Is HF a oxyacid?
HF is not an oxyacid; no oxygen in the molecule.
When 1 gram of liquid water at 0 degrees celsius freezes to form ice how many total joules of heat are lost by the water?
a change from liquid to solid or solid to liquid will require the use of the formula of Heat of Fusion , q=mHf where m is the mass and Hf = 334J/g, this is standard so you wont have to look for how it came about.In this case the m=5.00g so: q = m Hf q=(5.00g)(334 J/g) , you notice the grams will cancel out. q = 1670 J.
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.
What is the chemical Formula of hydroflouric acid?
The chemical formula for Hydroflouric acid is HF It is not a very reactive acid but Fluorine,which is in this acid is very reactive
Reaction between UF6 H2O?
When uranium hexafluoride (UF6) reacts with water (H2O), it undergoes a violent exothermic chemical reaction that produces hydrogen fluoride (HF) gas and uranyl fluoride (UO2F2) as products. This reaction can release toxic fumes and should be handled with extreme caution due to the potential hazards associated with both UF6 and HF.
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.
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
Why is HF a liquid when H2 is a gas?
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
What is the name of the element hf?
Hafnium
Is HF an element or a compound?
Capitalization matters in chemistry. Hf (uppercase H, lowercase f) is the element known as hafnium. HF (both letters uppercase) is the compound known as hydrogen fluoride.
What is the total number of joules released when 5.00 gram sample of water changes from liquid to solid at 0 Celsius?
a change from liquid to solid or solid to liquid will require the use of the formula of Heat of Fusion , q=mHf where m is the mass and Hf = 334J/g, this is standard so you wont have to look for how it came about.In this case the m=5.00g so: q = m Hf q=(5.00g)(334 J/g) , you notice the grams will cancel out. q = 1670 J.
Is hafnium and element or compound?
Hafnium (Hf) is a natural chemical element.
How is the H fusion used to calculate the energy released when a mass of liquid freezes?
The heat of fusion is the amount of energy needed to change a substance from a liquid to a solid. To calculate the energy released when a mass of liquid freezes, you would use the equation Q = m * Hf, where Q is the energy released, m is the mass of the substance, and Hf is the heat of fusion.
Is Hf a hydrofluoric acid?
No. Hf is hafnium. HF is hydrofluoric acid. Capitalization matters when writing chemical formulas.
What is most likely to be a solid at room temperature na2s hf nh3 n2 h2o?
NH3 (ammonia) is most likely to be a gas at room temperature, while N2 (nitrogen) and H2O (water) are most likely to be liquids. Na2S (sodium sulfide) and HF (hydrogen fluoride) are solid at room temperature.
What element is Xe5d2?
Well, this should be Xe6s24f145d2 which is element number 72 hafnium (Hf).
