In this lab activity, you will calculate the enthalpy change for the thermal decomposition of
What is the molar enthalpy of reaction for the thermal decomposition of sodium hydrogen
carbonate at standard conditions?
Purpose: To construct a heating curve for water and calculate the amount of heat required to heat and boil a given amount of water. Materials: 150 mL beaker, hot plate, PASCO probe, beaker tongs, and graduated cylinder. Procedure: 1. Create an experiment
Using the Specific Heat Equation, q = m c T 1. A chemist burns one serving size of this product to determine its calorie content. She finds that the reaction heats up 1555 grams of water by 154 degrees Celsius. a) Calculate the energy content in kilocalor
Calorimetry is a technique that is used to determine the amount of heat gained or lost
during a chemical reaction. A calorie is the energy needed to raise the temperature of 1
gram of water 1 degree Celsius. Our energy is obtained from the burning of the
1 Obtain a dry watch glass. Place aluminum foil around the watch glass.
Record the mass in the data table.
2 Place the dorito on the watch glass and obtain the mass of the item and the
watch glass. Subtract the empty watch glass mass from the t
In this lab, we are going to determine the molar mass of butane, C4H10, experimentally. A simple
calculation using a periodic table would give us the correct answer for the molar mass of butane,
however, you are going to conduct an exp
Lab: Determine of the concentration of stomach acid by titration with a strong base
Background information: Gastric acid is, together with several enzymes and the intrinsic factor, one of the main secretions of the stomach. Chemically it is an acid soluti
The chemical reactions, which cause acid rain to develop. 2. 3. 4. 5. 6. 7. 8. 9. What reactants are involved and what products are created. What is the pH of acid rain and how does that compare to other substances in our What is acid rain? Where do these
Acid rain is attributed to pollutants from industrial emissions. It rains
down on us and destroys flora, animal life, endangers our health and causes
considerable property damage.
