Identify the following reactions as exothermic or endothermic. YOU MUST USE THE FOLLOWING VOCABULARY WORDS in your answer
endothermic/exothermic (choose one)
Reactant
Thermal kinetic energy
Product
O
Chemical potential energy
1. C2H - 2C + 2H, + heat
This is an
I know this because
2. 2Fe + 3C0, + 26.8kJ → Fe2O3 + 3C0
This is an
I know this because
3. 2HgO - 2Hg + O2
AH= +181 kJ
This is an
I know this because

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
