Answer:
reactants are two ionic compounds. Explanation: A double-replacement reaction is different from a single-replacement reaction because a double-replacement reaction is a reaction between two ionic compounds while in a single-replacement reaction one atom replace another atom.
Answer:
The correct answer is: <em>There must be potential energy in the bonds due to its particles position.</em>
Explanation:
Potential energy is a kind of energy which is stored in an object due to its position or configuration. For example, if there is a ball in the fifth floor of a building, it has a determined potential energy which is converted to kinetic energy when the ball fall down. The same is in the case of the chemical bonds: the particles or atoms have potential energy related to their relative positions in the system. In fact, chemical energy is considered a form of potential energy (stored in chemical bonds).
