Answer:
The chemical equation A2 + B2 ———> A2B is unbalanced.
Step-by-step explanation:
To balance a chemical equation, the same number of each type of atom must appear on both sides of the equation. In this case, the left side has 2 atoms of A and 2 atoms of B, while the right side has 2 atoms of A and 1 atom of B. For the equation to be balanced, you should have the same number of A and B atoms on both sides.
Balancing chemical equations is important because it ensures that the law of conservation of mass is upheld. This law states that matter cannot be created or destroyed in a chemical reaction, only rearranged. When an equation is balanced, it means that the same number of each type of atom exists before and after the reaction. Balancing equations is a fundamental concept in chemistry and is crucial for understanding the stoichiometry of chemical reactions and making accurate predictions about reactants and products.
