Explanation:
Given equation of reaction:
Li + Br₂ → LiBr
In balancing any chemical equation, they must obey the law of conservation of matter. This law suggests that the number of moles of reactants and products must be the same in a chemical reaction.
This suggests that no amount of matter is lost during a chemical reaction.
The reaction above is a combination reaction in which two species combines to give a product.
To balance chemical reactions, we can simply inspect and assign the appropriate coefficient to the reactants and products. The coefficients should be whole numbers.
Also, the approach here would be mathematical where we would derive simple and solvable algebraic expressions to address the problem.
Assign alphabets a, b and c to the species;
aLi + bBr₂ → cLiBr
Conserving Li; a = c
Br; 2b = c
let b = 1;
c = 2
a = 2
The coefficients are 2, 1 and 2
The balanced equation is:
2Li + Br₂ → 2LiBr
