no explanation needed Course dashboard A bomb calorimetry experiment is performed with xylose, C.H100s (8), as the combustible substance. The data obtained are: mass of xylose burned: 1.823g; heat capacity of calorimeter 4.728 kJ/°C; initial calorimeter temperature: 23.29°c; final calorimeter temperature 27.19°C What is the heat of combustion of xylose, in kilojoules per mole? Select one O a.-2.17x10 kJ/mol O b.-1.52x103 kJ/mol OC.-5.64x103 kJ/mol O d. 1.17x10 kJ/mol e.-2.38x10 kJ/mol

At x-values where g is positive, G should be increasing • At x-values where g is increasing, G should be positive . Any value of G can be determined by the formula G(X) = 1+Sg(t) dt. This formula will tell us the net signed area of the G graph at a given x- value.
