Introduction to Biochemistry Next time you’re at the gym, think about the fact that all the cells in your body are working together to achieve your goals. Petalite (Li Al Si 4 O 10) was discovered in 1800 by the Brazilian chemist José Bonifácio de Andrada in a mine on the island of Utö, Sweden. However, it was not until 1817 that Johan August Arfwedson, then working in the laboratory of the chemist Jöns Jacob Berzelius, detected the presence of a new element while analysing petalite ore. Alkali-activated materials (AAM) are recognized as potential alternatives to ordinary Portland cement (OPC) in order to limit CO 2 emissions as well as beneficiate several wastes into useful products. A Lewis acid is a chemical species that contains an empty orbital which is capable of accepting an electron pair from a Lewis base to form a Lewis adduct. GCSE/IGCSE Chemistry Quizzes Section 1.
