One mole of dichlorine heptoxide contains how many molecules?
One mole contains anumber of Molecules called Avogadro's number N=6.022*10^23 as its formula contains 7 atoms oxygen by molecule than 7*6.022*10^23=4.215*10^24 molecules
Why is oxygen required for fire? Are there any other elements that can be used instead of oxygen to fuel fire or create something like fire?
A fuel is oxidized by oxygen to yield oxides and heat. For a reaction to take place, there must be something to react with, and in our atmosphere, oxygen is the only reactant.There are several other elements, like fluorine and chlorine, that can oxidize a fuel. Many materials will burn in chlorine just like oxygen, but fluorine is even more reactive and will make water burn! There are several other compounds that can act like oxygen like dichlorine heptoxide-Cl2O7 or dichlorine hexoxide. There are several compounds of oxygen and fluorine and fluorine and chlorine that are also powerful oxidizers.The fluorine and chlorine oxidizers create something like a fire, but the products of the reaction are usually highly toxic and corrosive.
Why does an oxidizing agent accept electrons?
Some might contain elements in very high, unstable oxidation states, and will oxidize things to reduce it to a more stable oxidation state, such as manganese heptoxide (Mn2O7) with manganese in the +7 oxidation state. Some will oxidize to fill their electron shells.
What is the correct name for the following elements?
1. P4O5 A. potassium (IV) pentoxide C. diphosphorus tetroxide B. tetraphosphorus heptoxide D. phosphorus pentoxide E.None of the above 2. Al2O3 A. aluminide oxide B. aluminum oxide C. aluminum trioxide D. aluminum (III) oxide E.None of the above. 3. CaBr2 A. calcium bromide B. calcium (I) bromide C. calcium bromine D. calciumic bromide E.none of the above. 4. Nb2O5 A. niobium (II) oxide B. niobium oxide C. niobium (V) oxide D. diniobium pentoxide E.None of the above.
What is the oxidation number of O in Cl2O7?
We know Cl show diffrent oxidation state as -1 to +7 due to vacant d orbital. Here first we have to know which atom is more electronegative between Cl and O. Oxygen size is small hence it's more electronegative and show -2 oxidation state.Here Cl2O7 then equation is: 2x+ 7×(-2) = 0x= +7 hence oxidation state of Cl is +7. I think you get your answer how to find oxidation state.
Which is the strongest acidic oxide?
Among simple acids, perchloric acid (HClO4) is usually considered the strongest. It is an oxoacid of chlorine in which the halogen is in its maximum oxidation state of +7.The anhydride of perchloric acid is chlorine heptoxide, Cl2O7. Chlorine heptoxide dissolves in water to give perchloric acid. It should be the most acidic among all known oxides.
What is the chemical name of water?
Well the naming of covalent compounds rules applies. Water is made from hydrogen and oxygen, two nonmetals.The first element listed gets a prefix di- since there are two hydrogens in H2O. So the first part of the name is dihydrogenThe second (and last element) listed will end in the ending -ide. So since there are no more than one oxygen you will just go with oxide.So it’s dihydrogen oxide.NOW… the other way is to have the oxide take the prefix mono- cause there is only one oxygen. So the name becomes dihydrogen monoxide.
What compounds can oxygen and chlorine form?
Cl2O : Dichloromonoxide : a brown gas, red-brown liquid. mp minus 11.6 degrees C. bp 2 degrees C. Decomposes at 100 degrees C. Explodes on heating or shock.Cl202 : Chlorine I peroxide : orange yellow gas. Red liquid. Orange-red crystals. mp minus 59 degrees C. bp 11 degrees C. Unstable at room temperature. Explodes on slight disturbance.Cl2O6 : Dichlorine hexoxide : red liquid. Orange solid at minus 78 degrees C. mp 3.5 degrees C. Decomposes at melting point. Not highly explosive except when in contact with organic compounds. Cl2O6 is in fact only the correct formula in the gaseous state. In the liquid and solid state it exists as ClO3 or [ClO2]+ [ClO4 ]-Cl2O7 : Dichlorine heptoxide : oily colourless liquid. Colourless solid. mp minus 91.5 degrees C. bp 83 degrees C. Fairly stable nut liable to explode on shock or distillation.Cl2O3 : Dichlorinetrioxide. Discovered in 1967. It is a dark brown solid, explosive even below zero degrees CCl2O4 : Chlorine perchlorate. It is a pale green liquid that decomposes at room temperature.ClO• : Chlorine monoxide is a chemical radical. It plays an important role in ozone depletion.ClOO : Chloroperoxyl( OClO3 )2 : Chlorine VII oxide peroxideIons of Chlorine & Oxygen :ClO2+ ChlorylClO3+ PerchlorylClO- HypochloriteClO2- ChloriteClO3- ChlorateClO4- Perchlorate
