What is the chemical formula for magnesium- bromide?
The chemical formula for magnesium bromide is MgBr2. This compound is composed of one magnesium ion (Mg2+) and two bromide ions (Br-).
What is oxidation number of BrO3?
The oxidation number of Br in BrO3- is +5. This is because oxygen typically has an oxidation number of -2, and since there are three oxygen atoms in the BrO3- ion, the total negative charge is -6. Since the overall charge of the ion is -1, the oxidation number of Br must be +5 to balance the charges.
What is the oxidation of Br2-?
Each Br atom has an oxidation number of zero.
Is MgBr2 a compound?
Yes, MgBr2 is a compound. It is formed from magnesium (Mg) and bromine (Br) ions with a 1:2 ratio, resulting in the compound magnesium bromide.
What is the chemical formula for bromine mononitride?
The chemical formula for bromine mononitride is BrN.
What is the oxidation of each ion in the compound MgBr2?
In the compound MgBr2, magnesium (Mg) has an oxidation state of +2 and bromine (Br) has an oxidation state of -1. This is because the overall charge of the compound is neutral, so the sum of the oxidation states of each element must equal zero.
What is the oxidation number of each ion in the compound MgBr2?
In MgBr2, the magnesium ion (Mg) has an oxidation number of +2, while the bromide ion (Br) has an oxidation number of -1.
Is MgBr2 a metal?
Yes, MgBr2 is a chemical compound composed of magnesium (Mg) and bromine (Br), where magnesium is a metal. MgBr2 is an ionic compound where magnesium has a +2 oxidation state, making it a metal in this compound.
What does the 2 mean out of MgBr2?
If you meant MgBr2 - it means there are two atoms of Br to one of Mg
What is the mass of 7 moles of MgBr2?
The molar mass of MgCl2 = 95.211 g/mol
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 Br-?
The oxidation number of Br- is -1. Bromine typically has an oxidation state of -1 when it forms an ion by gaining one electron.
How many anions are there in MgBr2?
In MgBr2, there are two bromide anions (Br-) for each magnesium cation (Mg2+), so the total number of anions in MgBr2 is 2.
What is the oxidation number of each ion in MgBr2?
In MgBr2, magnesium (Mg) has an oxidation number of +2 as it typically loses two electrons to achieve a stable octet. Bromine (Br) has an oxidation number of -1 since it typically gains one electron to complete its valence shell.
How many anions are there in 2.50 g of MgBr2?
There are a total of 2 moles of anions in 2.50 g of MgBr2. Each formula unit of MgBr2 contains 2 moles of anions (Br-). The molar mass of MgBr2 is 184.113 g/mol, so 2.50 g is equivalent to 0.0136 moles, and therefore 0.0136 moles * 2 moles = 0.0272 moles of anions.
What is an ionic formula for Mg and Br?
The ionic formula for Mg and Br is MgBr2, with magnesium having a 2+ charge and bromine having a 1- charge. MgBr2 indicates that two bromide ions combine with one magnesium ion in the compound.
What is the oxidation state of each element in FeBr3?
In FeBr3, iron (Fe) has an oxidation state of +3 and bromine (Br) has an oxidation state of -1. Each bromine atom contributes -1 oxidation state, and since there are three bromine atoms, the total is -3, balancing the +3 oxidation state of iron for the compound to be neutral.
