How many moles of Al are needed to form 2.43 mol of Al2Br6?
(2.43 mol Al2Br6)*(2 mol Al/ 1 mol Al2Br6)= 4.86 mol Al
What is the oxidation number of Br in Al2Br6?
The oxidation number of Br in Al2Br6 is -1. This is because the overall charge of the compound must be zero, and since we have two Br atoms each at -1 oxidation state, it balances out with the +3 oxidation state of Al.
What is the oxidation number of Al in Al2Br6?
The oxidation number of Al in Al2Br6 is +3. Each bromine atom has an oxidation number of -1, and since the compound is neutral, the sum of the oxidation numbers must equal zero. Hence, each Al atom must have an oxidation number of +3 to balance the -6 from the bromine atoms.
Aluminum will react with bromine to form aluminum bromide Al2Br6 What mass of bromine g is needed to form 1.42 mol of Al2Br6?
The gram formula unit or molar mass for aluminum bromide is 533.38.* Therefore, 1.42 moles has a mass of 757.4 grams. The mass of 6 moles of bromine atoms is 479.42. Therefore, the mass fraction of bromine in aluminum bromide is 479.42/757.4 or 0.633, and the mass in grams of bromine required to form 1.42 moles of aluminum bromide is 0.633 X 757.4 or 479 grams, to the justified number of significant digits (limited by the precision given for the number of moles.) ___________________ *This is equal to the sum of (2 times the gram atomic mass of aluminum) and (6 times the gram atomic mass of bromine).
What is the empirical formula for Al2Br6?
it is dimeric form of Aluminium bromide AlBr3
What is the molecular name for AL2Br6?
The molecular name for AL2Br6 is aluminum tribromide.

What is the name for the ionic compound for Li Br?
Lithium bromide, LiBr, is prepared by the treatment of lithium carbonate with hydrobromic acid
Why AlBr3 is ionic compound?
AlBr3 is not an ionic compound. The electronegativity difference between Al and Br is only 1.35 too low for an ionic compound to be formed.There are molecules of Al2Br6 present in the crystal lattice. These dimers are also present in molten AlBr3 and in the gaseous where it dissociates at high temperatures into molecular AlBr3. In the crystal the aluminium atoms are 4 coordinate with four bromine atoms tetrahedrally placed around each aluminium atom. This allows Al to achieve the octet. The bonding is polar covalent.
What type of bond is Aluminum Bromide?
Aluminum bromide is an ionic bond, formed by the transfer of electrons from aluminum to bromine to create positively charged ions (Al3+) and negatively charged ions (Br-).
Is table a salt a mixture or a compound?
It is a compound.
