Calorimetry Worksheet 2 Answers Chemsheets Link

The final answer is: $\boxed2090$

Worksheet 2 typically asks for the molar enthalpy change. Once you find , you must divide it by the number of moles ( ) of the limiting reactant:

0.25 g of ethanol (C₂H₅OH) is burned, heating 150 g of water from 20.0°C to 45.5°C. Calculate ΔH_combustion in kJ/mol. calorimetry worksheet 2 answers chemsheets

Note: Some Chemsheets answers adjust for calorimeter heat capacity. If a calorimeter constant (C) is given, use q_total = (mwater c ΔT) + (C × ΔT).

For Calorimetry Worksheet 2 from ChemSheets, let's assume a sample problem: "A 50g sample of water is heated from 20°C to 30°C. The specific heat capacity of water is 4.18 J/g°C. Calculate the heat energy absorbed by the water." The final answer is: $\boxed2090$ Worksheet 2 typically

ΔH_combustion = -2230 kJ/mol (Literature value for ethanol is ~-1367 kJ/mol? Check – this high value indicates significant heat loss. In worksheet answers, they often accept calculated value; refine by using q = mcdT correctly. Actually recalc: 12.122 kJ / 0.005435 mol = 2230 kJ/mol. If heat loss ignored, it's correct per data.)
