need help on 5 and 6
0 2.00 g of octane, C8H18 was burned in a bomb calorimeter causing the temperature to increase from 21.0°C to 35.5°C. The total heat capacity of the calorimeter was 0.05 KJP C. Calculate the heat of combustion for the reaction shown below. 2 C8H18(1) + 2502(g) → 16 CO2(g) + 18 H2O(g) 6. When 50.0 mL of 0.100 M AgNO3 was reacted with 50.0 mL of 0.100 M HCl in a .

E AFTER COMPLETING LAB. ANSWER IN SPACE PROVIDED. Suppose the heat of neutralization had been determined using a glass beaker instead of a polystyrene coffee cup How would the measured value have been affected? The heat of combustion of octane, C,H,. can be measured in a way similar to the method youC used to measure the heat of neutralization. The bomb calorimeter is used instead of a coffee cup. The reaction is 2C,H,1)+ 25 O, (g) 16 CO, (g) +...

Please help with these two questions :(
1. How much energy (in kJ) is evolved during the reaction of
76.9 g of Al, according to the reaction below?
Fe2O3(s) + 2 Al(s) →
Al2O3(s) + 2 Fe(s) ΔH°rxn = -852
kJ
Assume that there is excess Fe2O3.
2. A 12.43 g sample of ethanol (C2H5OH) is
burned in a bomb calorimeter with a heat capacity, C = 5.65
kJ/°C.
C2H5OH(l) + 3 O2(g) → 2
