Answer:
Decomposition Reaction
2 AgCO₃ -----> 2 Ag + 2 C + 3 O₂
Step-by-step explanation:
During the reaction, the reactant breaks down into smaller elements/compounds. As such, this is a decomposition reaction.
An equation is balanced when there is an equal amount of each element on both sides of the reaction. If these amounts are unequal, you can add coefficients to modify the quantities of particular elements/compounds. These coefficients must be as small as they can be while remaining whole numbers.
The unbalanced equation:
AgCO₃ -----> Ag + C + O₂
Reactants: 1 silver, 1 carbon, 3 oxygen
Products: 1 silver, 1 carbon, 2 oxygen
The balanced equation:
2 AgCO₃ -----> 2 Ag + 2 C + 3 O₂
Reactants: 2 silver, 2 carbon, 6 oxygen
Products: 2 silver, 2 carbon, 6 oxygen
