The energy input and work output (per cycle) for two different heat engines is recorded in this table. Which statement is true about the two engines?

A)
Engine I wastes 0.4 kJ more energy than Engine II.
B)
Engine Il wastes 0.4 kJ more energy than Engine I.
Engine I wastes 0.6 kJ more energy than Engine II.
D)
Engine II wastes 0.6 kJ more energy than Engine I.

I’m not sure what your trying to say here.. can you clarify again?

Ibelieve it's celsius. hope this .

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
