state is HF at room temp?
HF is a very corrosive gas at room temperature. It can even etch glass!
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
Formula hydrogen gas?
Its H2
What is the state of hydrogen at 20 degrees?
Hydrogen is a gas at 20 degrees, Fahrenheit and Celsius, but it you are talking Kelvin, then it is a liquid.
