Answer:
trial 1: % error = 3.546 %
trial 2: % error = 3.073 %
trial 3: % error = 0.946 %
Explanation:
- % error = ((ΔHi - ΔH) / ΔH) ×100
∴ ΔH = - 42.3 KJ/mol
trial 1:
∴ ΔH1 = - 43.8 KJ/mol
⇒ % error = ((-43.8 - ( -42.3 )) / ( -42.3 ))×100
⇒ % error = (0.03546)*100 = 3.546 %
trial 2:
∴ ΔH2 = - 41.0 KJ/mol
⇒ % error = ((-42.3 - ( -41.0 )) / ( -42.3 ))×100
⇒ % error = (0.03073)*100 = 3.073%
trial 3:
∴ ΔH3 = - 42.7 KJ/mol
⇒ % error = ((-42.7 - ( -42.3 )) / ( -42.3 ))×100
⇒ % error = (9.456 E-3)*100 = 0.946 %
Earth's internal heat budget is fundamental to the thermal history of the Earth. The flow of heat from Earth's interior to the surface is estimated at {\displaystyle 47\pm 2} terawatts (TW)[1] and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of the Earth.[2]
Earth's internal heat powers most geological processes[3] and drives plate tectonics.[2]Despite its geological significance, this heat energy coming from Earth's interior is actually only 0.03% of Earth's total energy budget at the surface, which is dominated by 173,000 TW of incoming solar radiation.[4] The insolation that eventually, after reflection, reaches the surface penetrates only several tens of centimeters on the daily cycle and only several tens of meters on the annual cycle. This renders solar radiation minimally relevant for internal processes.[

Transportation seems like the right answer
The light bulbs ave to be a part of the loop in order for it to be successful because it have to have wires to a circuit breaker so you can see.
