Question

A 0.557-g sample of para-benzoquinone ($C_6H_4O_2$) is burned in a bomb calorimeter and the temperature increases from 25.80 $^\circ$C to 28.10 $^\circ$C. The calorimeter contains 1.19$\times10^3$ g of water and the bomb has a heat capacity of 912 J/$^\circ$C. Based on this experiment, calculate $\Delta E$ for the combustion reaction per mole of para-benzoquinone burned (kJ/mol). $C_6H_4O_2(s) + 6 O_2(g) \longrightarrow 6 CO_2(g) + 2 H_2O(l)$ $\Delta E = $ ____ kJ/mol

Step 1

18 J/g°C) ΔT = change in temperature (final temperature - initial temperature) Substitute the given values: m = 1.19 * 10^3 g c = 4.18 J/g°C ΔT = 28.10°C - 25.80°C Calculate q. Show more…

A 0.557 -g sample of para-benzoquinone (C_(6)H_(4)O_(2)) is burned in a bomb calorimeter and the temperature increases from 25.80deg C to 28.10deg C. The calorimeter contains 1.19 imes 10^(3)g of water and the bomb has a heat capacity of 912(J)/(deg )C. Based on this experiment, calculate Delta E for the combustion reaction per mole of para-benzoquinone burned (k(J)/(m)ol).
