The constituents of petroleum and natural gas, petroleum “fractions” and the explanation corresponding to their uses are to be stated. The meaning of cracking petroleum and the reason as to why the cracking of petroleum is done are to be stated. The uses of tetraethyl lead and the reason of reduction in its use are to be stated. The explanation corresponding to the greenhouse effect and the reason as to why scientists are concerned about it are to be stated. Concept Introduction: Millions of years ago, dead organisms were embedded in the sea due to various tragedies such as flood and earthquake. These dead organisms were completely shielded with sand and clay. The absence of oxygen, high pressure and temperature converted them into natural gas and petroleum. In this way, the formation of petroleum takes place. Refining is the process, which is used to purify the desired substances. It removes the impurities from petroleum and it is followed by distillation that aid in the isolation of different fractions of petroleum.

Concept Introduction:
Millions of years ago, dead organisms were embedded in the sea due to various tragedies such as flood and earthquake. These dead organisms were completely shielded with sand and clay. The absence of oxygen, high pressure and temperature converted them into natural gas and petroleum. In this way, the formation of petroleum takes place. Refining is the process, which is used to purify the desired substances. It removes the impurities from petroleum and it is followed by distillation that aid in the isolation of different fractions of petroleum.
Using appropriate chemical reactions for illustration, show how calcium present as the dissolved HCO3- salt in water is easier to remove than other forms of hardness, such as dissolved CaCl2.
Green plants use carbon dioxide for photosynthesis and return oxygen to the atmosphere, even then carbon dioxide is considered to be responsible for the greenhouse effect. Explain why?
Explain the Greenhouse Effect: Global Warming and Climate Change.
Consider an ionic compound, MX3, composed of generic metal M and generic gaseous halogen X.
The enthalpy of formation of MX3 is Δ?∘f=−925 kJ/mol.
The enthalpy of sublimation of M is Δ?sub=175 kJ/mol.
The first, second, and third ionization energies of M are IE1=579 kJ/mol, IE2=1677 kJ/mol, and IE3=2479 kJ/mol.
The electron affinity of X is Δ?EA=−369 kJ/mol. (Refer to the hint).
The bond energy of X2 is BE=179 kJ/mol.
Determine the lattice energy of MX3.
