What is the mass of 7 moles of MgBr2?
Using a copy of the Periodic Table, showing the Atomic Masses. MgBr2 1 x Mg = 1 x 24 = 24 2 x Br = 2 x 80 = 160 24 + 160 = 184 the Mr ( Relative Molecular Mass) of tne molecule of MgBr2 Using the equation. moles = mass(g) / Mr Then mass(g = moles X Mt So for '7' moles mass(g) = 7 x 184 = 1288 g = 1.288 kg ( kilograms).

Formula for magnesium bromide?
The chemical formula of magnesium dibromide is MgBr2.
How many anions are there in MgBr2?
Two(2). They are ' Br^(2) ' . The terminal '2' indicates that there are two anions. NB Collectively they are IONS . Positively charged ions are ' CATIONS'. M^(n+) Negatively charged ions are ' ANIONS'. X^(n-) MgBr2 = Mg^(2+) ' positively charged cation 2Br^(-) ' negatively charged anions. For an ionic compound to be neutral , the charged MUST balance and be opposite. (+/-) Hence MgBr2 = 2+ for magnesium and "2 x -1 = -2 ' for the two bromines. Hence + 2 - 2 = 0
What does the two mean out of magnesium bromine 2?
The chemical formula of magnesium bromide is MgBr2; 2 is the number of bromine atoms in the molecule.
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.
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 is the oxidation state of Br in MgBr2?
The oxidation state of Br in MgBr2 is -1. Magnesium (Mg) typically has an oxidation state of +2, which means that the two bromine atoms in MgBr2 must have an oxidation state of -1 to balance the charge.
What does the 2 indicate in the formula mgbr2?
The "2" in MgBr2 indicates that magnesium (Mg) forms an ionic compound with two bromide ions (Br-). This means that magnesium will have a 2+ charge to balance the 2- charge of the two bromide ions.
What is the correct name for MgBr2?
Magnesium bromide
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 balanced equation for magnesium bromide and chlorine?
Bromine is diatomic, so 2 atoms make up Bromine as a reactant. Mg + Br2 ----> MgBr2
