Question

A sample of hexane (c6H14) has a mass of 0.580 g. The sample is burned in a bomb calorimeter that has a mass of 1.900 kg and a specific heat of 3.21 J/g times K. What amount of heat is produced during the combustion of hexane if the temperature of the calorimeter increases by 4.542 k?

Answer 1

The answer would be c 27.7

Step-by-step explanation:

Took the test

Answer 2

The amount of heat produced during combustion is 27701.7 j


calculation
use Q = M CΔT formula where
Q(heat) =?
M(mass)= 1.900Kg in g = 1.900 x1000 = 1900 g
C(specific heat capacity) = 3.21 j/g /k
ΔT = change in temperature = 4.542 K

Q is therefore = 1900 g x 3.21 j/g/k x4.542 k = 27701.7 J
