Iron bromide is a chemical compound with chemical formula FeBr2. It is a anhydrous compound with yellow and brownish color paramagnetic solid. Iron is magnetic. So, any metal with iron will be attracted to a magnet. Some metals like copper, gold and aluminium are non-magnetic.
Not all iron is magnetic. Iron is a ferromagnetic which is attracted to the magnets like nickel and cobalt. It is non-magnetic because they have net dipole moment of zero and have partially field electron shell.
Iron bromide is magneticbecause it possses the strong magnetism at 4.2 degree kelvin.
In the diagram Carbon and each of the 4 Hydrogens are sharing electrons. They are also both non metals. Both of these are characteristics of Covalent Bonds.
Well as an spontaneous reaction will have a negative gibbs free energy (delta g) and a positive e cell and also the E cell is also measured in V, then your answer is the first one: ΔG = –295kJ, E°cell = +1.53 v. Hope this works
