Question

Balance the following equation:

Li + FeBr_2 → LiBr + Fe

a) 2Li + 2FeBr_2 → 2LiBr + 2Fe
b) Li + 2FeBr_2 → LiBr + Fe
c) 2Li + FeBr_2 → LiBr + 2Fe
d) Li + FeBr_2 → LiBr + Fe

Answer 1

To balance the reaction between lithium (Li) and iron(II) bromide (FeBr2) to produce lithium bromide (LiBr) and iron (Fe), the correctly balanced chemical equation is option a: 2Li + 2FeBr2 → 2LiBr + 2Fe.

Step-by-step explanation:

To find the balanced chemical equation for the reaction of lithium (Li) with iron(II) bromide (FeBr2) to produce lithium bromide (LiBr) and iron (Fe), we must ensure the same number of each type of atom on both sides of the equation. Checking the proposed options:

• Option a: 2Li + 2FeBr2 → 2LiBr + 2Fe
• Option b: Li + 2FeBr2 → LiBr + Fe
• Option c: 2Li + FeBr2 → LiBr + 2Fe
• Option d: Li + FeBr2 → LiBr + Fe

By observing the reactants and products, we can determine that option a is the correct balanced chemical equation. There are 2 lithium atoms, 2 iron atoms, and 4 bromine atoms on both sides of the equation.
