Example Problem and Solution

Problem: When 0.5 g of magnesium is added to 100 mL of 1 M HCl, the temperature of the solution increases from 22.0°C to 28.0°C. Calculate the enthalpy change for the reaction.

Assumptions: Specific heat capacity of solution = 4.18 J/g°C, density of solution ≈ 1 g/mL.

Solution:

1. Calculate the mass of the solution: 100 mL * 1 g/mL = 100 g
2. Calculate (q): (q = mc\Delta T = 100 , \textg \times 4.18 , \textJ/g°C \times (28.0°C - 22.0°C) = 100 \times 4.18 \times 6 = 2508 , \textJ)
3. Convert (q) to kJ: (2508 , \textJ = 2.508 , \textkJ)

This value represents the heat released to the surroundings. To find the (\Delta H) per mole of magnesium reacted, we need the number of moles of magnesium: (0.5 , \textg / 24.3 , \textg/mol = 0.0206 , \textmol)

(\Delta H = -2.508 , \textkJ / 0.0206 , \textmol = -121.7 , \textkJ/mol)

Calorimetry Worksheet 2 — Answers (ChemSheets)

Here are clear, concise answers for Calorimetry Worksheet 2. Adjust any numeric values or significant figures to match your worksheet's given data.

1. Specific heat of aluminum (example)

• Given: mass Al = 25.0 g, initial T = 22.0 °C, final T = 28.5 °C; water mass = 50.0 g, water initial T = 22.0 °C; assume cw = 4.184 J/g·°C.
• ΔT_Al = 22.0 − 28.5 = −6.5 °C → use magnitude 6.5 °C.
• q_water = (50.0 g)(4.184 J/g·°C)(28.5 − 22.0) = 50.0×4.184×6.5 = 1360 J.
• q_Al = −q_water = −1360 J.
• c_Al = q_Al / (m_Al ΔT_Al) = (−1360 J) / (25.0 g × −6.5 °C) = 0.838 J/g·°C.

2. Heat of fusion of ice (example)

• Given: mass ice = 10.0 g at 0.0 °C added to 100.0 g water at 25.0 °C; final T = 15.0 °C.
• Heat lost by water: q_water = (100.0 g)(4.184)(25.0 − 15.0) = 100×4.184×10 = 4184 J.
• Heat gained to warm melted ice from 0 to 15 °C: q_warming = (10.0 g)(4.184)(15.0 − 0) = 627.6 J.
• Heat available to melt ice: q_melt = q_water − q_warming = 4184 − 627.6 = 3556.4 J.
• ΔH_fus = q_melt / mass_ice = 3556.4 J / 10.0 g = 355.6 J/g → 355.6 J/g or 6.02 kJ/mol (use molar mass 18.015 g/mol: 355.6 J/g × 18.015 g/mol = 6.40 kJ/mol — adjust to worksheet convention).

3. Calorimeter constant determination (example)

• Given: hot metal mass 30.0 g at 90.0 °C dropped into 150.0 g water at 20.0 °C; final T = 25.0 °C; c_metal = 0.385 J/g·°C.
• q_metal = (30.0)(0.385)(90.0 − 25.0) = 30×0.385×65 = 750.75 J released.
• q_water = (150.0)(4.184)(25.0 − 20.0) = 150×4.184×5 = 3138 J absorbed.
• Net absorbed by calorimeter = q_metal − q_water = 750.75 − 3138 = −2387.25 J (negative means more absorbed by water; take magnitude 2387.25 J).
• Calorimeter constant C_cal = energy absorbed by calorimeter / ΔT = 2387.25 J / (25.0 − 20.0 = 5.0 °C) = 477.45 J/°C.

4. Determining specific heat of an unknown (example)

• Given: unknown mass 20.0 g at 80.0 °C into 100.0 g water at 22.0 °C; final T = 26.0 °C; C_cal = 50.0 J/°C.
• q_water = (100)(4.184)(26.0 − 22.0) = 1673.6 J.
• q_cal = C_cal × ΔT = 50.0 × (26.0 − 22.0) = 200 J.
• q_unknown = −(q_water + q_cal) = −(1673.6 + 200) = −1873.6 J.
• c_unknown = q_unknown / (m ΔT) = (−1873.6) / (20.0 × (26.0 − 80.0 = −54.0)) = 1873.6 / (20×54) = 1.735 J/g·°C.

5. Example conceptual question — why use final equilibrium temperature?

• The system reaches thermal equilibrium where no net heat flows; using final T ensures energy conservation between components.

Notes:

• Sign convention: q positive = heat gained; q negative = heat lost. For solving, you can set sum of q for system = 0.
• Use given significant figures from your worksheet data when reporting final answers.
• If your worksheet has different numbers, substitute them into the same equations:
  • q = m c ΔT
  • Conservation: Σq = 0 (including calorimeter heat: q_cal = C_cal ΔT)
  • For phase changes: q = m ΔH (no temperature change during phase change).

While "Calorimetry Worksheet 2" might look like a standard collection of numbers and units on a page, it is actually a map of the hidden energy exchanges that power our universe. At its heart, calorimetry is the science of measuring heat—the invisible currency of thermodynamics. When we work through these problems, we aren't just solving for ; we are quantifying the very breath of chemical reactions. The Silent Flow of Energy

Every calculation on a Chemsheets worksheet tells a story of transformation. When a substance dissolves or a fuel burns, bonds are broken and formed, releasing or absorbing energy. We use a calorimeter—essentially a thermal "vault"—to ensure that no energy escapes our observation. By measuring the temperature change of water, we can deduce exactly how much "work" a specific amount of matter can perform. It is a bridge between the microscopic world of vibrating atoms and the macroscopic world we can feel with our fingertips. The Precision of the Method Specific Heat Capacity : The worksheet provides questions

The beauty of these worksheets lies in their logic. To find the answers, a student must account for three critical variables: Mass ( ): The amount of "stuff" absorbing the energy. Specific Heat Capacity (

): The unique "thermal personality" of the substance (usually water's reliable ). Change in Temperature ( ΔTcap delta cap T ): The physical evidence of the energy's movement. When we multiply these together, we get

(heat energy). However, the true "aha!" moment comes when we convert that energy into Enthalpy Change ( ΔHcap delta cap H

). This step elevates the math from a simple observation to a universal law, allowing us to predict how much heat a kilogram of fuel will produce based on a single gram burned in a lab. Why the Answers Matter

Solving for the answers on Chemsheets Worksheet 2 is more than an academic hurdle; it is a lesson in the Law of Conservation of Energy. It teaches us that energy is never lost; it is only transferred. Whether we are calculating the enthalpy of neutralization or the combustion of an alcohol, we are practicing the same skills used by engineers to design safer batteries, by nutritionists to calculate food calories, and by climatologists to track how the oceans absorb solar heat.

In the end, calorimetry proves that the universe keeps a perfect set of books. Every joule must be accounted for, and every degree of temperature rise is a clue to the fundamental forces that hold our world together.

Introduction to Calorimetry

Calorimetry is the science or practice of measuring the changes in heat energy that occur during chemical reactions or physical changes. This technique is fundamental in understanding thermodynamics, which is the study of the relationships between heat, work, and energy. Calorimetry can be used to determine the heat capacity of materials, the specific heat capacity of substances, and the enthalpy change (ΔH) of reactions.
