Bromine (Br2) is a liquid at room temperature and pressure. It can be converted to a gas by heating it above its boiling point of 58.8°C.
The correct chemical equation for the reaction is: Cl2 + 2KBr → 2KCl + Br2. The reaction involves chlorine gas (Cl2) reacting with potassium bromide (KBr) to form potassium chloride (KCl) and bromine gas (Br2).
Br2 + 3NaHSO3 = 2NaBr + NaHSO4 + H2O + 2SO2
The chemical equation is:2 AlBr3 + 3 Cl2 = 2 AlCl3 + 3 Br2
44.0 grams Br2 ? 44.0 grams Br2 (1 mole Br2/159.8 grams)(6.022 X 10^23/1 mole Br2)(1 mole Br2 atoms/6.022 X 10^23) = 0.275 moles of Br2 atoms
When potassium bromide (KBr) reacts with chlorine gas (Cl2), it forms potassium chloride (KCl) and bromine (Br2). This reaction is a redox reaction, with bromide ions being oxidized to bromine gas and chlorine being reduced to chloride ions.

The reaction you mentioned involves the phase change of bromine from gas (Br2(g)) to liquid (Br2(l)). The standard enthalpy change for this process, represented as ΔH°, is 30.91 kJ/mol, indicating that this amount of energy is released when one mole of bromine gas condenses into a liquid at standard conditions. The value of ΔHf for Br2(g) typically refers to the enthalpy of formation for bromine gas, which is defined as zero since it is the standard state of the element.
Bromine has a diatomic molecule, Br2.
The reaction 2KBr → 2K + Br2 is endothermic because heat must be supplied to break the bonds in potassium bromide (KBr) in order to form potassium (K) and bromine gas (Br2).
2NaBr (s) + Cl2 (g) --------> 2NaCl (s) + Br2 (g)
The chemical reaction is:2 HI + Br2 = 2 HBr + I2
The correct chemical equation for the reaction is: Cl2 + 2KBr → 2KCl + Br2. The reaction involves chlorine gas (Cl2) reacting with potassium bromide (KBr) to form potassium chloride (KCl) and bromine gas (Br2).
Br2 + 3NaHSO3 = 2NaBr + NaHSO4 + H2O + 2SO2
Equation:N2 + 3 Br2 ----> 2 NBr3
The chemical equation is:2 AlBr3 + 3 Cl2 = 2 AlCl3 + 3 Br2
Bromine exists as a diatomic gas. Thus, there are two moles of bromine atoms in 1 mole of bromine gas.
