Public Lecture: Non-Calculus Quantum Chemistry to Understand Organic and Inorganic Chemistry - This public lecture was delivered by Dr.  M. Abdulkadir Martoprawiro or who is familiarly called Dr. Kaka is a lecturer at the Bandung Technology University (ITB). This public lecture is fresh knowledge not only for chemistry undergraduate students but also chemistry masters students at FMIPA Tanjungpura University.

Dr. Kaka (hijau) and Dr. Andi Hairil 

Quantum Chemistry itself is a branch of chemistry that began to be developed in 1920 to study chemical bonds and reactions not only for organic compounds but also for inorganic compounds. With Quantum Chemistry we can understand how to predict the structure of various materials along with their properties and mechanisms when they react with other compounds or elements.

For example, is the formation of ice cubes from water in the refrigerator an endothermic reaction? There are those who answer yes, no and there are also those who answer that both reactions, endothermic and exothermic, occur. The reason is because the answerer assumes that there are two environments during the process of forming ice cubes. The first environment is inside the refrigerator, the second environment is outside the refrigerator (where heat is removed from inside the refrigerator). Of course, in this case, there is only one environment in question, namely inside the refrigerator where the change in the state of water occurs.

Undergraduate and Masters Chemistry students attended the Non-Calculus Quantum Chemistry Public Lecture to Understand Organic and Inorganic Chemistry with Dr. Brother

For Quantum Chemistry, nowadays predictions of the structure, properties and mechanisms of chemical compounds are indeed easier to do with the development of technology, mathematics and the existence of chemical computing.
