A single replacement reaction can be represented by the equation AB + C = AC + B
Answer:
65°C
Explanation:
Formula for calorimetry is:
Q = C . m . ΔT
Where Q is heat, C is specific heat, m is mass and ΔT is the difference between final T° and initial.
We have all data to replace.
First of all, we convert kJ to J → 4.94 kJ . 1000 J / 1 kJ = 4940 Joules
We made this conversion because the unit of C, is in J
As heat is lost, we have to think in a negative value. Let's replace:
- 4940 J = 4.18 J/ g °C . 35 g . ( Final T° - 98.8°C)
- 4940 J / (4.18 J/ g °C . 35 g) = Final T° - 98.8°C
Final T° = - 4940 J / (4.18 J/ g °C . 35 g) + 98.8°C
Final T° = 65.03 °C
Notice, that this answer has sense because as T° decreased, heat has been lost.
