3. Some Chem 16.1 students were tasked to perform the ideal gas experiment with some modifications. Instead of magnesium ribbon, the students were to use 0.029 g of aluminum foil. They prepared the eudiometer by adding 6M HCI and filling it with water to the brim. Once the setup was complete, they performed the experiment. Note that the aluminum was completely consumed in the reaction. From the experiment, it was found that the external pressure was 1.05 atm at
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
answer all ty
c. find the experimental mass of aluminum consumed in the reaction
d. find the % error of the mass of aluminum from the experiment
![3. Some Chem 16.1 students were tasked to perform the ideal gas experiment
with some modifications. Instead of magnesium ribbon, the students were to use
0.029 g of aluminum foil. They prepared the eudiometer by adding 6M HCI and
filling it with water to the brim. Once the setup was complete, they performed the
experiment. Note that the aluminum was completely consumed in the reaction.
From the experiment, it was found that the external pressure was 1.05 atm at
30.0 °C, and the volume of the air inside the eudiometer was 33.5 mL. The water
level inside the eudiometer is 4.15 cm below the surface of the water level
outside. Given these measurements and the following constants, answer the
proceeding questions.
• At 30.0 °C, Pvapor = 31.8 mmHg
R 0.08206 L-atm/mol-K= 62.36 L-torr/mol-K
