The energy of the universe has to be predicted. Concept introduction: Thermodynamics is the branch of science that relates heat and energy in a system. The four laws of thermodynamics explain the fundamental quantities such as temperature, energy and randomness in a system. Entropy is the measure of randomness in a system. For a spontaneous process there is always a positive change in entropy. Spontaneous process: A process which is initiated by itself, without the help of external energy source is called spontaneous process. All spontaneous process is associated with the decrease in free energy in the system. First law of thermodynamics: According to first law, the total energy of the universe remains constant.

Definition Definition Transformation of a chemical species into another chemical species. A chemical reaction consists of breaking existing bonds and forming new ones by changing the position of electrons. These reactions are best explained using a chemical equation.

Interpretation Introduction
Interpretation:
The creation or destruction of energy has to be predicted.
Concept introduction:
Any natural process or a chemical reaction taking place in a laboratory can be classified into two categories, spontaneous or nonspontaneous. Spontaneous process occurs by itself, without the influence of external energy. In spontaneous process the free energy of the system decreases and entropy of the system increases. Nonspontaneous process requires an external influence for initiation. In nonspontaneous process the free energy of the system increases but entropy of the system decreases.
(c)
Interpretation Introduction
Interpretation:
For the energy change of system and surroundings should be explained.
Concept introduction:
In thermodynamics a process is spontaneous if it is taking place by itself without the help of external energy. All spontaneous process will have highly energetic initial state than the final state. This indicates that while the process occurs, there is a decrease in free energy of the system. The increase in randomness also favors the spontaneity of a process.
In non-spontaneous process, there is a requirement of external energy source. The free energy of the system increases. The entropy decreases in non-spontaneous process.
What impact would adding twice as much Na2CO3 than required for stoichiometric quantities have on the quantity of product produced? Initial results attached
Given that a theoretical yield for isolating Calcium Carbonate in this experiment would be 100%. From that information and based on the results you obtained in this experiment, describe your success in the recovery of calcium carbonate and suggest two possible sources of error that would have caused you to not obtain 100% yield.

5) Calculate the flux of oxygen between the ocean and the atmosphere(2 pts), given that:
(from Box 5.1, pg. 88 of your text):
Temp = 18°C
Salinity = 35 ppt
Density = 1025 kg/m3
Oxygen concentration measured in bulk water = 263.84 mmol/m3
Wind speed = 7.4 m/s
Oxygen is observed to be about 10% initially supersaturated
What is flux if the temperature is 10°C ? (2 pts) (Hint: use the same density in your calculations). Why do your calculated values make sense (or not) based on what you know about the relationship between gas solubility and temperature (1 pt)?
