Which statement accurately describes this graph? it represents an endothermic reaction because the products have more energy than the reactants. it represents an exothermic reaction because the products have more energy than the reactants. it represents an endothermic reaction because the reactants have more energy than the products. it represents an exothermic reaction because the reactants have more energy than the products.

This is an exothermic graph. the answer is "It represents an exothermic reaction because the reactants have more energy than the products."

remember that the reactants in the straight line in the left side; the products are the straight line on the right side.

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
