A 1500.0 gram piece of wood with a specific heat capacity of 1.8 g/JxC absorbs 67,500 Joules of heat. If the final temperature of the wood is 57C, what is the initial temperature of the wood?

Outermost (valence) electrons

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

The answer is conduction
