Ac sample of octane that has a mass of 0.750 g is burned in a bone calorimeter. as a result, the temperature if the calorimeter increases from 21.0 °c to 41°c . the specific heatv of the calorimeter is 1.50 j/(g*°c), and it's nass is 1.0 kg. how much heat is released during the combustion

Sugar is dissolved in water. which is the solute? sugar neither both water

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
