Answer:
C) It is the reactant that is left over after the reaction stops.
Explanation:
The excess reactant is the reactant that is left over after the reaction stops. The extent of the reaction is not determined by this reactant.
A limiting reactant is a reactant that is in short supply within a given reaction.
Such reactants determines the extent of chemical reaction.
- Limiting reactants are used up in a chemical reaction.
- The excess reactants remains unchanged after the reaction.
Answer: It’s correct because it’s showing an exothermic reaction. x is the reactants and y is the products.
Explanation: -ΔH means the reaction is exothermic and releasing heat. This lowers the potential energy.
