Answer:
14835 J
Step-by-step explanation:
Recall that heat capacity, C, is the ratio of heat to the change in temperature.
C= q/ΔT
Rewrite the equation to solve for q.
q=CΔT
In order to solve for q, you must first calculate ΔT.
ΔT=Tfinal−Tinitial
ΔT=45.0∘C–88.0∘C=−43.0∘C
Next, Substitute the known values into the equation above and solve for q.
q=(345J∘C)(−43.0∘C)= −14,835 J
Round your answer to the nearest hundred to use correct significant figures.
q= −14,800 J
The negative sign means that heat is released, or the process is exothermic. Therefore, the amount of heat released is about 14,800 J.
