Balanced the tarnishing equation:
2Ag(s) + 1H₂S(g) → 1Ag₂S(s) + 1H₂(g).
According to principle of mass conservation, number of atoms must be equal on both side of balanced chemical reaction.
There are two silver atoms, two hydrogen atoms and one sulfur atom on both side of balanced chemical reaction.
The coefficients that will balance the tarnishing reaction equation are: 2, 1, 1,1
Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.
The reactants are located on the left side while the products are located on the right side.
Reactants —> Products
The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.
Thus, we can obtain the coefficients that will balance the tarnishing reaction equation by simply balancing the equation:
Ag(s) + H₂S(g) → Ag₂S(s) + H₂(g)
There are 2 atoms of Ag on the right side and 1 atom on the left side. It can be balanced by writing 2 before Ag as shown below:
2Ag(s) + H₂S(g) → Ag₂S(s) + H₂(g)
Thus, the equation is balanced.
The coefficients are: 2, 1, 1, 1
