Question

how much heat is evolved in the burning of 1.6 grams of hexanegiven the following: 2C6h14 + 19O2 ---> 12 CO2 + 14 H2O +14H2O        = (-8326kJ) and question 2: what is the value of heat capactity C of c7h8 given the factthat the absorption of a 186J of heat is required to raise thetemperature of a 16 gram sample of c7h8 from 22.3*C to29.6*C??? how much heat is evolved in the burning of 1.6 grams of hexanegiven the following: 2C6h14 + 19O2 ---> 12 CO2 + 14 H2O +14H2O        = (-8326kJ) and question 2: what is the value of heat capactity C of c7h8 given the factthat the absorption of a 186J of heat is required to raise thetemperature of a 16 gram sample of c7h8 from 22.3*C to29.6*C???

Explanation / Answer

I didn't do the first one but it looks reasonable based on thenumbers. The second one is Q=-(mct). 186 J = 16g * C * (29.6-22.3) C = 186/(16*7.3) = 1.59 J/gC, to 3 sig digs. Check your numbers
