What else can I help you with?
Is fluorine combustible?
Yes it is flammable!. Fluorine gas is the most reactive of all the elements and quickly attacks all metals - steel wool bursts into flames when exposed to it! there u go! im sure you wanted to know this so there you go kids or adults.
Is flourine a metal or nonmetal?
Like all of the halogens, Fluorine is very much a nonmetal.
Why are bromine and iodine much denser than fluorine and chlorine?
Bromine and iodine are much denser than fluorine and chlorine because their larger atomic sizes result in more electrons and higher atomic masses. This leads to stronger van der Waals forces between the atoms, causing the molecules to be closer together and thus more densely packed.
Why is fluorine most electronegative than oxygen?
Electronegativity is an atoms relative ability to remove an electron pair in the formation of a covalent bond. I.e. an atoms ability to steal a pair of electrons from the outer ring of another atom to make a covalent bond, (like a contract to share electons in order to fill there outer shells and become stable) Across the periodic table (left to right) this gets harder to do due to an increase in attraction forces between the nuclear charge and the outer electons. Therefore across the periodic table 'more' electronegativity energy is required to remove those electrons. Down the periodic table, from top to bottom attraction forces between the electrons in the outer shell and the central nuclear charge decreases (shielding effect of sub levels and increased atomic radius), this make it easier for the electrons to be stolen, so there is less electronegativity required. Fluorine is the highest and furthest to the right, making it the most electronegative. (Helium and Neon etc have full outer shells so arent involved in covalent bonds)
Why is a nitrate ion a stronger base than a sulfide ion?
This is not true. The sulfide ion is a stronger base than the nitrate ion. This is because nitrogen and oxygen are very electronegative, This creates a stable anion with very little affinity for hydrogen ions. Sulfur is much less electronegative and so the sulfide ion is less stable. So it has a much higher affinity of a hydrogen ion.
Fluorine is more electronegative than oxygen?
That is correct. Fluorine is the most electronegative element on the periodic table, meaning it has a strong ability to attract electrons in a chemical bond. Oxygen is also very electronegative but not as much as fluorine.
Does fluorine have weaker or stronger intermolecular forces than iodine?
It depends. If Fluorine is bonded to Hydrogen then it would be greater, having present Hydrogen Bonding-the strongest Intermolecular Force. Iodine,I2, has many more electrons than fluorine, F2,so London dispersion forces are much stronger explaining why fluorine is a gas and iodine is a solid under standard conditions.
What is the role of an oxidizer in a solid fuel system?
A solid rocket engine uses a fuel and an oxidizer. The oxidizer when burned delivers oxygen to the fuel so that it can burn. Most rockets use oxidizers because when the rocket burns it uses so much oxygen that they need a readily available supply.
Why is lead four iodide unknown?
Lead(IV) iodide, or PbI4 is unknown and not present, because Iodine is not that much strong oxidizer to oxidize Lead or Lead(II) ions to Lead(IV) ions. However, Oxygen and Fluorine have this oxidizing power, and thus forming compounds of Lead(IV).
With a oxidizer can methane gas be a space rocket propellant?
Absolutely. Various rocket fuels are rated in "Specific Impulse", which is how much kick you get for how much fuel mass (or weight). This strongly influences the choice of fuels. Hydrogen and Oxygen is VERY high. Methane and Oxygen....not so much.
Is fluorine combustible?
Yes it is flammable!. Fluorine gas is the most reactive of all the elements and quickly attacks all metals - steel wool bursts into flames when exposed to it! there u go! im sure you wanted to know this so there you go kids or adults.
How much oxygen is needed to sustain combustion?
Oxygen is required to sustain combustion as it is the oxidizer that allows for the chemical reaction with the fuel. The exact amount of oxygen needed depends on the type of fuel being burned, as different fuels have different oxygen requirements for combustion. In general, combustion requires a sufficient supply of oxygen to ensure complete oxidation of the fuel.
How much does a gallon of fluorine cost?
As of August 2014, the cost for a gallon of fluorine is $25,600. Fluorine is not generally available for purchase by the public.
Is flourine a metal or nonmetal?
Like all of the halogens, Fluorine is very much a nonmetal.
What is the strongest oxidizing agent?
Oxidation is the loss of electrons and an element responsible for this loss is an oxidizing agent, an element which has great affinity for electrons is strong oxidizing agent , Fluorine atom has highest electronegatvity so it is strongest oxidizing element. oxidizing agent oxidizes others and itself becomes reduced.
What is the structure of TfOH?
Triflic acid, or TfOH, has a molecular formula of CF3SO3H. It is a strong acid with a trifluoromethyl group bonded to a sulfonyl group. The structure consists of a central sulfur atom surrounded by three fluorine atoms and a hydroxyl group attached to the sulfur.
Which bond is strongest hydrogen bonding or polar bonding?
Peptide bond is a covalent bond. Covalent bonds are stronger than hydrogen bonds. Think of electrons as the glue of a molecule. A covalent bond has electron interaction uniformity(They're glue is pretty consistent between two atoms). Now hydrogen bonds don't have as much glue; think of it as a few smeared drops of glue. So why do they have not as much glue(a weaker interaction than peptide bonds)? That's because Hydrogen bonds have hydrogens bonded to an electronegative atom(that means they like electrons). An example of an electronegative atom would be oxygen. Oxygen(or any given electronegative atom) will briefly take hydrogen's only electron when they pair up. So hydrogen's electron spends more time around the oxygen because it takes longer to circle around oxygen due to it being bigger than hydrogen. We know electrons have negative charge, so what happens when hydrogen's electron is over near the oxygen? Hydrogen gets a partial positive charge, and oxygen gets a partial negative charge!
